People with diseases that result in the malabsorption of which nutrient are at risk for a vitamin d deficiency?
grigory [225]

Inadequate dietary vitamin D or its deficiency leads to malabsorption of calcium. Nutritional disorder leads to the rare disease rickets, which causes bones to become soft and bend in children. In adults, vitamin D deficiency leads to osteomalacia, which causes weak bones, bone pain and muscle weakness.

The body needs vitamin D to properly absorb calcium and phosphorus from the diet. However, keeping the right quantities of calcium and phosphorus in bones is challenging when vitamin D levels are low.

The two sources of vitamin D are-

  • Natural sunlight
  • Foods such as fish oil, Egg yolk and fatty fishes like salmon and mackerel

There are other disease conditions which lead to poor absorption of vitamin D-

  • Inflammatory bowel disease
  • Celiac diseases
  • Kidney problems

Rzqust [24]

The answer would be B:The data suggests that exercise increases the rate of cellular respiration because more carbon dioxide was produced.


The data has a consistently show that the time needed to change BTB color in after exercise group is much shorter(less than half) compared to before exercise group. If the time needed longer, this show that the amount carbon dioxide removed from the lungs is much higher. The reaction that provide energy for the muscle will produce carbon dioxide as side product in cellular respiration.
