Nearly all of the energy that drives an ecosystem comes from the sun in the form of solar energy. Solar energy enters the ecosystem through a process of photosynthesis that is the starting point for all forms of plant and animal life on the planet. The sun and solar energy are the beginning source of energy for almost all functioning ecosystems and organisms on the planet.
Answer:
Cellular respiration
Explanation:
photosynthesis: carbon dioxide———> glucose, oxygen
cellular respiration: glucose, oxygen——>carbon dioxide
<span>The ability to taste PTC is due to the presence of at least one dominant allele for the PTC taste gene, so a nontaster genotype should be homozygous recessive(pp). If the frequency of pp is 45%, then frequency of p would be:
pp=0.45
p= </span>√0.45
p=67%
p+P= 100%
P= 100%- p
P= 100%-67%= 33%
<span>The number of North American population that has is homozygous dominant(PP) genotype would be:
P=33%
PP= 33%^2= 10.89% = 0.1089 = 0.11</span>
