Answer:
Mitochondria and Chloroplast
Explanation:
Because the mitochondria is the power house
Answer:
Option A, It makes them less dense than water, thus aiding in buoyancy
Explanation:
Lipids stored with in the body of planktons make them capable to float in water against the buoyancy force of water in the down ward direction by reducing the overall density of the planktons. Hence, option A is correct
Answer:
21
Explanation:
Amino acids are the basic structural units of proteins. Our bodies contain 21 amino acids it uses to make all proteins, although books recognize only 20 amino acids. The 20 amino acids are the alphabet of proteins.
Answer:
b) the human form of hexokinase.
Explanation:
According to the given information, the amino acid sequences of bacterial and human hexokinase enzyme are different. When a human hexokinase gene sequence is introduced into a mutant bacteria that lack its own hexokinase gene sequence, the resulting bacteria will produce the human form of hexokinase. This is due to the fact that the introduced sequence was from the human hexokinase gene.
Promoters serve as binding sites for RNA polymerase to facilitate gene transcription. Therefore, the presence of a normal bacteria promoter would allow the transcription of the human hexokinase gene in the mutant bacteria.
