Susan, a mother with Type B blood, has a child with Type B blood. She claims that Craig, who has
laiz [17]

Answer:

A child with type B blood can have a mother with type B blood and a father with type O blood so the judge grants her request and decides due to Susan is right and Craig must pay child support (option b).

Explanation:

Susan is right in this case because her <u>son with type B blood may have a mother with type B blood and a father with type O blood</u>.

Blood types, according to the ABO system, depend on the existence of surface antigens A or B —Types A, B and AB— or their absence in the erythrocyte membrane.

In the inheritance of blood groups A and B are co-dominant, while the absence of antigens —type O— is a recessive trait.

Assuming that Susan has a genotype B/B and that Craig has a genotype O/O:

<em>Alleles      O     O </em>

<em>B            B/O  B/O </em>

<em>B            B/O  B/O</em>

So it is very likely that the child is Craig's son and Susan is right.

What is the only reasonable and ethical way to achieve zero population growth
dybincka [34]

Answer:

By not having more offspring.

Explanation:

There are many ways of reaching a zero population growth, but some of them are 0% ethical. But, if the population stops having offspring, there won't be a population growth, instead, the population will decrease in number.

  • In 2017 the country with the biggest population was China, and the country with the biggest population growth in that same year was South Sudan, with a 3,83% population growth, according to statista and IndexMundi
  • Currently, in 2019, China still is the country with the biggest population, and, as for the highest population growth this year, we will only be able to say with 100% certainty when the year ends.

Hope it helped,
