How we balance a chemical equations |
|
Answer» By hit and trial method I hope you understand. Identify\xa0each element found in\xa0the equation. The number of atoms of each type of atom must be the same on each side of the equation once it has been\xa0balance.What is the net charge on each side of the equation? The net charge must be the same on each side of the equation once it has been balanced.If possible, start with an element found in one compound on each side of the equation. Change the coefficients (the numbers in front of the compound or molecule) so that the number of atoms of the element is the same on each side of the equation. Remember,\xa0to balance an equation, you change the coefficients, not the subscripts in the formulas.Once you have balanced one element, do the same thing with another element. Proceed until all elements have been balanced. It\'s easiest to leave elements found in pure form for last.Check your work to make certain the charge on both sides of the equation is also balanced.Thank you..... |

Explain sexual reproduction in human female?? |
| Answer» The\xa0female reproductive system\xa0is active before, during and after fertilization as well. It consists of the following parts:\tA pair of ovaries:\xa0Ovaries produce and store ovum in them. They also produce a female hormone called estrogen.\tFallopian tubes (Oviducts):\xa0They are the site of fertilization. They connect ovaries with the uterus.\tUterus:\xa0Uterus is the site of development for the embryo.\t******:\xa0It is the part which connects the cervix to the external female body parts. It is the route for the ***** during coitus as well as a fetus during delivery.Female reproductive system has two functions –\tProduction of female gamete called ovum/egg.\tProviding nutrition and protecting the developing embryo.During puberty, eggs in the ovaries start to mature. One of the ovaries releases the matured ovum in every 28 to 30 days and is called ovulation. | |

Give point wise answer of importance of variation ( bio) |
|
Answer» Thanks but I want point wise answer Genetic variationis advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population. Genetic\xa0variation\xa0creates a larger pool of traits in a species so that\xa0given\xa0a novel environment, at least someone would have the trait needed to survive.\xa0Variation\xa0allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic\xa0variation\xa0within a population usually enables more phenotypic\xa0variation. |

List the three events that occur during the process of photosynthesis ?? |
|
Answer» Thanks The process of photosynthesis takes place in the green leaves of a plant. The carbon dioxide gas required for making food is taken by the plant leaves from the air which enters the leaves through tiny pores called stomata. Water required for making food is taken from the soil which is transported to the leaves from the soil through the roots and the stem. The sunlight provides energy required to carry out the chemical reactions involved in the preparation of food. The green pigment called chlorophyll absorbs sunlight energy. The photosynthesis takes place in three steps:(i) Absorption of sunlight energy by chlorophyll.(ii) Conversion of light energy into chemical energy and splitting of water into hydrogen and oxygen by light energy.(iii) Reduction of carbon dioxide by hydrogen to form carbohydrates like glucose by utilising the chemical energy. |

What\'s is sperm |
|
Answer» Sperm is a male reproductive cell ,or gamete, in anisogamous forms of sexual reproduction.Animals produce motile sperm with a tail known as flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia Sperm is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, "female" reproductive cell and a smaller, "male" one). Animals produce motile sperm with a tail known as a flagellum, which are known as spermatozoa, while some red algae and fungi produce non-motile sperm cells, known as spermatia.[1] Flowering plants contain non-motile sperm inside pollen, while some more basal plants like ferns and some gymnosperms have motile sperm.[2]Diagram of a human sperm cellSperm cells form during the process known as spermatogenesis, which in amniotes (reptiles and mammals) takes place in the seminiferous tubules of the testes.[3] This process involves the production of several successive sperm cell precursors, starting with spermatogonia, which differentiate into spermatocytes. The spermatocytes then undergo meiosis, reducing their chromosome number by half, which produces spermatids. The spermatids then mature and, in animals, construct a tail, or flagellum, which gives rise to the mature, motile sperm cell. This whole process occurs constantly and takes around 3 months from start to finish.Sperm cells cannot divide and have a limited lifespan, but after fusion with egg cells during fertilisation, a new organism begins developing, starting as a totipotent zygote. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell. In mammals, sperm is stored in the epididymis and is released from the ***** during ejaculation in a fluid known as semen.The word sperm is derived from the Greek word σπέρμα, sperma, meaning "seed". |

