1 answer:

7 0

Plants absorb carbon dioxide,water and sunlight to make their own food,grow and release oxygen through photosynthesis. They're a huge part in keeping our air clean. The carbon becomes part of the plant. ... When humans burn fossil fuels, most carbon enters the atmosphere as carbon dioxide.

Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. ... Carbon moves from the atmosphere to the oceans.

If the pregnant mother gets dizzy and has a drop in blood pressure when she is in a supine position, the condition is called?

Elena L [17]

Supine hypotension syndrome is the medical term for when a pregnant woman feels lightheaded and has a dip in blood pressure while lying down.

Supine hypotension in pregnancy: what is it?

When you're pregnant, resting flat on your back might make some symptoms, including indigestion and shortness of breath, worse. Her blood pressure may also drop as a result of it.
Supine hypotension syndrome is the medical term for when her blood pressure drops while she is pregnant and laying on her back. When a pregnant woman lies supine, the gravid uterus pushes on the inferior vena cava, resulting in a reduction in central venous return. This condition is known as a supine hypotensive syndrome (also known as inferior vena cava compression syndrome).

The blood Group of Mother is O. The Blood Group of the Child is B. Man Exonerated If He to Blood Group?

aalyn [17]

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.

Blood type A corresponds to the presence of gene A, and its genotypic expression can be A/A or A/O.
Type B blood, whose genotype is B/B or B/O, is due to the presence of a gene containing the B antigen.
AB blood —due to codominance— has one gene for A and another for B, with genotype A/B.
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.

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

Man with blood type O

♂ O|O

♀ O|O

Alleles 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.

Male with blood type A

♂ A|O

♀ O|O

Alleles A 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.

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