identify the explanations researchers suggested to explain differences in health and mortality by gender.

Answers

The differences in health and mortality by gender is a phenomenon for which researchers have many possible explanations.

There have been studies that have indicated that there is enough variation in the average health of males and females to conclude that there are factors at play that are affecting health.

Amongst the many possibilities, scientists have mentioned:

Gender-reliant genetic vulnerability Hormonal factorsDifferences in physiology

as the main possible reasons.

Hormones play a big part in the health of each individual and are vastly different between genders, along with the endless differences in physiology at a molecular level. These factors together may explain why some members of a gender are more vulnerable to genetic illness.

why is it important for gametes to be haploid jiskha

Answers

Answer:

its important for gametes to be haploid so when fusion of the Male and female gametes take place after fertilization the correct amount of chromosome numbers specific to the species can be restored

It is important for gametes to be haploid as just to maintain the chromosomal number. It is present for the sake of incorporation of both of the sets of chromosome in the progeny.

What is the number of chromosomes in humans ?

It is having 23 pairs of chromosomes that is having total of 46 chromosomes.

Because meiosis just  creates cells which are destined to be  the gametes  and in this reduction in the  chromosome number is just  critical that is  without the process, the union of the  two gametes  that are during  the fertilization that will result in  the offspring with just  twice of normal number of the  chromosomes.

Haploid cells in the  humans are just produced out  by meiosis. This is type of  the cell division in which the  single diploid parent cell  just divides to just  produce four with the non-identical  type of the haploid daughter cells. In  meiosis is just  used to get the type of the  produced  type of gametes and is are a  necessary kind of  precursor to  the sexual reproduction.
