t's HELP youUnisexual and bisexual flowers are TWO TYPES of flowers found in plants. ... The MAIN difference between unisexual and bisexual flowers is that unisexual flowers contain MALE and female reproductive organs in separate flowers whereas bisexual flowers contain both male and female reproductive organs in thesame flower.

bolic pathway:-→ Glucose is the favoured substance for respiration. All carbohydrates are USUALLY first converted into glucose before they are used for respiration→ FATS breakdown into glycerol & fatty acids. Fatty acids are degraded to acetyl CoA and enter the pathway.k→ Glycerol is converted to PGAL and enters the pathway.→ Proteins are degraded by proteases into amino acids. Each amino acid (after deamination) enters the pathway at some stage WITHIN the Krebs' cycle or even as PYRUVATE or acetyl CoA.→ The RESPIRATORY pathway is generally considered as a catabolic pathway. But it involves both anabolism and catabolism (breakdown). So it is better called as an amphibolic pathway.Example:- Fatty acids breakdown to acetyl CoA before entering the respiratory pathway. But when the organism needs to synthesise fatty acids, acetyl CoA withdraw from the respiratory pathway.Similarly, during breakdown and synthesis of protein, respiratory intermediates are involved.

presence of a large number of plants and animals.Forests are said to be bio diversity hot spots.They are of critical importance because 50% of known vascular plant SPECIES and 42% of land animal species are located in these highly diverse hot spots or MEGA diversity Zones.Among the 25 hot spots of the world, two are found in India namely, Western Ghats and the Eastern Himalayas.These two areas are rich in flowering plants, reptiles,amphibians,butterflies and some mammals.How these hot spots maintain ecological balance ?Reasons are listed below :1. FOREST is a habitat for the various living organisms.2. Maintains water cycle.3. Prevents SOIL erosion.4. Forest are called as LUNGS of earth, as they give fresh Oxygen and take Carbon dioxide.5.Helps in maintenance of Food chain.6.Regulates temperature.7.Provides various things like Timber,wood, medicinal plants etc which meets our daily needs.Hope it helps:)

is the process of PHYSICAL changes through which a child's BODY MATURES into an adult body which is CAPABLE of sexual REPRODUCTION.

Oogenesis ?Oogenesis is the process of the formation of a mature ovum from the oogonia in females. It takes place in the ovaries. During oogenesis, a diploid oogonium or egg MOTHER cell increases in size and gets transformed into a diploid primary oocyte. This diploid primary oocyte undergoes first meiotic division i.e., meiosis I or reductional division to form two unequal haploid cells. The smaller cell is known as the first polar body, while the larger cell is known as the secondary oocyte. This secondary oocyte undergoes second meiotic division i.e., meiosis II or equational division and gives rise to a second polar body and an ovum. Hence, in the process of oogenesis, a diploid oogonium produces a single haploid ovum while two or three polar bodies are produced.The three stages of Oogenesis :-Stage # 1. Multiplication Phase:The primordial germinal cells divide repeatedly to form the oogonia. The oogonia multiply by the mitotic divisions and form the primary oocytes which pass through the growth phase.Stage # 2. Growth Phase:The growth phase of the oogenesis is comparatively longer than the growth phase of the spermatogenesis. In the growth phase, the size of the primary oocyte increases enormously.In the primary oocyte, large amount of fats and proteins becomes accumulated in the form of yolk and due to its heavy weight (or gravity), it is usually concentrated towards the lower portion of the egg forming the vegetative pole.The cytoplasm of the oocyte becomes rich in RNA, DNA, ATP and enzymes. Moreover, the mitochondria, Golgi apparatus, ribosomes, ETC., become concentrated in the cytoplasm of the oocyte.During the growth phase, TREMENDOUS changes also occur in the nucleus of the primary oocyte. The nucleus becomes large due to the increased amount of the nucleoplasm and is called germinal vesicle.The chromosomes change their shape and become giant lamp-brush chromosomes which are directly related with increased transcription of messenger RNA (mRNA) molecules and active protein synthesis in the cytoplasm. When the growth of the cytoplasm and nucleus of the primary oocyte is completed, it becomes ready for maturation phase.Stage # 3. Maturation Phase:The maturation phase is accompanied by the maturation or meiotic division. The maturation division of the primary oocyte differs greatly from the maturation division of the spermatocyte. Here after the meiotic division of the nucleus, the cytoplasm of the oocyte divides unequally to form a single large-sized haploid egg and three SMALL haploid polar bodies or polocytes at the end.This type of unequal division has the great significance for the egg. If the equal divisions of the primary oocyte might have been resulted, the stored food amount would have been distributed equally to the four DAUGHTER cells and which might prove insufficient for the developing embryo.Therefore, these unequal divisions allow one cell out of the four daughter cells to contain most of the cytoplasm and reserve food material which is sufficient for the developing embryo.hope it helps must.plz mark me as a brainlist..plz plz plz

