Answer:
Prezygotic barriers:
1. Habitat isolation
2. Behavioral isolation
Explanation:
Pre-zygotic barriers are the barriers which do not allow the formation of the zygote in the organisms.
The two mechanisms of the pre-zygotic barriers are the:
1. Habitat isolation: the Flycatchers do not share the same habitat which is also mentioned in the question that they live on different islands.
2. The behavioural isolation: the Flycatchers could have evolved the different mating rituals as a result of which the could not interbreed.
Thus, Habitat isolation and Behavioral isolation are correct.
Answer:
If Jimmy works better with someone other than Joe, then Joe is a part of the problem of Jimmy getting lower grades.
b responding variable
Explanation:
If, then statements are used for scientific hypothesis's.
The correct answer is: A. Water molecules will move from Side A to Side B. The solution level on Side A will fall and the solution level on Side B will rise.
Because the barrier is permeable only for water, water will move via osmosis-down the gradient (into a area of higher solute concentration). Water tends to equalize the solute concentrations of the side A with the solute concentrations of the side B.
I believe the answer would be sedimentary rocks.