The artificially created element 117, tennessine (Ts), may also be a halogen. In the modern IUPAC nomenclature, this group is known as group 17.HalogensHydrogenHeliumLithiumBerylliumBoronCarbonNitrogenOxygenFluorineNeonSodiumMagnesiumAluminiumSiliconPhosphorusSulfurChlorineArgonPotassiumCalciumScandiumTitaniumVanadiumChromiumManganeseIronCobaltNickelCopperZincGalliumGermaniumArsenicSeleniumBromineKryptonRubidiumStrontiumYttriumZirconiumNiobiumMolybdenumTechnetiumRutheniumRhodiumPalladiumSilverCadmiumIndiumTinAntimonyTelluriumIodineXenonCaesiumBariumLanthanumCeriumPraseodymiumNeodymiumPromethiumSamariumEuropiumGadoliniumTerbiumDysprosiumHolmiumErbiumThuliumYtterbiumLutetiumHafniumTantalumTungstenRheniumOsmiumIridiumPlatinumGoldMercury (element)ThalliumLeadBismuthPoloniumAstatineRadonFranciumRadiumActiniumThoriumProtactiniumUraniumNeptuniumPlutoniumAmericiumCuriumBerkeliumCaliforniumEinsteiniumFermiumMendeleviumNobeliumLawrenciumRutherfordiumDubniumSeaborgiumBohriumHassiumMeitneriumDarmstadtiumRoentgeniumCoperniciumNihoniumFleroviumMoscoviumLivermoriumTennessineOganessonchalcogens ← → noble gasesIUPAC group number\t17Name by element\tfluorine groupTrivial name\thalogensCAS group number(US, pattern A-B-A)\tVIIAold IUPAC number(Europe, pattern A-B)\tVIIB↓ Period2Image: Liquid fluorine at cryogenic temperaturesFluorine (F)9 Halogen3Image: Chlorine gasChlorine (Cl)17 Halogen4Image: Liquid bromineBromine (Br)35 Halogen5Image: Iodine crystalIodine (I)53 Halogen6Astatine (At)85 Halogen7Tennessine (Ts)117 HalogenLegendprimordial elementelement from decayAtomic number color:black=solid, green=liquid, red=gasvteThe name "halogen" means "salt-producing". When halogens react with metals, they produce a wide range of salts, including calcium fluoride, sodium chloride (common table salt), silver bromide and potassium iodide.The group of halogens is the only periodic table group that contains elements in three of the main states of matter at standard temperature and pressure. All of the halogens form acids when bonded to hydrogen. Most halogens are typically produced from minerals or salts. The middle halogens—chlorine, bromine, and iodine—are often used as disinfectants. Organobromides are the most important class of flame retardants, while elemental halogens are dangerous and can be lethally toxic |

Why does an aqeous solution of an acid conduct electricity? |
|
Answer» Increase in nuclear charge Aqueous solutions of an acid conduct electricity Because there is concentration of H+ ions and the movement of this ions helps for the flow of electrical current through the solution Hence it conduct electricity.. Acids undergo dissociation in aqueous solution to form H+ ions. When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity. |

What are the two stages in photosynthesis ?? Tell me answer ...... |
|
Answer» Thanks The\xa0process of photosynthesis\xa0occurs in two stages:Light-dependent reaction or light reaction:\tPhotosynthesis begins with the light reaction which is carried out only during the day in the presence of sunlight. In plants, the light-dependent reaction takes place in the thylakoid membranes of chloroplasts.\tThe Grana, membrane-bound sacs like structures present inside the thylakoid functions by gathering light and is called photosystems.\tThese photosystems have large complexes of pigment and proteins molecules present within the plant cells, which play the primary role during the process of light reactions of photosynthesis.The chemical equation in the light reaction of photosynthesis can be reduced to:2H2O + 2NADP+ + 3ADP + 3Pi → O2\xa0+ 2NADPH + 3ATP\xa0Light independent reaction or dark reaction\tDark reaction is also called carbon-fixing reaction.\tIt is a light-independent process in which sugar molecules are formed from the water and carbon dioxide molecules.\tThe dark reaction occurs in the stroma of the chloroplast where they utilize the NADPH and ATP products of the light reaction.\t3CO2\xa0+ 6 NADPH + 5H2O + 9ATP → G3P + 2H+ + 6 NADP+ + 9 ADP + 8 Pi |

