3 is the answer.
Binary fission is a type of asexual reproduction and is the most common method of reproduction in prokaryotes. It may occur in some unicellular (single- celled) eukaryotes..
Eukaryotes use sexual recombination during reproduction to create or generate genetic variation and thus the resulting offspring will have a mixture of the parents' genetic characteristics.
Prokaryotes on the other hand will simply produce clones of themeslves through binary fisson. After the process of replicating its own genetic material, the prokaryote simply divides into two daughter cells that are almost identical in size and that concludes the process.
Answer:
c. pituitary gland
Explanation:
The hypo(below) thalamus is an almond size structure located superiorly to the brainstem. it is located below the thalamus. Hence the name hypothalamus.
It is primary function is is to control the body homeostatic functions of sleeping and waking up, sex, thirst and hunger etc.
It performs these roles by serving as the primary link of the nervous system with the endocrine system. Pituitary gland is an example of endocrine gland that secrets many hormones. (they are called endocrine because the hormones are secreted directly into the blood streams.
<u>Its activities are controlled by the nervous stimulation from hypothalamus. Therefore the instructions to secretes certain hormones to the post and anterior part of the pituitary gland depends on the hypothalamus.</u>
Growth hormones, oestrogen, and thyroid are examples of hormones of the pituitary glands.

Answer:
alleles-one of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome.
dominant- The dominant allele of the gene is inherently dominant,so it hides the presence of the recessive allele
heterozygous-having two different alleles of a particular gene or genes.
homozygous-a particular gene that has identical alleles on both homologous chromosomes
recessive-A recessive gene is a gene that can be masked by a dominant gene
