If a fat source is counted towards an individual's discretionary calories, what does this mean? a. This fat source should account for 30% of the daily fat intake.

b. This fat source supplies essential fatty acids.

c. This fat source can be consumed in great quantity with no adverse health effects.

d. This fat source is high in saturated fat and its intake should be limited.

e. This fat source should be a consistent part of a person's diet.

The correct answer is D. This fat source is high in saturated fat and its intake should be limited.

Explanation:

In nutrition, the term "discretionary calories" refers to extra calories that are not part of nutritional requirements but can be consumed sporadically. In the case of fat sources, this includes foods such as cheese, butter, or fried foods that contain high levels of fat, especially saturated fat, which contributes to heart disease and other conditions. Due to this, these types of food are consumed as part of "discretionary calories", which means their intake is not essential and should be limited. Thus, if a fat source is counted towards discretionary calories it means it should not be consumed daily but its intake should be limited because it contains saturated fat (Option D).

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.
