Meiosis is a process of reductional division in which the amount of genetic material is reduced. Gametogenesis is the process of the formation of gametes. Gametes produced by organisms are haploids (containing only one set of chromosomes), while the body of an organism is diploid. Therefore, for producing haploid gametes (gametogenesis), the germ cells of an organism undergo meiosis. During the process, the meiocytes of an organism undergo two successive nuclear and cell divisions with a single cycle of DNA replication to form the haploid gametes.

The method of arranging organisms into groups on the basis of similarities and differences is called classification. Evolution on the other hand refers to a slow, gradual and continuous process by which the previously existing organisms develop into existing living organisms.

Total parasitic plantsare the heterotrophicplantswhich completely depends on the hostplantfor their all requirements include shelter, water, food. They are achlorophyllus so they are unable to prepare their own food. Best example is Cuscuta and is complete stemparasite.

Partially parasitic plants are also called as hemiparasitic plants. These are partially parasitic as they depend on the host plants for nourishment under some conditions. Sometimes, they perform photosynthesis in order to obtain nourishment. In these conditions, partially parasitic plant obtains water and minerals from the host and synthesises its own food. e.g. Nuytsia floribunda, Rhinanthus.

Carbon fuels such as wood, coal, petroleum release unburnt carbon particles in the environment. These particles are very dangerous pollutants and cause respiratory diseases for example asthma.When fuels are incompletely burnt, they release carbon monoxide gas into the atmosphere. This gas is very dangerous as it is poisonous in nature. If we burn coal in a closed room, then the person sleeping in that room will be killed by the action of carbon monoxide.The combustion of fossil fuels also releases a large amount of carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas which is responsible for global warming. Global warming is a rise in the overall temperature of earth’s surface. This leads to melting of polar caps and rise in the sea level and further results in flooding of coastal regions.Burning of coal and diesel releases sulphur dioxide gas. This gas is extremely corrosive and suffocating in nature. Petrol gives off oxides of nitrogen. The oxides of sulfur and nitrogen get dissolved in rainwater and form acids. This is known as acid rain. This water is very harmful to plants, animals, and various monuments

Amoebatakes infoodusing temporary finger-like extensions of the cell surface which fuse over thefoodparticle forming afood-vacuole as shown in figure. Inside thefoodvacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm.

Amoebaobtainsits foodby the process of endocytosis. It engulfs thefoodparticle with the help of pseudopodia and then forms a vacuole around it. When the particle is completely trapped theamoebasecretes digestive enzymes that digests thefood. thus theamoebaobtains it'sfood.

Tapeworms have no digestive tract so they must eat food already digested by another animal. That is precisely what they do as a parasite inside our intestines. Tapeworms absorb nutrients directly across their skin (cuticle). They also reproduce inside us. There are many species of tapeworms, not all can infest humans.

Ans :- Organ and tissue-specific manifestation refer to the areas where microorganisms affect either a certain organ or a certain tissue or cell in a person's body.

Organ-specific manifestation is when the microorganisms affect a whole organ of one, for example, the lungs or kidney.

Tissue-specific operation refers to the time when a microorganism affects just a cell or tissue of an organ.

i need more points for only tissue specific manifestations..

Tissue-specific manifestation refers to the time when a microorganism affects just a cell or tissue of an organ.

When a microbe infects the tissues of the body of an individual in a particular type of disease, it is termed as tissue specific manifestation.

For example, in HIV the virus infects the tissue and cells of the organism making decreasing his/her immunity.

Transcription is the first step ingene expression, in which information from ageneis used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, ortranscript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.

Transcriptionis the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.

Transcription is performed by enzymes calledRNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).

Transcription has three stages: initiation, elongation, and termination.

Small segments of DNA aretranscribedinto RNA by the enzyme RNA polymerase, which achieves this copying… Duringtranscription, only one strand of DNA is usually copied. ... The activetranscriptionof agenedepends on the need for the activity of that particulargenein a specific cell or tissue or at a given time.

Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Another good example of convection is in the atmosphere. The earth's surface is warmed by the sun, the warm air rises and cool air moves in.

Areolar connective tissue is made of cells and extracellular matrix ("extra-" means "outside", so the extracellular matrix is material that is outside of the cells). The matrix has two components, fibers and ground substance.Areolar tissue is found in many locations around the body.

One important area is the skin (areolar tissue is found in both the dermis and sub-cutaneous layers of the skin - see diagram). The areolar tissue located in the skin binds the outer layers of the skin to the muscles beneath.

Areolar tissue is also found in or around mucous membranes, and around blood vessels, nerves, and the organs of the body.Areolar Connective TissueThese tissues are widely distributed and serve as a universal packing material between other tissues. The functions of areolar connective tissue include the support and binding of other tissues.

It also helps in defending against infection. When a body region is inflamed, the areolar tissue in the area soaks up the excess fluid as a sponge and the affected area swells and becomes puffy, a condition called edema.

(a) Mendel demonstrated that traits can be either dominant or recessive through his monohybrid cross. He crossed true-breeding tall (TT) and dwarf (tt) pea plants. The seeds formed after fertilisation were grown and the plants that were formed represent the first filial or F1 generation. All the F1 plants obtained were tall. Then, Mendel self-pollinated the F1 plants and observed that all plants obtained in the F2 generation were not tall. Instead, one-fourth of the F2 plants were short. From this experiment, Mendel concluded that the F1 tall plants were not true breeding; they were carrying traits of both short height and tall height. They appeared tall only because the tall trait was dominant over the dwarf trait. This shows that traits may be dominant or recessive.

