these are options for the first !

1:

a) natural selection

b) genetic mutation

c) comparative anatomy

2:

a) homologous structures

b) analogous structures

c) vestigial structures

Natural selection - we can resume this to the selection of the best adapted individuals, whose traits will be passed on until we have a fully adapted species.

Image 1.2 -

Homologous structure - in biology we use this term to refer to organs in different animals that are in a similar position or have a similar structure.

Answers:

A and A.

I'm sure that options A and E are incorrect. Option "B" is quite complex and doesn't really explain anything we want to know. Option "D" is probably a trick-option, since I don't think it occurs in fungi, only in pine cones. Therefore, the option is spore. Fungi, when they reproduce sexually or asexually they produce spores.

C.

This should be a very easy question to answer. Sharks can breathe underwater, since they have gills, which means they don't need to surface to breathe.

Whales, in the other hand, do not breathe underwater, and therefore do not have gills.

Gills.

Humans and mice are more similar to each other (they're closer in the phylogenic chart). Kangaroos and platypus are indeed more similar to each other (they're also closer in the phylogenic chart). All of the animals in the phylogenic chart share a common ancestor (otherwise we could not make a phylogenic chart).

Answers:

A, B and C.

If there is a higher decrease in soft, small seeds, which are the food of finches with small beaks, these finches will have less food and their population will decrease.

Since there was a drought and the drought did affect the vegetation, this damage might be irreversible, and therefore, finches with large beaks will go better off.

Also, since there was a decrease in soft seeds, there will be more room for large seeds to grow, which means finches with large beaks will have more food and their population will increase.

Answers:

A and C.
