Multiple alleles for a gene make populations more diverse. What are the benefits of this? Select all that apply.

A If a population encounters a new disease, some of the individuals may be immune to it.
B It helps make sure that major components of the body will stay the same.
C If a population encounters a new disease, all of the individuals will be immune to it.
D It makes it more likely that a population will survive environmental changes.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

some inherited genetic mutations can be good for the offspring, so the answer is different genetic mutations cause many forms of cancer.

1) a giant star is a star with a radius much larger than that of our sun (even hundreds of times bigger). they can be either blue giants or red giants: in the first case, the surface temperature is very high, higher than that of the sun, while in the second case the surface temperature can be lower than that of the sun. the same applies to the mass: blue giants are very massive stars, burning quickly their nuclear fuel, while red giants can have small masses (a little bit bigger than that of our sun).

2) we can find giant stars in the upper part of the hr diagram, blue giants will be on the upper left corner since they have high luminosity and high temperature, while red giants will be on the upper right corner, having high luminosity but low temperature.
