Answer:
The eukaryotic cell nucleus. Visible in this diagram are the ribosome-studded double membranes of the nuclear envelope, the DNA (complexed as chromatin), and the nucleolus. Within the cell nucleus is a viscous liquid called nucleoplasm, similar to the cytoplasm found outside the nucleus.
Answer:
a) Acetylcholine is degraded by acetylcholinesterase.
Explanation:
After it binds for its receptor on the plasma membrane of the postsynaptic cell, acetylcholine must be removed in order to prevent repeated stimulation. Acetylcholinesterase is enzyme for the inactivation of acetylcholine, present at all cholinergic synapses. This enzyme hydrolyses acetylcholine and breaks it to the acetate and choline. Choline can be reused for the synthesis of the new acetylcholine molecule so it is taken back into the presynaptic cell.
Answer:
A possible hypothesis would be:
IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria
Explanation:
The hypothesis is a testable explanation aimed at providing a theoretical explanation to a question. The hypothesis is a predictive statement about the possible solution, which can be tested. A hypothesis must be testable via experimentation. It often has an IF, THEN format.
Hence, in the case experiment where a student wanted to know which sugar (maltose, glucose or sucrose) would yield the greatest amount of energy for the cell when metabolized by mitochondria. A possible hypothesis of this experiment will be that: IF a yeast cell is supplied with maltose sugar, THEN it would yield the greatest amount of energy when metabolized by bacteria
Note that, this hypothesis must be testable by conducting an experiment and it doesn't have to be true. It can be disproved or proved by the outcome of the experiment. In this case, the hypothesis is giving an educated guess that maltose is the sugar that will yield the greatest amount of energy for yeast cells
I think the answer is B, that most amino acids are encoded by more than one codon.
