Answer:
In the scenario given above, Elodea Canadensis which produces extremely high amount of oxygen is used in raising fishes placed in a tank. This oxygen is needed for easier living in the tank. <em>In a situation whereby the Elondea Canadensis is not present in the tank, the fish would struggle to leave comfortably in the tank. with time, the water will become clouded with carbon-dioxide. This would lead to the fish dying due to lack of oxygen.</em>

Explanation:
Gametes with two heterozygous copies of a chromosome may result from nondisjunction in either meiotic division.
<h3>What three types of nondisjunction are there?</h3>
Nondisjunction can take one of three different forms: failing to separate a homologous pair of chromosomes during meiosis I; failing to separate sister chromatids during meiosis II; or failing to separate sister chromatids during mitosis.
<h3>How can you tell whether nondisjunction takes place in meiosis 1 or 2?</h3>
- Nondisjunction, which can lead to an aberrant amount of chromosome-bearing gametes, can happen during meiosis I and meiosis II.
- The primary distinction between nondisjunction in meiosis 1 and 2 is that whereas sister chromatids fail to separate in meiosis II, homologous chromosomes fail to separate during meiosis 1.
<h3>What are mitotic and meiotic divisions?</h3>
- Mitosis and meiosis are the two distinct processes of cell division.
- When people talk about "cell division," they typically mean mitosis, which is the process of creating new cells for the body.
- The cell division process known as meiosis is what produces egg and sperm cells. A vital process for life is mitosis.
