What is homogenous Sirius |
|
Answer» Homologous series is a group of organic compounds in which the successive compounds differ by CH2 group and also differ in mass by 14amu.For example : CH4 and C2H6 Mass of CH4 is 12+4=16 Mass of C2H6 is 24+6=30 Difference in mass is 30-16=14 So they belong to the same homologous series,i.e., Alkanes, as they differ by CH2 group and also differ in mass by 14amu.

Explain female reproductive organs with diagrams. |
| Answer» Female reproductive system: This system includes a pair of ovaries, a pair of oviducts, uterus and ****** opening out through urethra. Ovary: A pair of ovaries forms the gonads in female. Ovaries are the female *** organs that lie one on either side of the abdominal cavity. Ovaries by the process of oogenesis form eggs or ova which are released as one per month. Ovaries produce two hormones, namely, estrogen and progesterone.Estrogen controls the changes that occur during puberty, like feminine voice, soft skin and development of mammary glands, growth of pubic hair and controls the release of mature eggs.Progesterone controls the uterine changes during menstrual cycle, and helps in the maintenance of pregnancy.Oviducts: A tube like structure arising from each ovary on either side is called as an oviduct. This is also called as fallopian tube. The egg is carried from the ovary to the uterus through a thin oviduct also known as the fallopian tube.The two oviducts combine and open into an elastic bag-like structureknown as the uterus.Uterus:\xa0 Uterus is a hollow muscular organ which has the capacity to bear the child. It is otherwise called as womb. Zygote formed after fertilisation in the fallopian tube travels downward by dividing itself continuously to form an embryo. Embryo as it reaches the uterus gets implanted into the wall of the uterus. After fertilisation, female reproductive hormones bring in many changes to the uterus, so as to bear the growing embryo. As the embryo grows, it transforms into foetus. Uterus is the organ which bears the foetus.******: It is the reproductive part situated at the end of the uterus in female reproductive tract. It connects uterus to the outside world. ****** secretes mucous to keep the tract wet. It opens out through vulva.\xa0 | |

Explain male reproductive organs of male with diagram |
| Answer» Male reproductive system:\xa0 This system includes a pair of testis, vas deferens and a muscular organ, the *****.Testes: Testis is the main reproductive organ in males. A pair of testis is placed in a structure called as ******* which is located outside the abdominal cavity.\xa0At lower temperature maintained by the *******, testes produce sperms by the process of spermatogenesis. Sperms are the male gametes possessing a head, body and a tail. Testes also secrete male *** hormones like testosterone to regulate the development of sperms and the secondary sexual characteristicsleading to puberty.Vas deferens: Sperm duct is also known as vas deferens. They are two in number, each one arising from testis placed on either side. They transport sperms into *****. They also collect fluids secreted by different glands. These secretions are rich in proteins to enrich the sperms. Sperms along with these secretions form thick substance called as semen. Semen is conveyed to urethra through which it is discharged outside.Prostate gland and seminal vesicles secrete semen to make the movement of sperms easier.The urethra forms a common passage for both the sperm and urine as it is just one tube that connects both the glands – urinary bladder and vas deferens.*****: It is a part of male reproductive system. ***** is a muscular organ which transfers semen into female reproductive tract. ***** receives both urinary tube and sperm duct and serves as a common transporting organ for urine and semen. It opens out through a small tube called as urethra. ***** is underlined by thin blood vessels which give it continuous supply of blood. | |

Define sperm, its function and its structure. |
|
Answer» Seen xxx 1.Definition - Sperm is the male reproductive cell and is derived from the Greek word (σπέρμα) sperma (meaning "seed").2.Function - The main sperm function is to reach the ovum and fuse with it to deliver two sub-cellular structures: (i) the male pronucleus that contains the genetic material and (ii) the centrioles that are structures that help organize the microtubule cytoskeleton.3.Structure - The mammalian sperm cell can be divided in 4 parts:(i).Head: it contains the nucleus with densely coiled chromatin fibres, surrounded anteriorly by an acrosome, which contains enzymes used for penetrating the female egg. It also contains vacuoles.(ii).Neck: it contains one typical centriole and one atypical centriole such as the proximal centriole like.(iii).Midpiece: it has a central filamentous core with many mitochondria spiralled around it, used for ATP production for the journey through the female cervix, uterus and uterine tubes.(iv).tail or "flagellum": it executes the lashing movements that propel the spermatocyte.The overall structure of the sperm makes it perfectly designed to carry out its function. |

Explain the process of ultrafilteration and selectively reabsorption. |
| Answer» Ultrafiltration is a process in the kidney by which urea, salt, water and glucose etc. is extracted from the blood. When blood passes through the top of the nephron, it enters a structure called the glomerulus which is a network of tiny capillaries. This causes the pressure to increase and fluid is forced through the "sieve-like" walls of the vessels into the Bowman\'s capsule. This fluid is called the filtrate. Blood cells and larger proteins do not pass through the capillaries as they are too large and so are not found in the filtrate. A large proportion what enters the filtrate is valuable to the body and so needs to be reabsorbed into the blood. This is a process called selective reabsorption. | |

Can we burn CO² |
|
Answer» It can\'t burn CO2 cannot be burnt because if it is so then how can we use it in fire extinguisher... As we know mg burns in air and we all know that air is mixture of all gases including co2. So we say that co2 is partially burn in atmosphere. It is saturated and hence can\'t burn. It will not react with oxygen because it is already saturated with oxygen So technically, yes, you can burn carbon dioxide. But it doesn\'t burn easily and doesn\'t burn with most materials. No,No,Never. |

What are the differences between mound layering and air layering |
| Answer» Aerial layering:1. A healthy branch of the plant is selected, and a girdle is made just below a node.2. The girdle portion is covered with moist moss plants, cotton or polythene sheet to prevent evaporation of moisture.3. An earthen pot with a hole at the bottom is hung from a branch above it to ensure a continuous supply of water.4. This portion is then left undisturbed till adventitious roots appear from above the girdled area.5. When healthy roots appear through the polythene sheet, the layered shoot is separated from the mother plant.Examples: Croton, climbing rose, guava, orange, litchiGround/Mound layering:1. A branch near the ground is bent downwards so that it touches the soil.2. Under a node on the basal side, a cut is made to form a tongue.3. With the help of a small piece of wood, the two cut parts are kept apart.4. The tongue part is then covered with soil some distance from the tip.5. A stone is placed on the layered portion in position or it is covered with soil.6. Water is provided whenever required.7. After few days, the part that is under the soil develops roots. The layered part can then be separated from the parent plant and grown separately.Examples: Ipomea, rose, jasmine, mango, litchi, grapevine | |

What is the difference between fision and fusion |
|
Answer» \tFission ReactionFusion ReactionA fission reaction is splitting up of a large atom or a molecule into two or more smaller ones.Fusion is the process of combination of two or more lighter atoms or molecules into larger ones.Fission reaction doesn’t occur normally in nature.Fusion reaction process occurs in the stars, like in the sun, etc.This reaction produces highly radioactive substances.Few number of radioactive particles are developed by the process of a fusion reaction.The process requires high-speed neutrons.This process requires high-temperature, high-density environment.This process consumes a very little amount of energy to break up the atoms.High amount of energy is consumed to combine protons so that the nuclear forces can overcome the electrostatic repulsion.\t Fision means break it and fusion means join iy Fision means breaking and fusion means joining |
