A couple has been trying to conceive a child for 12 months. They decide to consult a doctor about their inability to conceive. After several tests, the doctor suggests that perhaps they will need to use because of a low sperm count.

an assisted reproductive Technology.

Explanation:

This is the infertility corrective procedures, which involve the removal of the sex-cells of both male and female, the  fusion,(fertilization) of these, outside  the body  (in-vitro  fertilization), or isolation of a single sperm and fussing it with an ovum(intracytoplasmic sperm injection) to form  the zygote, and the implantation of the zygote back into the uterus, for the normal development  to embryo  and fetus.

This  procedure  may also involve the use of the Donor's egg or sperm, or frozen sex cells . Sometimes  If the  woman egg cells  are not receptive, the zygote can be  formed from her  husband  sperm, and carried  by another contracted woman called surrogate mother.However, if the zygote is formed from a  donor's egg the contracted woman is called a gestational mother.

Generally factors such as age, legal procedures of each country, physiology of the couples, emotional status, religion, complications in the child physiology, are some of the factors that may affect the efficiency of this procedure. Non the less this medical procedures has saved many marriages and made many couple happy.

a motor homunculus represents a map of brain areas dedicated to motor processing for different anatomical divisions of the body.

homunculus represents the importance of various parts of your body as seen by your brain. as a result, they take up a lot of brain space. although the cortical homunculus is a curiosity, penfield's work in mapping the brain's relationship to the body was invaluable.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
