Answer:

If the mother's blood type is O, and the child's blood type is B, a man would be exonerated from paternity if he has blood type A or O.

Explanation:

In the above case, if a mother has blood type O and her child has blood type B, a man can be exonerated from paternity only if his blood type is A or O, and responsible if he is type B or AB.

The blood type is defined by the presence of surface antigens in the red blood cell, called A and B. The presence of each antigen is determined by a gene present on the parental chromosomes.

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

By making a hypothetical crossing between mother and man, one can observe why he can be exonerated.

<u>Man with blood type O </u>

♂ O|O

♀ O|O

Alleles     O      O

O           O|O   O|O

O           O|O   O|O

The only possibility, in this case, is to have children with type O blood. No chance of children B.

<u>Male with blood type A </u>

♂ A|O

♀ O|O

Alleles     A        O

O            A|O    O|O

O            A|O    O|O

In this case there is a 50% chance that the children will be blood type A and 50% chance that they will be O. No chance of children B.

In the case of a man A|A the result is 100% probability of children A|O, and no probability of children B.

<em>So, a </em><em>man with blood types A (any genotype) and O, can be exonerated from paternity</em><em>, since it is </em><em>impossible for him to have a child of blood type B, when the mother is of blood type O</em>.

ozzi
Having a skin that is pale, cold, and clammy are symptoms of heat exhaustion. Also, when your pulse is rapid, breathing is shallow are symptoms of such. One main cause of this would be being exposed to high temperatures especially when humidity is high and one is doing a physical activity. When no proper treatment, it could lead to heatstroke which may eventually cause death of the person. When one suspects that he is experiencing this, he should stop all that he is doing and rest. Then, he should move to place which has a cooler temperature. And drink fluids that are cold specifically water and sport drinks.

The process by which cells are drawn or attracted to an area by a microbe invader is known as ________.
Alexxx [7]

Answer:

chemotaxis

Explanation:

Chemotaxis is movement of the organism in the response to the chemical stimulus.

Bacteria, somatic cells and single-cell as well as multicellular organisms direct  movements of their body according to some chemicals in the environment. This is very important for the bacteria to find the food by swimming toward highest concentration of the food molecules or also to flee from the poisons.

<u>Thus, it is a process by which various cells are drawn to the target area by a microbe invader.</u>
