Answer:
1. Mutation- enhances genetic variation
2. Selection- may raise, lower, or maintain genetic variation
3. Genetic drift- diminishes genetic variation.
4. Gene flow- could either enhance or reduce genetic variation
Explanation:
1. Mutation denotes changes in an organism's DNA. The mutations lead to new adaptive traits that evolve, which increases the genetic diversity of organisms.
2. Natural selection favors organisms best suited to their environment. Thus, selection can increase, decrease, or keep variation in a population steady.
3. Genetic drift occurs due to random events altering a population's gene pool. When this phenomenon transpires, the genetic variation within that population typically decreases.
4. Gene flow involves changes to the gene pool due to immigration and emigration. This factor can thus increase or decrease genetic variation.
Streptomycin, which is derived from certain bacteria and fungi, is utilized to combat bacterial infections (prokaryotic), including tuberculosis and mycobacterial infections. This antibiotic disrupts protein synthesis in prokaryotes as it impacts the operation of 70S ribosomes, which are essential for the production of proteins. It has no effect on eukaryotic cells since it does not attach to their ribosomes, hence leaving their protein synthesis unaffected.
The plant lost turgidity as the salt absorbed all water from the large vacuole. This resulted in its wilting appearance
The new nucleotides align correctly with those on the complementary strand
