Answer:

Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body. Although gas exchange is a continuous process, the oxygen and carbon dioxide are transported by different mechanisms.

Transport of Oxygen in the Blood

Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues.

Hemoglobin

Hemoglobin, or Hb, is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits (Figure 20.19). Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red. As a result, oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red.

Classify the mutations as somatic or inherited
Sergio [31]

Answer:

Somatic mutations : option (A) and option (D).

Inherited mutations : option (B) and option (C).

Explanation:

Mutations are permanent changes in the genetic material due to alterations in DNA sequence. Mutations may be somatic or inherited (or germline).

Somatic mutations are those mutations that arise in somatic or normal body cells and cannot transfer from parents to their offspring. As skins cells and lung cells are somatic cells, option (A) and (D) represent somatic mutations.

Inherited mutations are those mutations that arise in sex cells (gamete forming cell) and transfer from parents to their offspring due to transfer as these cells form mutated gametes. As egg cells and sperms cells are sex cells, option (B) and (C) represent inherited mutations.

The synthesis of nucleotides requires several amino acids. Sort each amino acid as a precursor in the synthesis of purines, pyri
Lapatulllka [165]

Answer:

Glycine is required for purines, aspartate for pyrimidines, glycine and aspartate for both purines and pyrimidines. The remaining amino acids are not required for the synthesis.

Explanation:

Nucleotides are the monomer for the synthesis of DNA and RNA. The two main class of nitrogenous bases are purines and pyrimidines. These nitrogenous bases require the amino acids as a precursor for their synthesis.

Glycine is the simplest amino acid and required for the synthesis of purines. Aspartate is required for the synthesis of pyrimidines. Glutamine and aspartate are required for the synthesis of both purines and pyrimidines. Lysine, leucine, alanine, histidine, methionine, tryptophan and alanine are not used as a precursor for the nucleotides.
