melisa1 [442]

Answer:

animals also include vitamins, which are organic compounds required in microgram or milligram amounts.[Since plants are the primary origin of nutrients for humans and animals, some micronutrients may be in low levels and deficiencies can occur when dietary intake is insufficient, as occurs in malnutrition, implying the need for initiatives to deter inadequate micronutrient supply in plant foods.

The picture represents gas exchange in the alveoli. Observe what is happening at location X.
aivan3 [116]

A

CO₂ is the waste product of respiration of cells. Oxygen, on the other hand, is required in cellular respiration. Therefore at the alveolar in the lungs of an organism, CO₂ will be expelled while O₂ will be taken in.

Explanation:

This occurs passively due to the diffusion gradient, CO₂ usually has a higher concentration in the blood and lower concentration in alveoli hence this gas diffuses from the bloodstream into the lungs. On the other hand, oxygen is higher in concentration in the alveoli than in the blood capillaries hence difuses into the blood and taken to the cell for respiration. The CO₂ in the lungs is then expelled through exhalation of the lungs.
