Tom [10]

Answer:

The correct answer is - 4. ttPp

Explanation:

Given - tall is dominant over short pea plant

let assume T is dominant and t is short which is recessive

Similarly, P for dominant purple flower and p for white flower

The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:

    P   P

p   Pp Pp

p   Pp Pp

This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant

Thus, the correct answer is ttPp

In the absence of oxygen, a yeast cell undergoes fermentation and uses 100 molecules of glucose. How much net ATP will be genera
vredina [299]

Answer:

200 ATP molecules

Explanation:

Yeast is a fungus that undergoes fermentation instead of cellular respiration when there is an absence of oxygen. In the fermentation process undergone by yeast, which produces an alcohol as product (alcohol fermentation), two (2) ATP molecules are produced as net ATP.

However, if a yeast cell undergoes fermentation and uses 100 molecules of glucose, the yeast cell will generate a net ATP of 2 × 100 molecules = 200 molecules.
