Answer:

Calcium ions

Explanation:

This is because the contraction of skeletal muscle occurs as a result of the release of Calcium ions from internal stores which is a result of the function of a neural signal.

So, skeletal muscles contract when calcium ions are released. There is also an action potential which is generated which causes the muscle to contract. This action potential is present in both skeletal muscle cells and neurons and is as a result of the movement of sodium ions in neurons and calcium ions in skeletal muscle cells.

A person is told to take 1.25 mg of vitamin d daily. how many 0.125-mg tablets should this person take?
vovikov84 [41]
This is a simple calculation involving drug doses.

The solution is as follows:

(0.125 mg/tablet)(n) = 1.25 mg
n = (1.25 mg)/(0.125 mg/tablet)
n = 10 tablets

So a person needs to take ten 0.125 mg tablets of vitamin D to have that 1.25 mg dose.

Which of the following factors affects population growth independent of population density?
ch4aika [34]

Answer:

Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.

Explanation:

In a population at its carrying capacity, there are as many organisms of that species as the habitat can support. If resources are being used faster than they are being replenished, then the species has exceeded its carrying capacity. If this occurs, the population will then decrease in size.
