Plants also have structures that help them survive. Plants have different parts, like roots, stems, leaves, flowers, and fruit. These structures help them survive. Other plants have flowers that are the perfect shape for insects to visit and help with pollination. Some plants have really long roots that help the plant gather water from deep below the surface of the Earth. Plants that live in really dry areas, like a desert, have special leaves.

Due to resource partitioning, zebra relative density changes over time and grass height.
<h3>What is resource partitioning?</h3>
- Resource partitioning is the process by which due to natural selection, competing species use different resources and niches.
- In the case of African savanna, right after peak rain all the three grazers (zebra, wildebeest, and Thomson’s gazelle) have high density.
- After rain in one month relative density of zebras is maximum but it becomes nearly zero after three months due to high density of wildebeest and then increases a little after six months.
- The density of zebras is greatest when the grass is tallest and most abundant because of resource partitioning as zebras get the most out of eating tall grass.
- Zebras can eat and digest faster taller grasses with many stems.
- This gives them an advantage over other grazers in terms of nutrition when the grass is tall.

Answer:
Allele frequency is a measure of the relative frequency of an allele on a genetic locus in a population. Usually it is expressed as a proportion or a percentage. In population genetics, allele frequencies show the genetic diversity of a species population or equivalently the richness of its gene pool.
Answer:
d. Competitive inhibition will decrease because the proportion of the active sites occupied by substrate will increase.
Explanation:
Enzymes are bio catalysts in living cells responsible for aiding biochemical reactions.
Their active sites are primary protein 3D structure for binding with substrates during reactions.
Enzymes reactions are usually affected by inhibitors(e.g methyl alcohol) which compete with the active site with the actual substrate(ethyl alcohol) ,
This is an example of competitive inhibition. The more ethyl alcohol available, the more active sites occupied, therefore denying the inhibitor methylalchol chances to the active site, thus preventing the formation of toxic formaldehyde, and more of non toxic substances from formation of more ADH-METHYL ALCOHOL COMPLEXES at the active sites
