Answer:

Genetic variation as it is an important factor causes evolution by increasing or decreasing the frequency of alleles in a particular population through the process of natural selection.

On the basis of knowledge about genetic variation, we can conclude that-

1st example -  Increase in gene pool of zebra.

2nd example - Decrease in gene pool of trees.

3rd example - Increase  the gene pool of snakes.

4th example - Decrease  of gene pool of buffalo.

A zebra migrates to join a different herd of zebras.

    This would lead to biodiversity in the new zebra herd.

Competition for sunlight leads to taller trees.

    Taller trees would prosper, and shorter trees would die out. Trees would continuously evolve to be larger.

The DNA of a snake changes to make its venom stronger.

    This mutation created biodiversity and favoritism in natural selection. The trait will more likely be passed on.

A grassfire randomly sweeps through a population of buffalo and kills most of the animals.

    Only the strongest Buffalo survived, decreasing competition strengthening the gene pool.

You are working with yeast cells, and you discover an inhibitor of one of the enzymes necessary
lesya [120]

Adding the inhibitor to the yeast cells in the petri dish would likely cause an increase oxygen usage by the cell.

HOW DO YEAST RESPIRE?

  • Yeast are unicellular organisms that belong to the kingdom Fungi. Yeasts are capable of respiring anaerobically i.e. can respire without oxygen.

  • Yeast can, however, respire both aerobically and anaerobically. Yeast undergoes an anaerobic respiration called FERMENTATION, which is used to produce ethanol (alcohol) from pyruvate (product of glycolysis).

  • If a substance that inhibits the conversion of pyruvate to ethanol is added to yeast cells growing in a petri dish, the process of fermentation will be inhibited. Hence, the yeast cells will have to switch to aerobic respiration and make use of oxygen.

Therefore, adding the inhibitor to the yeast cells in the petri dish would likely cause an increase oxygen usage by the cell.