What are the differences between the transport of minerals in xylem and phloem ?? |
|
Answer» Thanks for answering my question. Aerobic respiration Anaerobic respirationXylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food.Water is transported upwards from roots to all other plant parts. Food is transported in both upward and downward directions.Transport in xylem occurs with the help of simple physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP. Answer me if you know about this |

How are water and minerals transported in plants ?? |
|
Answer» By xylem and phylem The water from the soil reaches the leaves by the tissue called Xylem. The root hairs on the root absorb water from the soil and through osmosis the water is transported to leaves through the tissue xylem.Xylem- Fundamental tissue for transportation of waterIn plants, minerals and water are transported through the xylem cells from soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. The root cells obtain ions from the soil which creates a difference in the concentration of ions between the roots and soil. Thus, there is a continuous water movement into the xylem.Osmosis in plantsOsmosis causes osmotic pressure hence water and minerals are transported from one to another cell. Transpiration leads to a continuous water loss in addition to a suction pressure which is created due to water that is being forced into the xylem cells of the roots.Transportation from rootsWater is transported to all parts of plants through roots. The transportation takes place in the following manner\tWater through their roots is continuously absorbed by the plants. This water is sent up through the stem to all parts of the plant, including the leaves.\tOnly a little amount, of water, is retained in the plant or utilized by it in photosynthesis. The rest of it gets evaporated into the atmosphere as water vapour through the Stomata present in the epidermis of the leaves and other aerial parts of the plant.\tThis creates a suction pressure which pulls up water from the xylem of the roots to the stem and then to the leaves.\tXylem tissues are narrower in its diameter, in the form of capillary tubes (tracheids and fibres), greater will be the force.\tWhenever the xylem vessels lay empty, such as during the loss of water by transpiration, the water from below rises into them by a capillary force.Thus, it can be said that xylem plays an important role in the transportation of water and minerals once they absorb these and transport them to different plant parts.

Explain the three pathways of breakdown of glucose in living organisms ?? |
|
Answer» The process of taking in\xa0oxygen\xa0and to use it in the process of\xa0break - down\xa0of food for\xa0cellular\xa0needs is called as\xa0respiration.There\'re\xa0three\xa0pathways of breakdown of glucose in living organisms. They\'re as follows:(i) Aerobic respiration:The process of\xa0breaking down\xa0of food in the\xa0presence\xa0of oxygen to form energy is called as\xa0aerobic respiration.The\xa06 - carbon molecule, glucose is broken down into a\xa03 - carbon molecule,\xa0pyruvate. This all happens in the presence of\xa0oxygen. They by - products are\xa0Carbon dioxide,\xa0Water\xa0and\xa0Energy.(ii) Anaerobic respiration: The process of breaking down of food in the\xa0absence\xa0of oxygen to form energy is called as\xa0anaerobic respiration.During\xa0heavy exercise, our body needs more energy to continue our exercise. Here, the more\xa0oxygen\xa0is needed. But the oxygen taken by nose is\xa0insufficient.\xa0And there\'s no time to break down food in the presence of oxygen \'cause of lacking of oxygen.So, the energy produced in\xa0mitochondria\xa0in the absence of oxygen produce\xa0lactic\xa0acid\xa0which causes muscle cramps.The pyruvate is again broken down into Lactic acid which\'s also a\xa0three - carbon molecule.(iii) In mitocondria: The break down of pyruvate using oxygen takes place in\xa0mitochondria.Pyruvate is broken down to give a\xa0three - carbon molecules\xa0of\xa0Carbon dioxide.

