Consider two very distantly related species, Species A and Species B. These species live in distinct but similar environments an
never [62]

Answer:

convergent evolution

Explanation:

If we have two species that share a similar trait or look alike a lot, but they live in places isolated from each other, and they only have a very distant relation, then it is a case of convergent evolution. This type of evolution occurs with species that are not closely related, but they live in environments where having the same or very similar traits is advantageous. This can often lead to a confusion when looking at the species only on the outside, and it can be very misleading. As an example we can take the sabretoothed predators that existed in the past. Both the smiloden and the thylacosmilus had large saber like teeth, and even their bodies looked very similar, so one would assume that they are closely related, but that was not the case. The smilodon was part of the cat family, while the thylacosmilus was a marsupial, making them very distantly related. They developed same same and some very similar traits because their environment created the evolutionary pressure for those traits to develop as they were advantageous, despite them evolving in totally different places and separately.

Which of these statements describes some aspect of facilitated diffusion?a.Facilitated diffusion is another name for osmosis.b.F
frosja888 [35]

Answer:

D

Explanation:

Facilitated diffusion is a form of passive transport hence no energy is required by the cell. This means that while the molecules are moving down a concentration gradient – line normal diffusion – the movement of the molecules needs to be facilitated (in this case by a transmembrane protein) either because the molecule is polar and can't pass through the hydrophobic region of the cell membrane, or the molecule is too big to passively pass through the small natural pores of the cell membrane.

N a pond, tadpoles eat algae and fish eat the tadpoles. around the pond, grasshoppers eat grass and, at night, are preyed upon b
Dima020 [189]
I believe that in this community the tadpoles are: the primary consumers. A n ecological community is the set of all populations of all species found in a given place. Primary consumers are mainly herbivores which feed on plants; which are the primary producers of all the energy in an ecosystem. In this case the tadpoles eat algae (primary producer) thus they are primary consumer.
