Answer:

1. A producer is an organism that is capable of making its own food. For example, plants.

2. A consumer is an organism that cannot make its own food and hence fed on producers or other consumers. E.g humans

3. A predator-prey relationship is a relationship in which a predator organism eats a prey organism. For example, lion and zebra.

4.  Symbiosis is a biological interaction between organisms of different species.

5. Parasitism is a biological interaction in which one organism gains benefit and harms the other organism.

6. Commensalism is a biological interaction in which one organism gains benefit whereas the other organism neither gets harmed nor gains any benefit.

7. Mutualism is a biological interaction in which both the organisms benefit from each other.

8. A niche is the role which an organism plays in a community or an ecosystem.

1. The diagram below shows a happy family of mice, with two parents and four offspring.
Oliga [24]

Answer:

The diagram is not attached but the question can be solved with the question alone, since the necessary information was provided.

• D. Offspring D (ff EE)

Explanation:

This is a cross involving two genes in mice. The two parents mice are crossed to produce four offsprings. The genotypes of the parents mice are FFEe (black fur) and ffEe (white fur).

These two parents will produce the following allelic combinations of gametes;

FFEe- FE, Fe, FE, Fe

ffEe- fE, fe, fE, Fe

Using these gametes in a pumnet square (see attached image), 16 possible offsprings will be produced with only three (3) distinct genotypes viz:

FfEE (4/16)

FfEe (8/16)

Ffee (4/16)

Hence, based on this question, all of the offsprings except offspring D (ffEE) is likely to be produced. This means that the offspring with genotype ffEE is the imposter as the parents mice with genotypes FFEe and ffEe could not have given birth to such offspring.

Ugo [173]

Answer:

<h3>A) Enzymes are highly specific protein catalysts</h3>

Explanation:

  1. Enzymes are highly specific protein catalysts i.e. it react with only that substrate for which it has been made.
  2. Enzymes have an active site by which it binds to substrate at that specific site.
  3. Enzymes lowers the activation energy required for completion of a chemical reaction. As a result rate of the reaction increases.
  4. Enzymes never participate in a chemical reaction rather they are obtained back in its original form on the completion of the reaction.

Genetic disorders can result when sister chromatids fail to separate properly.
Firdavs [7]

Answer:

Anaphase Il of meiosis is the phase in which sister chromatids fail to separate properly from each other. It is a genetic disorder.

This nondisjunction also occurs in mitosis of cell division. It cannot pass from parents to offspring because mitosis occurs in body cells not sex cells. This nondisjunction in mitosis causes serious disease such as cancer. Cancer disease also contain abnormal number of chromosome.
