What happens to predator populations when prey populations are scarce? Why?
GenaCL600 [577]
When prey is abundant, predator populations increase because more young are able to survive. More predators kill more prey, which, along with food scarcity, decreases the population. When prey becomes more scarce, the predator population declines until prey is again more abundant. Therefore, the two balance each other.

In humans the genetic commonality of height and skin tone is that they are both
lubasha [3.4K]

Answer:

In humans the genetic commonality of height and skin tone is that they are both <u>Polygenic Traits.</u>

Explanation:

Polygenic traits can be described as those characteristics for which there is more than one gene to determine its inheritance. The outcomes of polygenic genes result in many differentiated phenotypes. For example, the difference in height, the difference in skin colour etc.

Polygenic traits occur because one allele for a gene does not have complete dominance over the other gene. This is termed as incomplete dominance. Incomplete dominance is a Non- Mendelian trait as Mendelian traits showed one allele to be completely dominant over the other allele.

Which statement about sexual and asexual reproduction is true? *
weqwewe [10]

Answer:

The answer is A. There is more genetic variation in organisms that reproduce sexually than those that reproduce asexually.

Explanation:

This is because offspring with two parents can get genetics from both family's which means there is a chance for many different types of characteristics.

If an offspring only has one parent however, the offspring will only get those genetics from the parent which means there are not many possibilities for offspring to look or act different then their parent.

Hope this helps! Have a good day! or don't...it's up to you- <3
