Answer: Calcium
Explanation:
The Vitamin D is an important vitamin and it is related with the element calcium in the body. The Vitamin D is responsible for the absoprtion of calcium in the body present in the food. In the deficiency or depletion of the Vitamin D in the body is likely to affect the calcium levels. The calcium is the main element present in the bones and the teeth. Calcium helps to build bones. In the condition which involves the depletion of Vitamin D levels the calcium levels will also deplete. This will result in conditions like oesteoporosis, rickets and other bone deformities.
Thus people in the northern climates receiving low sunlight, will likely to receive low Vitamin D and will likely to develop bone related problems due to low calcium levels.
Answer:
higher in saturated fatty acids
Explanation:
At the onset of a muscle contraction, the presence of calcium triggers the opening of the Na-K channels in the membrane. Potassium is a calcium inhibitor, so as the potassium flows out of the cell, it eventually reduces the presence of calcium. This causes the closure of the Na-K channel (negative feedback mechanism). In a hypokalemic state, the lack of sufficient K doesn't inhibit the calcium channel, and in turn doesn't properly terminate the muscle contraction at the cellular level.
