Answer:
Molluscs have more varied forms than any other animal phylum. They include snails, slugs and other gastropods; clams and other bivalves; squids and other cephalopods; and other lesser-known but similarly distinctive subgroups. Although it is impossible to know the subjective experience of another animal with certainty, the balance of the evidence suggests that most invertebrates do not feel pain. The evidence is most robust for insects, and, for these animals, the consensus is that they do not feel pain. In general, mollusks have 3 body regions: a head, a visceral mass, and a "foot." The head contains the sense organs and "brain," while the visceral mass contains the internal organs. Mollusks usually have a shell (although some do not). Mollusks also have an extension of the body wall called the mantle.
Explanation:
Because the moon is significantly smaller than earth,
Its gravitational pull is also smaller and weaker.
So he weighed much less on the moon than he did on earth because of the change in gravity
It is safe to assume that the eastern kingbird will have a <u>type 2 </u><u>functional response </u><u>to an increase in </u><u>prey abundance</u><u>.</u>
The functional response, in ecology, is a data-based description of the behavior of certain animals' consumption rates in response to a change in prey density. This can be of three kinds:
- Type 1: An increase in consumption
- Type 2: A decrease in consumption
- Type 3: Decreased consumption, followed by a quick increase.
The Eastern kingbird is likely to follow a <u>type 1 </u><u>functional response</u> to the presence of more prey. The reason for this, aside from it being the most common response, is that the eastern kingbird consumes insects, which do not provide a great amount of energy, in a way that consumes much energy. Therefore it is logical to assume that the kingbird will consume more prey to better sustain its rigorous feeding habits.
