Answer:
The correct answer would be - three chromosomes.
Explanation:
Meiosis is the type of cell division that takes place in only sex cells and called reduction division as a single parent cell divide into four daughter cell that contains a half number of chromosomes as the parent cell.
The daughter cells are always haploid and have the half number of chromosomes. If an organism has 2n number of in its parent sex cell the daughter cells after meiosis will have n number of chromosomes
Therefore, mosquito = 2n = 6
after meiosis = n = 6/2 = 3
Thus, the correct answer would be - 3 chromosomes.
Answer:
C) Olfactory bulb is a correct answer.
Explanation:
Olfactory blub role it to sense the smell once they receive the information from the olfactory receptor, it sends the information from the nose to the brain region.This process occurs when the odorants get bind to the olfactory receptors at the specific sites and the glomerulus is present on the olfactory bulb of brain region detects the signal from the receptor and transmit to olfactory blub, and then the brain interacts with the sensory parts, by this ways smell identification is done.
The areas of the brain located just above the sinus cavity and just below the frontal lobes that receive information from the olfactory receptor cells is known as the Olfactory bulb.
