Answer:
The correct answer is - B.directional selection.
Explanation:
When a bacterial colony is exposed to an antibiotic the maximum number of the bacteria dies due to noo resistane and some of survive even with no or very less resistance to the antibiotic and reproduce.
Over many generations the survived and continuosuly divivng resitant bacteria become more and more with higher frequency and ultimately evolved to a resistance strain of the bacteria for the antibiotic. Such mutation is directional selection as the frequency of the resistance bacteria going from no resistance to a high amount of resistance is unidirectional and progresive.
Answer:
a. Glycolysis
b. actually, both plants and animals use glycolysis. They use these during cellular respiration and plant respiration
c. Heart tissue!
Explanation:
a. Glycolysis produces 2 ATP per glucose molecule, and thus provides a direct means of producing energy in the absence of oxygen. Lactic acid, the end product of anaerobic glycolysis.
b. In organisms that perform cellular respiration, glycolysis is the first stage of this process. In plants, this metabolic process occurs in the cytosol and plastids of both photosynthetic and non-photosynthetic organs.
c. Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. In highly oxidative tissue, such as the heart, the production of pyruvate is essential for acetyl-CoA synthesis and L-malate synthesis.

Answer:
hmm I'd say something like "Solar and Wind energy systems are renewable sources and ultimately are healthier for the planet, the drawback is that other resources (i.e oil and coal) tend to be cheaper"
The answer is anticodon.
Anticodons are base triplets on transfer RNA (tRNA). t<span>RNA carries amino acids to the ribosome for protein synthesis. </span>The prefix<em> anti-</em> suggests that anticodons are complementary to the codons on mRNA. Codons are base triplets on mRNA. So, anticodons of tRNA pair with codons of mRNA in the process of protein synthesis.
