Answer:
The correct answer is- hormone signal amplification
Explanation:
The signals that are received by the cell can be amplified in the cell which results in the production of more than one molecule of the product. There is a signal pathway in every cell and the longer the signal pathway the more amplification chances are there.
For example, one membrane receptor is able to produce 10 secondary messengers and each secondary messenger generates 10 mRNA transcript so here the signal amplified by 1000 folds.
So in this question, it is seen that a small amount of releasing factor causing the release of a much greater amount of cortisol which shows the example of hormone signal amplification.
All plants have chlorophyll-a which blocks(reflects) green light and absorbs red and blue wavelengths. It seems like it would be more efficient for plants to absorb green light since energy is most powerful from the sun through green wavelengths. However, the chlorophyll-a in chloroplasts actually defend the plant from harmful damage of the TREMENDOUS amount of power from the sun transmitted in green wavelengths.
SO CHLOROPHYLL-A PROTECTS PLANTS FROM TOO MUCH ENERGY IN GREEN LIGHT.
Answer:
b. where movement occurs through arm-over-arm swinging.
Explanation:
Brachiation is a form of locomotion observed in some species of animal that are adapted to arboreal (tree living) life.
<em>This type of locomotion involves the swinging of arms and the suspension of the body to move from trees to trees.</em>
Animals that exhibit brachiation usually have modified body structure with long forelimbs/hook-like fingers and a highly mobile shoulder joints. Examples of such animals include gibbons and siamangs.
The correct option is b.
When a child has celiac<span> disease<span>, his body has a major problem with </span>gluten. Damage is done to the lining of his small intestine when any food containing gluten –are ingested. </span>
<span>It is a lifelong condition where there is no known medicine to cure, although a happy and normal life is said to be possible with proper management. The only treatment to follow is a gluten-free diet. Gluten includes wheat, barley, and rye which is nearly impossible to completely remove from a child’s diet. Parents need to be aware also of hygiene products especially when bathing young children.</span>
