Correct statement: After death blood settles in the lowest parts of the body. The blood coagulates and remains in those parts of the body even if it is later moved. These purple marks are lividity.

Explanation:

Lividity, also known as livor mortis, is the process through which the body´s blood stops moving after death, as the heart stops beating.  The blood begins to settle, by gravity, to the lowest parts of the body, and even if the body is moved, coagulated blood remains there. The lowest parts are those body regions that are in contact with a surface or the ground at the moment of death.  At this point, the deceased individual gets pale, and the lividity area gets purple or reddish-purple.

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

the answer is "a.) well–developed vascular system."
