One right sized substrate (key) fits into the active site (key hole) of the enzyme (lock).
<span>Reticulocytes are immature red blood cells.
Red blood cells that haven't fully developed, yet.
When our bodies lose a large amount of blood,
we rapidly produce reticulocytes,
so that our bodies can quickly replenish their red blood supplies.
And obviously, when we donate blood, we lose blood.</span>
Answer:
The deep sea environment is more stable and is less impacted by detrimental events and phenomena such as changes in temperature changes and intense storms.
Explanation:
In 2018, researchers analyzed over 200 species inhabiting in both deep sea and near the sea surface across the world and found that <u>deep sea organisms are more likely to have longer lifespans.</u>
According to their results, the environmental conditions that characterize the deep sea is more stable, enabling deep-dwelling organisms to have longer lifespans. Moreover, deep sea organisms are more protected from events and phenomena that affect shallow-water species, such as changes in temperature and intense storms.
The answer is A because the heat for the copper is 0.38 and the iron is 0.45 so the copper heats the food faster than the iron
