Question

consider the following claim about how a snail leech can increase its reproductive success: covering its eggs with its body increases the chances that the leechs eggs will hatch. which of the following observations best supports the claim? most leeches do not move anywhere while they are covering their eggs. water snails that live in freshwater streams often try to eat leech eggs. leech eggs are eaten less often when they are covered by the leeches.

Explanation:

The claim is that covering eggs with body increases hatching chances. If eggs are eaten less often when covered, it implies better - survival conditions for eggs, which supports the idea that covering them helps with hatching and thus increases reproductive success. The first option about leeches not moving doesn't directly relate to egg - hatching chances, and the second option about water snails trying to eat eggs just shows a threat but not the effectiveness of the covering behavior.

Answer:

Leech eggs are eaten less often when they are covered by the leeches.
