Answer:
Relaxation of the dartos muscle.
Explanation:
Testes are present in scrotum outside the pelvic cavity to maintain the temperature about 2-3 degrees Celsius below the body temperature as required for sperm production. Dartos muscle is the layer of smooth muscle located in the superficial fascia. The contraction of dartos muscle serves to make the skin of the scrotum wrinkled and tight.
During hot weather, the dartos muscle relaxes and makes the surface of scrotum less wrinkled to increase the loss of the heat from its surface. The increased heat loss from the surface of scrotum due to relaxed dartos muscles keeps the testes protected from heat.
<span>A physician may be virtuous (kind, just, and honest) and still not know which actions are known as morally permissible.
There are more ways to define "morally permissible." One is to break the words apart, to define "morally" and then "permissible." However, there is a more holistic way. In Ethics in the First Person, Deni Elliott defines permissibility thusly. Permitted [means] behavior that is within the bounds of the moral system.</span>
Answer:
The nucleus.
Explanation:
The nucleus functions like the brain in humans.
The answer is
Let's first represent alleles:
R - a dominant allele for round seeds,
r - a recessive allele for wrinkled seeds,
Y - a dominant allele for yellow seeds,
<span>y - a recessive allele for green seeds.
</span>
The cross will look like this RRYY x rryy
So, all of the offspring will be heterozygotes (RrYy) with round seeds (Rr), yellow seeds (Yy).
