Explanation: a life-sustaining element, from the atmosphere and oceans into organisms and back again to the atmosphere and oceans. ... Scientists are currently looking into ways in which humans can use other, non-carbon containing fuels for energy.
Homozygous tall pea plant has allele (TT)
Heterozygous tall pea plant has allel (Tt)
If we cross the two tea plants the genotypes produced are
TT x Tt
TT, Tt, TT, Tt
<span>The correct answer should be B. The overuse of antibiotics. Since antibiotics as their name says kill biotics, that is, they fight against bacteria, they were used a lot and bacteria started developing resistance to them which is a common thing. Since it's difficult to find new types and the trials last long, new diseases are emerging faster than we can create medicine for them.</span>
<span>In the particular
order from
top to bottom , the answers are;</span>
<span>Genetic drift</span>
Gene flow
<span>Natural Selection </span>
<span>Gene flow occurs
during migration where alleles from one population
are introduced to another population hence increasing the population diversity. </span>
Genetic<span> drift occurs when the allelic frequency of a population changes due factors such as calamities and emigration or natural selection.</span>
<span>Natural selection is the force of ‘survival for the
fittest’ that is applied differentially on the population
by nature. </span>
CELL REPRODUCTON: many organelles are involved in cell reproduction, including the nucleus and the mitochondria and chloroplasts. All of these organelles contain DNA that must be replicated so that each new cell will have complete copies.
