DDT was one of the first chemicals in widespread use as a pesticide. Following World War II, it was promoted as a wonder-chemical, the simple solution to pest problems large and small. Today, nearly 40 years after DDT was banned in the U.S., we continue to live with its long-lasting effects:
Answer:
Dentritivore
Explanation:
Dentritivores are heterotrophs that depend on other organisms to derive their nutrients from by feeding on their dead remains as well as consuming their feces. Dentritivores play an important role in the recycling of nutrients in an ecosystem and can be found almost at all trophic levels of the ecosystem. Dentritivores can be referred to as “bottom-feeders” in which in an aquatic habitat, most of them are found on the seabed. Other examples aside the vampire squid, include crabs, lobsters, sea stars.
Option D has the highest concentration of lactic acid in the student's muscle tissue.
We can arrive at this answer because:
- Lactic acid increases its concentrations in the muscle due to a high physical effort in anaerobic conditions.
- This promotes a lack of oxygenation in the muscle, which through contractions, causes the cell to partially catabolize glucose molecules.
- The result of this is the creation of two pyruvic acid molecules, which will react with NADH2 molecules, creating lactic acid, which will build up in the muscle as the exercise continues.
As we can see in the information presented above, option D shows the performance of flexions with more intensity and for a longer period, which justifies a greater accumulation of lactic acid in the muscle.
It is important to remember that the accumulation of lactic acid in the muscle is a negative situation and that it can cause muscle pain and fatigue.

One of the most common cause of hypersecretion of the endocrine glands would be tumors. Specifically, the presence a hormone secreting endocrine-cell tumor. Hypersecretion is when the gland is secreting too much of a hormone. Hope this helps.
