Answer:
Migratory birds play a critical role in the ecosystem, pollinating plants, dispersing seeds, and consuming insects and small mammals. ... Migration conditions appear to impact both annual survival and the timing of breeding, which in turn strongly predicts annual productivity within this population of migratory birds..
Explanation:
The answer is that they have traits that enabled them to survive in a changing environment.
During the evolution of the Earth, and later during the evolution of life, the environment was not constant. Change in the environment could lead to an extinction of some species. But, some species were able to adapt or could tolerate a wide range of environmental factors. One of the explanation, why unicellular organisms did not evolve into complex multicellular organisms is because they have traits that help them to tolerate the wide range of factors, and thus, survive in changing environment.
Below are the options:
Having two phases of meiosis allow for more unique cells to be produced.
Meiosis is a form of asexual reproduction which leads to more genetic variation.
Meiosis produces 4 haploid daughter cells which all contain identical DNA segments.
<span>Crossing over during metaphase allows segments of DNA from 2 parents to SWAP and produce non-identical haploid cells.

The answer <span>Meiosis is a form of asexual reproduction which leads to more genetic variation</span>
Hello there,
They transfer the energy with or without medium (MATTER)
Since radiation is transferred through wave, it does not need any form of objects to pass through.
For example, the heat that radiation through the sun could be felt without any objects that connect us from The sun itself.
I don't know answer to this question, but I can explain what it wants for you to name, if that would helped you.
It says that you have to find 4 doings of bacterias (micro-organisms) in the organ system for digestion.
