Answer:
The correct answer is d the positive feed back reduces change in the the system
Explanation:
In an biochemical reaction when the released product stimulate the release and activation of the same product and act together to exibit their biological function, then this type of regulation is called positive feedback.
The positive feed back mechanism leads to increased change in the system that"s why it is named so.

Each set of 3 nucleotides, called a codon, within DNA codes for a specific protein to be constructed. Including enzymes
Stem cells of the animals are the most similar to the meristematic cells of the plant.
<u>Explanation:</u>
- Meristematic cells are the most important cells for the plant which give rise to the various tissues and plant organs. These meristematic cells are capable to undergo cell division and they are called totipotent.
- The stem cells of animals and humans are capable of doing the function by replacing the new cells for growth and development.
- The difference among these two tissues is that meristematic is capable to produce total organs whereas stem cells are capable to produce only specific tissues.
