Rickets is the disease in children in which an inefficient mineralization of the bone forming tissue causes deformities. This condition results in weak or soft bones in children, normally due to an extreme and prolonged deficiency of vitamin D. Vitamin D promotes the absorption of calcium and phosphorus from the gastrointestinal tract. The symptoms include bowed legs, stunted growth, bone pain, large forehead, and trouble sleeping among others.

The spontaneous action potential established in cardiac contractile cells is highly dependent on which of the following? A. The
Arada [10]

Answer:

E. All of the above

Explanation:

In cardiac contractile cells there is rapid depolarization, then a plateau phase and repolarization.

when an action potential stimulates the cell, voltage-gated channels open quickly commencing the positive-feedback mechanism of depolarization. This in turn raises the membrane potential to approximately +30 mV, and this closes the sodium channels. Next comes the plateau phase, where membrane potential declines relatively slowly due to the opening of the slow Ca2+ channels, allowing Ca2+ to enter the cell while few K+ channels are open, leading to K+ to exit. Once the membrane potential reaches approximately zero, the Ca2+ channels close and K+ channels open, allowing the exit of K+. The repolarization lasts approximately for a while and here is when the membrane potential drops until it reaches resting levels once more and repeats the cycle.

5. Studying light from a star allows us to… a. determine a star's temperature b. determine what elements the star is made of c.
Basile [38]

Answer:

The correct answer is option C "determine how a star is moving (toward, away, fast, slow)"

Explanation:

All realized components emanate and assimilate specific frequencies of light, which is important for the electromagnetic range. By considering the frequencies of light (as demonstrated by 'lines' inside the electromagnetic range) discharged by an object in space, astronomers can get a scope of information.

One thing they look at is the adjustment in situation of lines in the range from a star this can tell astronomers the distance away the star is, regardless of whether it is moving towards or away from us and how quick it is moving.
