There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

Action potential propagation in a skeletal muscle fiber ceases when acetylcholine is removed from the synaptic cleft. Which of t
klasskru [66]

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.

A student wanted to know which sugar would yield the greatest amount of energy for the cell when metabolized by mitochondria. Th
Naddika [18.5K]

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
