Answer:
The correct answer is ''high survival rates of offspring and the cost of parental care''
Explanation:
Natural selection is the differential reproduction of some genetic variants with respect to others. Natural selection favors individuals who maximize their total reproductive success throughout life, that is, it favors certain phenotypes or variants are associated with greater offspring and / or greater survival, that also means that selection will favor those who stop spending on a particular breed at the right time to invest in another, that is, the amount of energy invested in each of them. This same natural selection also favors those genes that make it effective when the body that carries them is in development to extract all possible parental investment from their parents.

Answer and Explanation:
Digestion of carbohydrates occurs in the mouth, duodenum and small intestines. In the mouth, salivary amylase hydrolyses starch to maltose. In the duodenum, pancreatic amylase breaks down starch into maltose. In the small intestines, enzyme maltase digests maltose to glucose.
Answer:
The correct answer is D. The surface of the skin can be mapped into distinct regions, each served by a single spinal nerve: these regions are called dermatomes.
Explanation:
A dermatome is the area of skin innervated by a single spinal nerve and its spinal ganglion. The cutaneous nerves are those that reach the skin, picking up the sensitivity of the skin. Each cutaneous nerve is distributed in a certain area of skin, called a dermatome.
A pair of posterior or sensory roots and a pair of anterior or motor roots arise from each cord segment, joining laterally at the level of the intervertebral foramen to form a mixed spinal nerve. Each of these innervates a strip of skin called a dermatome, so the body surface can be considered a true mosaic of these.
In the extremities the arrangement of dermatomes is more complicated because of the embryological rotation of the limbs as they grow from the trunk.
Due to divergent evolution, some species may have similar anatomical structures with the same purposes. The species while not exactly similar are close enough to allow the interbreeding of the two, such as the horse and mule
