What is the difference between the sympathetic and parasympathetic division of the nervous system?.
Papessa [141]

Answer:

The sympathetic nervous system is involved in preparing the body for stress related activities; the parasympathetic nervous system is associated with returning the body to routine, day-to-day operations. The two systems have complementary functions, operating in tandem to maintain the body's homeostasis.

Genetic drift simulation: understanding evolution
sleet_krkn [62]

Answer:

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).

Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation.

Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).

Y is dominant over y.

3. Cross between two yellow squash producing plants

Genotype of parents = Yy and Yy

offspring = YY, Yy, Yy and yy,

as Y is dominant over y, so YY and Yy all produce yellow squash, and yy  produce green squash.

4. Their phenotypic ratio is 3:1 , as in question 93: 31
