The answer is when levels of the amino acid are high, it binds to the repressor, ending the synthesis of this amino acid
Answer:
Answer is bile
Cholecystokinin is secreted by cells of the upper small intestine. Its secretion is stimulated by the introduction of hydrochloric acid, amino acids, or fatty acids into the stomach or duodenum. Cholecystokinin stimulates the gallbladder to contract and release stored bile into the intestine.
They are made of non-renewable resources. The resources that they are made of also are unsustainable
Answer:
Cross-bridges would form in the absence of an action potential from a motor neuron.
Explanation:
The injected calcium ions would bind to troponin. Troponin would make tropomyosin move away from the myosin-binding sites on actin. The presence of free binding sites on the actin would be followed by the contraction cycle. This would include hydrolysis of ATP to energize myosin heads and binding of these heads to actin to form cross-bridges. Therefore, cross-bridge formation would occur without any action potential if calcium ions are injected directly into the muscle.
Answer:
The correct option is <em>Both Cell A&D.</em>
Explanation:
The diagram in the picture shows how a cell (A) undergoes the process of replication and produces a cell (B) containing one full set of double chromosomes.
Then, the cell undergoes the process of mitosis to produce two daughter cells (C & D).
Mitosis can be described as a method of asexual reproduction in which the daughter cells produced are identical to the parent cells and are also identical to each other. Hence, the genetic content of the cell C will be the same as the genetic content of cells A & D.
