Sarin is a toxic substance that irreversibly inhibits the enzyme responsible for degrading acetylcholine (acetylcholinesterase).
sasho [114]

Answer:

option D. continuous muscle spasms and convulsions

Explanation:

Sarin is an organophosphorus synthetic compound and is highly toxic. Sarin toxic is colorless and odorless. It act as a potent nerve agent and used as a chemical weapon. This toxic substance binds irreversibly with the enzyme acetylcholinesterase.  This enzyme is responsible for degrading acetylcholine. The toxin interferes with the normal functioning mechanism of nervous system.

The organism poisoned by sarin could suffer paralysis,  vomiting, continuous muscle spasms and convulsions. Thus, option D is correct.

11. The arrows on the left and right sides of Figure 1 show the effects of one species on the species that are on
daser333 [38]

The image related to that question is attached below.

In the figure, we can see that on the left side, sea otters are very influential in the population of sea creatures, if the killer whales are not in the environment. That's because sea otters are strong predators of sea urchins. However, sea urchins are not as influential in the size of the seaweed population, providing little effect on that population. This is because sea otters control the population of sea urchins through predation. Thus, if more sea urchins are consumed by sea otters, the sea urchin population becomes small and consequently the consumption of algae (by sea urchins) is small.

On the right side of the figure, killer whales are great predators of sea otters and establish a strong predatorism, being very influential in the population of sea otters. This predatorism causes the otter population to decrease and stay in controlled and limited sizes. In this case, with few sea otters in the environment, their predatorism in relation to sea urchins is less, allowing the sea urchin population to grow and to consume more seaweed, providing a strong impact on the seaweed population.
