Which function of the integumentary system is illustrated in the release of sweat? A. Absorption B. Protection C. Sensory Recept
ladessa [460]

Answer:

F. Both regulation and secretion

Explanation:

Through sweat glands and superficial blood vessels, the skin is able to cool the body and regulate its internal temperature.

The eccrine sweat gland, which is controlled by the sympathetic nervous system, regulates body temperature. When internal temperature rises, the eccrine glands secrete water to the skin surface, where heat is removed by evaporation.

One parent has type A blood and the other has type B. What are their genotypes if they produced children whose blood types were
zhenek [66]

Answer:

iAiA and iBiB

Explanation:

Blood type in humans is controlled by a gene with three alleles namely: iA, iB, and i. Alleles iA and iB are dominant over allele 'i' but codominant. The following are the allelic combinations of the genotype and the resulting blood types:

iAiA or iAi - type A

iBiB or iBi - type B

iAiB - type AB

ii - type O

According to this question, one parent has type A blood and the other has type B. If all the offsprings of these parents have blood type AB, this means that the parents must have a genotype of iAiA and iBiB respectively.
