Answer:
<h2><u>
directional selection</u></h2>
Explanation:
This type of natural selection is referred to as . In this type of natural selection, either one phenotype is preferred or the other; therefore, there is no equilibrium between the populations of the phenotypes that are present.
Examples of organisms that have undergone directional selection are black bears during the ice ages, African chichlid and sockey salmon.
Answer:
Chemiosmosis is the use of energy created by H+ moving through ATP synthase down a concentration gradient. this energy is then used to phosphorylate an ADP to become ATP
Explanation:
Answer:
it can be a disadvantage to population because it produces many offsprings which can lead to high increase in population.
Answer:
C. They can grow to larger populations more quickly
Explanation:
Bacteria are the <u>key entities</u> of <u>biogeochemical cycle</u>s (Nitrogen, Carbon, Oxygen, etc.) on Earth. The strength of these cycles is typically achieved when they can multiply faster in a relatively <u>short time period</u>. If all bacteria on Earth start reproducing via sexual means only, then many of the biogeochemical cycles would take forever, thus <u>generating nutrients at a slower rate</u>. Since higher organisms (e.g. eukaryotes) depend on the abundant supply of nutrients, the overall life on Earth would be compromised to a larger extent in the absence of sufficient nutrients supply. Thus, it is <u>beneficial for all forms of life that bacteria reproduce mainly via asexual means</u>.
PS: A simple bacterium can produce millions of copies in 24 hours period.
