Gametes are only found in males
Gametes have double the chromosomes
Gametes do not go through call division
Gametes go through meiosis
The Correct Answer is D
A. Gametes are only found in males: This statement is incorrect; gametes (sperm and eggs) are found in both males and females.
B. Gametes have double the chromosomes: This is incorrect; gametes are haploid (having half the number of chromosomes), while somatic cells are diploid (having two sets of chromosomes).
C. Gametes do not go through cell division: Gametes are produced through meiosis, which is a type of cell division.
D. Gametes go through meiosis: Gametes are produced through meiosis, a specialized form of cell division that reduces the chromosome number by half, allowing for sexual reproduction.

Correct Answer is C
Explanation
A. Pons: The pons is involved in regulating the rate and depth of breathing but is not the primary site affected by pyrogens for temperature regulation.
B. Cerebral cortex: The cerebral cortex is responsible for higher-order functions like reasoning and sensory perception but does not directly regulate body temperature in response to pyrogens.
C. Hypothalamus: The hypothalamus acts as the body’s thermostat and is directly affected by pyrogens, leading to the elevation of body temperature (fever) as part of the immune response.
D. Amygdala: The amygdala is primarily involved in emotion regulation and does not play a direct role in temperature regulation.
