Question

The basic body form of sharks has remained unchanged for over 300 million years. In contrast, the body forms of terrestrial mammals have been evolving since their radiation 65 million years ago. Which concept does this support?

Terrestrial species have a faster rate of evolution than marine species.
Some species evolve more slowly than others.
Adaptive radiation occurs when new habitats open up.
The rate at which a species evolves is random.
Species eventually reach a perfect adaptive state.

Answer 2

sooooooo hard :(

Answer 3

i think its A

Answer 4

Answer 10

From one generation to the next, a population of jellyfish changes from 64% AA, 32% Aa, 4% aa to 42% AA, 36% Aa, 22% aa. This change is an example of which type of evolutionary process?

random mating
gene flow
the Founder effect
directional selection
discontinous selection

Answer 11

what about this one @Cydney_Morgan

Answer 12

I really do not know, I would give you an answer but I do not want to jepordise your work.

Answer 13

all g

Answer 14

lets go through the options
Terrestrial species have a faster rate of evolution than marine species.
evidently land animals seem to have a greater need to evolve faster
Some species evolve more slowly than others.
yeah thats pretty evident too. the thing with evolution is that its unnecessary unless there are external features requiring a better organism a more compedative organism
Adaptive radiation occurs when new habitats open up.
nah
The rate at which a species evolves is random.
nothing is random. for example meeting a incredibly smart girl on OS who doesnt think she is smart is not random, its unique and amazing XD
Species eventually reach a perfect adaptive state.
sort of. sounds good to me. i mean humans are pretty perfect. we have the right amount of arms to help us do the stuff we need etc....but even we can evolve to be a little better
so, which do you think now?

Answer 15

hmmmmmmmm

Answer 16

either A or B

Answer 17

A is correct in this particular scenario but you cant generalise
B is generally correct always

Answer 18

so B, bro :)