(b) Mendel demonstrated that traits are inherited independently through his dihybrid cross. He considered two traits at a time, seed colour and seed shape in which yellow colour (YY) and round shape (RR) are dominant over green colour (yy) and wrinkled shape (rr), respectively. Mendel observed that the F2 progeny of dihybrid cross had a phenotypic ratio of 9 : 3 : 3 : 1 and produced nine plants with round yellow seeds, three plants with round green seeds, three plants with wrinkled yellow seeds and one plant with wrinkled green seeds. In this experiment, he found that round yellow and wrinkled green are parental combinations whereas round green and wrinkled yellow are new combinations. In a dihybrid cross between two plants having round yellow (RRYY) and wrinkled green seeds (rryy), four types of gametes (RY, Ry, rY, ry ) are produced. Each of these gametes segregate independently of each other and each has a frequency of 25% of the total gametes produced. From this experiment, he concluded that when two pairs of traits are combined together in a hybrid, one pair of character segregates independent of the other pair of character. This is known as the law of independent assortment.

Glucoseis a common nutrient that is absorbed in the small intestine and reabsorbed by the kidney tubules.

Glucoseis a monosaccharide obtained by the digestion ofcarbohydratesin the small intestine. It is one of the most important sources of energy in the life forms.

INTRODUCTION: Budding is a type of asexual reproduction seen in yeast,hydra etc.before budding,a soft zone appears in the cell wall of vegetative cells..Small buds will bulge out from this zone .At this stage,nucleus of the cell undergoes a mitotic division .one of the daughter nuclei will be pushed into the bud..A constriction is formed between the vegetative and the bud,which can grow in to yeast cells.

thank you

The Yeast under high power of the microscope look like chain of buds.

Most yeasts reproduce asexually by asymmetric division process called budding First it produces a small protuberance on the parent cell that grows to a full size and forms a bud . this bud detaches from the mother body by forming a constriction at the base . Then budding is repeated to form chain of buds.

Option (d) is correct.

Binomial nomenclatureisimportantbecause In this, each organism given a name containing genus and species which is constant all over the world. It is easy to identify and describe any organism by this name without any confusion. e.g, Mangifera indica is scientific name which is constant in all over world.

Binomial names areuniversally accepted. Theyavoid confusionas each plant has only one binomial name.

These names arescientific, precise and avoid repetition.

These names aresimple and meaningful.

Binomial nomenclatureindicates relationships.

Binomial nomenclature("two-term naming system"), also calledbinominal nomenclature("two-name naming system") orbinary nomenclature, is a formal system of namingspeciesof living things by giving each a name composed of two parts, both of which useLatin grammatical forms, although they can be based on words from other languages. Such a name is called abinomial name(which may be shortened to just "binomial"), abinomen,binominal nameor ascientific name; more informally it is also called aLatin name.

The first part of the name – thegeneric name– identifies thegenusto which the species belongs, while the second part – thespecific nameorspecific epithet– identifies the species within the genus. For example, humans belong to the genusHomoand within this genus to the speciesHomo sapiens.Tyrannosaurus rexis probably the most widely known binomial.[1]Theformalintroduction of this system of naming species is credited toCarl Linnaeus, effectively beginning with his workSpecies Plantarumin 1753.[2]ButGaspard Bauhin, in as early as 1622, had introduced in his bookPinax theatri botanici(English,Illustrated exposition of plants) many names of genera that were later adopted by Linnaeus.[3]

The application of binomial nomenclature is now governed by various internationally agreed codes of rules, of which the two most important are theInternational Code of Zoological Nomenclature(ICZN) for animals and theInternational Code of Nomenclature for algae, fungi, and plants(ICNafp). Although the general principles underlying binomial nomenclature are common to these two codes, there are some differences, both in the terminology they use and in their precise rules.

In modern usage, the first letter of the first part of the name, the genus, is always capitalized in writing, while that of the second part is not, even when derived from aproper nounsuch as the name of a person or place. Similarly, both parts are italicized when a binomial name occurs in normal text (or underlined in handwriting). Thus the binomial name of the annual phlox (named after botanistThomas Drummond) is now written asPhlox drummondii.

In scientific works, theauthorityfor a binomial name is usually given, at least when it is first mentioned, and the date of publication may be specified.

Inzoology"Patella vulgataLinnaeus, 1758". The name "Linnaeus" tells the reader who it was that first published a description and name for this species of limpet; 1758 is the date of the publication in which the original description can be found (in this case the 10th edition of the bookSystema Naturae)."Passer domesticus(Linnaeus, 1758)". The original name given by Linnaeus wasFringilla domestica; the parentheses indicate that the species is now considered to belong in a different genus. The ICZN does not require that the name of the person who changed the genus be given, nor the date on which the change was made, although nomenclatorial catalogs usually include such information.Inbotany"Amaranthus retroflexusL."– "L." is the standard abbreviation used in botany for "Linnaeus"."Hyacinthoides italica(L.) Rothm."– Linnaeus first named this bluebell speciesScilla italica; Rothmaler transferred it to the genusHyacinthoides; theICNafpdoes not require that the dates of either publication be specified.

Binomial Nomenclature was formly introduced by Swedish scientist Carl Linnaeus. In the binomial Nomenclature two terms are used to denote a species of living organisms, the first one indicate the genus and second one the specific epithet. Example: Homo sapiens is the scientific name of human.
