Answer:
How physiological mechanisms serve as the basis for hunger
Explanation:
Physiological mechanisms are able to provide explanations to body functions, events and outcomes. Such mechanisms could be altered voluntarily when there's the need to. Hunger is on example of such. When a person is hungry the muscles of the stomach contracts and messages are sent to the brain. This process is what tells the person thaat he needs to feed.
Hemophilia is an inherited bleeding disorder where clotting factors are either absent or present in low amounts. As a result, the blood doesn't clot. It is an X-linked recessive trait that is inherited.
<h3>What is X- linked recessive genetic illness?</h3>
Genetic abnormalities known as -X-linked recessive genetic illnesses are brought on by an atypical gene on the X chromosome. "Carriers" for a disease are females who have the disease gene on one of their X chromosomes. The fact that carrier females have a second copy of the gene to make up for the copy with the disease-causing alteration or mutation usually prevents them from showing symptoms of the ailment.
A male has one X chromosome, thus if he gets an X chromosome that carries a gene that causes a disease, the condition will manifest in him. Male X-linked If the other X chromosome from their mother is healthy, all of their daughters will carry the illness gene.

Answer:
3
Explanation:
Male ; EeHh
Female ; EeHh
Then,
possible gametes for each = EH / Eh / eH / eh
where,
EH Eh eH eh
EH EEHH EEHh EeHH EeHh
<em> One eye One eye One eye One eye</em>
<em> One horn One horn One horn One horn</em>
<em />
Eh EEHh EEhh EeHh Eehh
<em>One eye </em><em>One eye</em><em> One eye </em><em>One eye</em><em> </em>
<em>One horn </em><em>Two horn</em><em> One horn </em><em>Two horn</em>
eH EeHH EeHh eeHH eeHh
<em>One eye One eye </em><u><em>Two eye</em></u><em> </em><u><em>Two eye </em></u>
<em>One horn One horn </em><u><em>One horn</em></u><em> </em><u><em>One horn</em></u><em> </em>
eh EeHh Eehh eeHh eehh
<em>One eye </em><em> One eye </em><em> </em><u><em>Two eye</em></u><em> </em><u><em> Two eye </em></u>
<em> One horn </em><em>Two horn </em><em> </em><u><em>One horn</em></u><em> </em><u><em>Two horn </em></u>
<u><em /></u>
Therefore,
One eye, one horn:One eye, two horn:<u>Two eye, one horn</u>:Two eye,two horn
is,
9 : 3 : <em><u>3 </u></em>: 1
This ration proves that the above working is correct and is dihybrid cross.
<em>the function of epidermis is to protect the leaf
make it air tight
prevent water loss as it is waxy
also it is transparent and allows all light to enter...
chloroplast is required for carrying out process of photosynthesis...
as epidermis is not specialized to carry out photosynthesis... so it does not have any chloroplast...</em>
energy enters an ecosystem through photosynthesis. By feeding on plants and on one another, animals play an important role in the movement of the matter/energy though. they also influence the quantity of plant and biomass present. so the anwser is D, secondary consumers to tertiary consumers
