Answer:
The answer is mother in meiosis II
Explanation:
nondisjunction can be defined as the failure of the segregation of the child chromosomes in meiosis I and meiosis II resulting in gametogenes. This results in abnormal gametes with some chromosomal imbalance being formed and subsequent fertilization of these gametes results in a generation of abnormal individuals.
According to exercise, red-green color blindness follows an X-linked recessive pattern and the phenotype is only expressed. the father cannot bring the possibility of color blindness to his children, and the nondisjunction, defined earlier, cannot occur in either meiosis I or meiosis II. As a conclusion we can say that it may have a place in meiosis I or meiosis II corresponding to the mother and although the mother's condition may be normal, the first child would be compromised with color blindness, therefore, the mother is the carrier.

Answer:
The enzyme is<u> b. Catalase</u>
Explanation:
Catalases are ubiquitous biological catalysts or enzymes, that speed up reaction rates. Here, they mediate<u> hydrogen peroxide decomposition</u> into water and oxygen. They are essential in organisms on Earth exposed to oxygen as they protect cells from oxidative damage.
<h2>2 H2O2 -----→ 2 H2O + O2</h2>
hydrogen peroxide water + oxygen
Reactive oxygen species, or free radicals are very reactive- they can cause damage to DNA molecules, RNA and proteins, leading to cell death.
