Which individuals would be expected to suffer from a deficiency of water-soluble nutrients?
almond37 [142]

Individuals who suffer from illness or infection may have poor absorption or increased excretion suffer from a deficiency of water-soluble nutrients

  • The B vitamins — folate, thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B6, and vitamin B12 — and vitamin C are the nine water-soluble vitamins.
  • A clinical condition caused by a deficiency in one or more of these water-soluble vitamins can have serious morbidity and death effects.
  • Water-soluble vitamins are quickly absorbed by the body, so you won't need to store a lot of them to help maintain your body's nutritional needs balanced naturally.
  • Serious deficiencies may result in Wernicke-Korsakoff syndrome and beriberi, two diseases.
  • Various symptoms, such as anorexia, weight loss, decreased neurological function, mental health issues, muscle weakness, and enlarged hearts, are linked to these illnesses.

A father has AB blood and his wife has type O blood. What are the possible blood type percentage of their children.​
Zolol [24]

Answer:

If a father has a blood type AB and his wife has a blood type O, their children could be a blood type A or B, with a 50/50 chance.

Explanation:

Blood type and heredity are determined by surface antigens on the red blood cell, called A and B. The surface antigens provided by each parent are genetically encoded:

  • <em>Blood type A </em><em>corresponds to the presence of antigen A, and its genotypic expression can be A/A or A/O. </em>
  • <em>Blood type B</em><em>, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen. </em>
  • <em>AB blood</em><em> —due to co-dominance— has a gene for A and another for B, with genotype A/B. </em>
  • <em>Blood type O</em><em>, characterized by the absence of surface antigens, behaves as a recessive trait, which only manifests itself in the absence of surface antigens A and B. The genotype is O/O. </em>

In the case posed the father has the blood type AB and the mother the blood type O, so:

- ♂ blood type AB, alleles A|B

- ♀ blood type O, alleles O|O

The crossing can be seen graphically in the diagram:

Alleles A B

O A|O B|O

O A|O B|O

According to this, the offspring of this man and his wife could be:

  • Children with blood type A, genotype A|O, 50%
  • Children with blood type B, genotype B|O, 50%
