Answer:

Divide the number of boxes with a dominant allele by four and multiply the result by 100 to get the percent chance that an offspring will have the dominant trait. For example (2/4)*100 = 50, so there is a 50 percent chance of an offspring having brown eyes.

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

photosynthesis and cellular respiration both use electron transport chains. what is the source of electrons for photosynthesis a
goldfiish [28.3K]

Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.

What is the electron transport chain's source of energy?

The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.

In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.

Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.
