I believe that hair and limbs are homology because all mammals have hair and similar limb structure. Hair loss and social behavior on the other hand are homolasy because not all mammals have them. Homology is the similar traits due to common ancestry while homoplasy is similar traits for other reasons other than common ancestry.

Pietro has two dogs that are related, and he wants to understand why one of the dogs has tan fur and the other has brown fur.
kompoz [17]

Polygenic inheritance is simply a form of inheritance whereby the trait of the individual or the animal is gotten from the cumulative effects of several genes. In such case, there are many genes which control the expression of the trait. This is quite different from the monogenic inheritance whereby the trait is as a result of the expression of just only one gene.

Since Pietro has two dogs that are related, and one of the dogs has tan fur and the other has brown fur, then this means there's more than one gene which is expressed in this case.

In conclusion, the answer to the question is polygenic inheritance.

Describe how each of these 4 processes can affect salinity. Are they increasing or decreasing the salinity?
Charra [1.4K]

Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.

Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.

Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.

Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.

Hope this helps!