What is low of dominant |
| Answer» Mendel\'s\xa0law of dominance\xa0states that in a heterozygote, one trait will conceal the presence of another trait for the same characteristic. Rather than both alleles contributing to a phenotype, the\xa0dominant\xa0allele will be expressed exclusively.\xa0The\xa0Law of Dominance\xa0says that when an organism is heterozygous for a trait, only the\xa0dominant\xa0allele will produce a phenotype. The first cherry is homozygous for the red allele and the second cherry is homozygous for the yellow allele. | |

What is low of segreation |
| Answer» The\xa0Law of Segregation\xa0states that alleles\xa0segregate\xa0randomly into gametes: When gametes are formed, each allele of one parent segregates randomly into the gametes, such that half of the parent\'s gametes carry each allele.\xa0Here\'s an\xa0example\xa0of the\xa0law of segregation\xa0in action: In this imaginary lumpy species, the gene for L (more lumpy) is dominant to the gene l (less lumpy). Two heterozygous lumpies with genotype Ll (meaning they have one dominant allele and one recessive allele) mate and have children. | |

What is implantatiom |
| Answer» In humans, implantation is the stage of pregnancy at which the embryo adheres to the wall of the uterus. At this stage of prenatal development, the conceptus is called a blastocyst. It is by this adhesion that the embryo receives oxygen and nutrients from the mother to be able to grow. Implantation\xa0is a\xa0process\xa0in which a developing embryo, moving as a blastocyst through a uterus, makes contact with the uterine wall and remains attached to it until birth. If the zygote\xa0implants\xa0in any area besides the uterus, the result is an ectopic pregnancy. | |

Explain different types asexual reproduction with diagram? |
|
Answer» Satyam Class notes dekh lo usme ache se hai?? Thnx aur diagram bhi chahiye sth me please send Asexual Reproduction is extremely useful as a mean of rapid multiplication. It is common in lower plants and animals.MODES OF ASEXUAL REPRODUCTION : the mode depends on the body design of the organism.1.\xa0FISSION:The parent cell divides/splits into two daughter cell-Binary Fission; splits into many cells-multiple Fission.\xa0FISSIONBinary FissionThe parents cell divides into two equal halvesEqual halves (daughter cells)E.g. Amoeba follows transverse binary fission,i.e. fissin in any plane.->Leishmania has a whip-like structure at one end and binary fission occurs in a definite orientation.Multiple FissionThe parent cell divides into many daughter cell simultaneously.Eg. Plasmodiumthe process where nucleus lengthens is NUCLEOKINESIS and where the cytoplasm lenghthens is CYTOKINESIS.2.\xa0BUDDING:\xa0A bud develops as an outgrowth on parent body due to repeated cell division at a specific site. These buds detach from the parent body when they mature.E.g. Hydra, yeast.3.\xa0SPORE FORMATION\xa0: Spores which are present in sporangia,\xa0are small, bulb like structure which are covered by thick walls that protect them until they come in contact with suitable condition. Under favourable conditions, they germinate and produce new Rhizopus indiviual.4.\xa0FRAGMENTATION\xa0: It takes place in multicellular organism with\xa0simple body organisation.It is the accidental process when the brokenpieces of an organism (fragments) grows into a complete organism.5. REGENERATION\xa0: When the simple animals like Hydra ,Planaria develop a new individual from their broken older part it is known as regeneration. It is carried out by specialised cells which divide and differentiate to form the complete individual. These cells multiply and from this mass of cells other parts are generated. Regeneration follows an organised sequence referred to as DEVELOPMENT.Vegetative PropagationA mode of reproduction in which reproduction takes place from the vegetative parts like the stem, root, leaves.Methods of Vegetative PropagationNatural1. By Roots\xa0: E.g. adventitious roots of Dahlias2.\xa0By Stems\xa0: E.g. Potato (tuber), ginger (rhizome)3.\xa0By Leaves\xa0:E.g. leaves of bryophyllum bear adventitious buds (in the notches of leaf margin) which develop into new plants.Artificial1. Grafting\xa0: E.g. Mango.2.\xa0Cutting\xa0: E.g. Rose3.\xa0Layering\xa0: E.g. Jasmine4.\xa0Tissue adture\xa0: E.g. Orchids, Ornamental Plants.Benefits of Vegetative Propagation1. Plants can bear flowers, fruits earlier than those produced from seeds.2. Growing plants like Banana, orange, rose, jasmine that have lost the capacity to produce seeds.3. Genetical similarity is maintained in the plants.4. Helps in growing seedless fruits.5. Cheaper and easier method of growing plants. |
