Answer:

pressure within the alveoli of the lungs

Explanation:

Pulmonary ventilation involves three different pressures:

Atmospheric pressure

Intra Alveolar (intrapulmonary) pressure

Intrapleural pressure

Atmospheric pressure is the pressure of the air that is exerted outside the body. Intrapulmonary pressure is the pressure exerted inside the alveoli of the lungs. Intrapleural pressure is the pressure within the pleural body cavity.

A couple without an ancestral history of Tay-Sachs disease (a rare autosomal recessive) have two normal children and an infant a

Bas_tet [7]

Answer:

The probability is 25%.

Explanation:

Let the dominant allele for the disease be 'T' and recessive allele be 't'.

The couple with normal phenotype produces an infant with the Tay Sach's disease.
As the disease is autosomal recessive in nature, it will get expressed in a homozygous recessive condition, that is, when the genotype is : tt.
As the normal parents are producing a diseased offspring, the both parents must be heterozygous dominant (Tt) for the disease allele.
The brother of the husband and the sister of the wife, both having a normal phenotype, can have the following genotypes, TT or Tt.
If either of the individual (brother or sister) has TT genotype and the other has other has either TT or Tt genotype, there is zero probability that they will produce an offspring with the disease.

Which of the following is NOT a source of dissolved oxygen in the water?

lesantik [10]

Answer:

A. humans going underwater and exhaling

Explanation:

The dissolved oxygen in water refers to the amount of oxygen that is found in water. However, there are various ways that oxygen dissolves in a body of water, these includes;

- Photosynthesis of aquatic plants: Oxygen is the waste product of the photosynthetic process carried out by green plants. Hence, when aquatic plants undergo photosynthesis, oxygen from them tend to dissolve into water.

- Diffusion from the atmosphere: Oxygen from air or atmosphere also dissolves in water

- aeration as water moves over rocks and debris, and from wind and waves

However, humans do not exhale oxygen but carbon dioxide, hence, it is not a source of dissolved oxygen
