Answer:

True

Explanation:

Cardiac muscle cells appear striated. However, they are involuntary, unlike skeletal muscle cells, because they contract outside of human control. For example, you do not have to think about contracting your heart muscles as the already contract for you. On the other hand, skeletal muscle cells are controlled by humans as they decide which body movement to perform, such as walking or pointing.

EleoNora [17]

Answer:

convergent evolution.

Explanation:

When organisms of distantly related species or groups are found in similar environmental conditions, they develop some similar features which are otherwise not present in their ancestral species. This is called convergent evolution. Convergent evolution also results in the development of similar traits in the distantly related organisms that are found in distantly located geographical regions having similar environmental conditions. Therefore, the presence of the same features in rodents and flying squirrels represent convergent evolution.

A parent that is heterozygous for both traits (AaBb) can create how many different allele possibilities.
MAVERICK [17]
Distribute the A to the B and the b, then the a to the B and the b. You should get four different possible combinations: AB Ab aB ab. These would then be used to set up one side of a punnett square, and the other parent's genotype would be set up the same, then put on the other side of the punnett square.
