RNA stands for ribonucleic acid. It's primary function is to make ribosomes, hence the answer is 'a'
Answer:
<em>The correct option is b. the model is insufficiently labeled</em>
Explanation:
Models showing certain cycles should clearly show the reactants and the products being formed. They should be able to depict the various changes in the reactants which lead to the formation of the products.
The diagram shown in the picture is a poor depiction for the process of photosynthesis as well as cellular respiration. I does not tell us the products being formed. Like oxygen gas is released during photosynthesis but it is just labelled as gas in the diagram. The sugar being formed is also not named which is glucose.
Answer: The downstream components will be altered and ultimately affect production of glucose.
Explanation: Epinephrine is a hormone that belongs to a class of biomolecules called catecholamines. When it reaches the target cell it binds to a receptor that is connected to an enzyme called adenylate cyclase that converts ATP into cAMP(cyclic adenosine monophosphate). cAMP plays an important role in the phosphorylation of proteins which alters their activity. In this case the activity of the enzyme that hydrolyses glycogen to glucose. When caffeine blocks the activity of cAMP it ultimately inhibits the action of the downstream components.
The correct answer is the tundra.
Missing options in the question:
the gene that controls the production of stem cells
the gene that controls the production of skin cells
the gene that controls the production of red blood cells
the gene that controls the production of cardiac cells
Answer:
B. the gene that controls the production of skin cells
Explanation:
Superficial scrapes are the damages of upper skin layers which could occur due to accidents or sunburning. Upon damaging, body sheds the skin cells and then replaces with new cells. This process thus is governed by the expression of skin related genes.