n :-How do human activities affect nitrogen CYCLE?_____________________Answer :-Human activities like burning fossil fuels release a lot of greenhouse gases like NITRIC oxide in the air.This LEADS to acid rain and changes the uneven nitrogen balance.Also the same nitric oxide REACTS with water to form nitric acid.Nitrogen dioxide is another compound FORMED by human activities .Nitrogen compounds are also released on research and other human activities of industrialisation.This affects the nitrogen cycle.SHORTEST ANSWER :Human activities like burning fossil fuels release a lot of greenhouse gases like nitric oxide in the air.This affects the nitrogen cycle.Hope it helps !___________________________________________________________________

ne Layer The Ozone layer is the layer of the atmosphere containing large amount of ozone and it helps to PROTECT the Earth from the harmful ultraviolet radiations.It is present in the stratosphere of the atmosphere.Steps taken : The steps are taken to prevent damage of ozone are to stop the usage of Ozone depleting substances ( ODS ) because they are responsible for chemically reacting with Ozone and changing it.⇒ ODS include CHLOROFLUOROCARBONS ( CFC s ) . These are organic compounds released from refrigerators , air conditioners , etc.⇒ So , the alternatives of the CFC s  should be usedThese are the necessary steps other than USING alternatives :▶ Organizing international treaties ( EG : Montreal Protocol ) to control ozone depletion▶ Restriction in the use of A.Cs .▶ Control of TRADE of the Ozone depleting substances .▶ Control in the production of the Ozone depleting substances.

your answer What is the difference between food chain and food web?!What is your question?Food Chains:Food chain is a model that SHOWS flow of energy and nutrients from one organism to another organism in an ecosystem. The length of a food chain depends upon the number of organisms. It STARTS from producer species such as tress or grass and ending at apex predator species such as grizzly bears or killer whales; detrivores such as earthworms or woodlice; or decomposer species like fungi or bacteria. A food also shows the relation between organisms as who they are related with each other by the food they eat. Plants and animals requires some type of food for survival. Plant produce their own found via photosynthesis process. Since they produce their own food they are called and producers while those organisms which do not produce their own food like animals and humans are known as consumers.Food Web:Food web or food cycle is the connection between food chains and what species eats what in an ECOLOGICAL system. Food web also known as consumer-resource system. Most communities in food web include various populations of producer organisms which are EATEN by any number of consumer populations. For example, the green crab is a consumer and decomposer. In food web, producers are eaten by many different consumers, and most consumers onward are eaten by more than one predator. For example, a squirrel eats seeds, fruits, and nuts. The squirrel man be eaten by a fox or a raccoon. Fox also eats mice and grasshoppers , etc. Most organisms are part of several food chains. A food web starts with the producers in ecosystem and then branches off into interconnected food chains that show who eats whom in ecosystem.Differences:Following are the main differences between food chain and food web.Food chain is a single linear pathway through which food energy and nutrients travels in the ecosystem while food web is number of interconnected food chains through which energy and nutrients travels in the ecosystem.In food chains, usually member of high trophic level feed upon a single type of organism of lower trophic level while in food web members of higher trophic level feed upon many organisms of lower trophic level.In food chains, SEPARATE and isolated food chains increases the instability of the ecosystem. In food web, stability of the ecosystem increases by the presence of complex food webs.Food chains have no effect on improving the adaptability and competitiveness of the organisms while more complex food webs improves the adaptability and competitiveness of the organisms

re autotrophs produce food through a process calledchemosynthesis, RATHER than through photosynthesis. Autotrophs that perform chemosynthesis do not USE energy from the sun to produce food. Instead, they make food USING energy from chemical reactions, often COMBINING hydrogen sulfide or methane with oxygen.
