Motile sperm in fungi, plants, and animals depend upon to drive the microtubule interaction in their flagella. a. adp b. atp c. nadph d. sucrose

b. ATP

Explanation:

ATP is an acronym used to indicate the adenosine triphosphate molecule (Adenosine TriPhosphate). This molecule is the main form of chemical energy since its hydrolysis is highly exergonic. This means that by undergoing the hydrolysis process (fission by water action), this molecule releases a large amount of free energy.

ATP is essential for the functioning of all living organisms, basically this molecule participates in any mechanism of metabolism, not only in humans, but in any living creature. An example of this is that motile sperm in fungi, plants, and animals depend upon ATP to drive the microtubule interaction in their flagella.

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents

explanation:

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
