Answer:
True
Explanation:
Meiosis is a type of cell division that occurs in gametic cells. In this cell division, one cell is divided into four cells and the chromosome number is reduced to half therefore it is also called reduction division.
During meiosis crossing over occurs between homologous chromosomes that allow the exchange of genetic material between them that results in the formation of genetically unique daughter cells.
In spermatogenesis during the first meiosis division, the homologous chromosomes get separated into two daughter cells reducing the chromosome number by half and during second meiotic division sister chromatids separate into two more cells. Therefore four genetically different cells are generated.

Errors can occur when the chromosomes segregate into the gametes during meiosis resulting in egg or sperm with too many or too few chromosomes. As a result, fertilised eggs and the ensuing embryos may have trisomy (an extra chromosome of a particular pair) in each cell or monosomy (one chromosome fewer in each cell).
Herbivore; carnivore
A rabbit is an example of a herbivore while a hyena is an example of a carnivore.
A herbivore is an animal that obtain its energy by feeding mainly on plants (i.e. that eats no meat). Other examples of herbivores apart from rabbit are cows, sheep and insects. A carnivore is an animal that feeds on meat as the main parts of its diet. Other examples of carnivores apart from hyena are lions, coyotes, tigers and eagles.
Answer: c. regulates the secretory activity of the pituitary gland.
Explanation:
The hypothalamus can be defined as a small part of the brain that is located at the base of the brain. It has two functions in the human body, first releasing hormones and maintaining homeostasis.
The hypothalamus is responsible for linking the endocrine system to the brain through the pituitary gland. It stimulates the secretion and inhibition of the hormones from the anterior pituitary.
