Answer:
4 allopatric
Explanation:
The formation of a new species can occur in several ways. One such process is the separation of two populations of a species geographically. The presence of any geographical barrier may separate the two populations from each other. These populations accumulate variations over time. After several generations, the members of these two populations can not interbreed successfully and are said to be reproductively isolated. The two populations are now two different species. This is called allopatric speciation.

Biologically induced molecular oxygen (dioxygen, O2) started to accumulate in Earth's atmosphere and changed Earth's atmosphere from a weakly reducing atmosphere to an oxidizing atmosphere.
Answer:
umm hmm hope u find the answer
Explanation:
i am confused
all of the above
Algae process photosynthesis thru chloroplast which is a kind of plastid- a round oval disk-shaped body, that is involved in the synthesis and storage of food stuffs.
Chloroplasts are distinguished from other types of plastids by their green color which results from the presence of two pigments namely chlorophyll A and chlorophyll B.
A function of these pigments is to absorb light energy in plants for powering the process of photosynthesis.
