Answer:

The 'gene' which causes (inherited, red and green types of) colour blindness is found only on the X chromosome. So, for a male to be colour blind the colour blindness 'gene' only has to appear on his X chromosome. For a female to be colour blind it must be present on both of her X chromosomes.

A population of lizards lives in a rocky area next to a desert. Some lizards are light colored and blend into the sand. Others a
hjlf

Answer:

c. They may evolve into two separate species as a result of disruptive selection

Explanation:

Disruptive selection is a type of natural selection wherein some extreme change in the surroundings favor two distinct phenotypes while trimming off the mean. Here, the environmental conditions favor more than one phenotype. In the given example, disruptive selection would favor the light-colored lizards in the sandy region while the dark-colored would be favored in rocky regions due to their respective survival success.

With time, these two populations would accumulate more variations and reproductive isolation would not allow them to interbreed and thereby two distinct species of lizards would evolve.

Predict how changing the grass population will affect the other organisms at first. Write + for “Increase” or – “Decrease” next
Afina-wow [57]

Answer: Here you go!

Explanation:

Doubling the amount of grass would definitely increase the rabbit population since there is more food/resources for it to produce. Since the food chain has a domino effect everything else would go up as well because of the increase of food/resources that will help sustain the population of all. so for the first line it would be increase for rabbit snake and hawk. Halving the amount of grass would effect the population of all animals as well. But in a more negative way. It would decrease because the rabbits wouldn't have enough food to produce and thrive. With the decline of rabbits less snakes will live because of the low amount of their main food source. Same with the eagles. So therefore it would be decrease in all the bottom lines.
