Mosquitoes are cold-blooded creatures, therefore they can’t regulate their body heat and their temperature is essentially the same as their environment. Temperature and mosquito activity goes hand in hand with the insects flourishing in moist, relatively warm environments, functioning best at 80°F. Once the temperature lowers to about 60°F they become lethargic and anything below 50°F they find it hard to function at all.
After the DNA is replicated, the cell undergoes two rounds of meiosis to produce 4 cells, each wIth 23 chromosomes. This is how the cell goes from a diploid to a haploid state.
