<h3><u>Answer;</u></h3>

white eyes are homozygous recessive

<h3><u>Explanation</u>;</h3>
  • <em><u>Thomas Hunt Morgan work with the fruit fly showed that genes are linked in a series on chromosomes and are responsible for identifiable, hereditary traits. </u></em>He was the first to identify that genes are linked to the same chromosome.
  • <em><u>According to his hypothesis he stated that genes that are linked are arranged linearly on a chromosome, while those genes with low combination frequencies must be closer together and thus difficult to separate</u></em>.
  • When a gene contains two similar alleles that is, either two dominant alleles or two recessive alleles then it is called homozygous dominant and homozygous recessive respectively. White eyes of a fruit fly is an example of homozygous recessive

Some students conduct an investigation in a biology lab by setting up four different artificial stomachs, each in a
Effectus [21]

Answer: D. Digestion increases as the volume of the enzyme increases.

Explanation:

Enzymes speed up reactions by reducing the activation time of a reaction. If there are more enzymes therefore, the reaction will move faster.

Pepsin is an enzyme that prefers acidic conditions so it can work with dilute HCL. It can also work in temperatures of 40 °C without getting denatured. As more Pepsin is added therefore, the reaction will move faster and digestion will increase.
