I think binary fission<span />
Here, you have a case of codominance.
You know that because they tell you that in the presence of both alleles (purple and white) you have a light violet. No one is dominant over the other, both appear as a combination of alleles.
Purple: P
White W
A heterozygous plant has PW alleles.
PW x PW = PP PW WP WW
25% chances of PP (deep purple)
50% chances of PW (ligth violet)
25% chances of WW (white)
Cyanobacteria were important for Earth's early atmosphere because they produce oxygen.
<u>Explanation</u>:
Cyanobacteria is a Phylum consists of the free living bacteria and endosymbiosis. Cyanobacteria is also called blue green algae which obtain energy through oxygenic photosynthesis and releases Oxygen gas in the atmosphere. Cyanobacteria is responsible for the early oxygen production in environment which changed the early reducing atmosphere of the earth into the oxidizing atmosphere that causes the event of great oxygenation that is rusting of the earth. During this period most of the anaerobes extinct or evolve to live as a parasite or symbol on in other hosts.

Explanation:
If the graph line comes lowers from 1999 to 2013 so it means that steps taken by the EPA and the factories were effective in reducing air pollution. The steps taken by the EPA and the factories were effective in reducing air pollution occurs from two pollutants i. e nitrogen oxides (NOx) and sulfur dioxide (SO2) if they install chimneys which collect these gases and reduce pollution. if the factories uses coal having less concentration of sulphur so less air pollution occurs.
