Answer:
The answer is A - The populations will not be able to interbreed because they are different species and different species cannot interbreed
Explanation:
The population of birds become reproductively isolated because they are different species and different species are unable to interbreed. This is as a result of barriers which are called mechanisms of reproductive isolation which involves mechanisms, behaviors and processes that are critical for speciation. In reproductive isolation the different species are able to live in the same are but their properties and characteristics do not allow them interbreed to produce healthy and sterile offspring.
Answer:
<em>The correct option is A) an increase in oxygen levels, which led to the extinction of many anaerobic organisms.</em>
Explanation:
Photosynthesis can be described as a process in which food (glucose) is produced by photosynthetic organisms by using carbon dioxide, water along with light energy from the sun. Oxygen is released as a by-product of this reaction. The process of photosynthesis initially allowed for oxygen gas to get accumulated in the air. This caused the rise of aerobic organisms who required oxygen for respiration. Before the photosynthesis organisms evolved, there was not enough oxygen gas on earth to support the life of aerobic organisms.
1: I believe is B.
2: I believe is True
3: I believe is D.
4: I believe is D.
5: I'm not completely sure about this one, because it depends on the substance. Rocks molecules don't move because the object is solid, no matter how cold or hot the rock is. But if I were to guess, I would say True.
6: I believe is A.
7: I believe is B.
8: I believe is False.
9: I believe is False.
10: I believe is C.
11: I believe is False.
12: I believe is C.
13: I believe is A.
14: I believe is A.
I really hope I got all of these correct. Hope this helped!
