Answer:
True
Explanation:
Pulmonary circulation transports blood through the alveoli for gas exchange. In this circulation the blood that comes from the veins initially has low oxygenation, and then leaves the right ventricle of the heart through the pulmonary artery, enters the lungs and returns to the heart with arterial and oxygenated blood
The bronchial circulation is well oxygenated and provides oxygen to the lungs. The structures to which this oxygen contributes in lungs are those that do not participate in a gas exchange.
Answer:
Nitrogen-fixing bacteria are prokaryotic microorganisms that are capable of transforming nitrogen gas from the atmosphere into “fixed nitrogen” compounds, such as ammonia, that are usable by plants.
Explanation:
Answer:
Genes that are relatively close to one another on a chromosome will move with one another during the process of fertilization and meiosis. Thus, there will be a lined inheritance for these genes. On the other hand, genes that are found on different chromosomes will have independent inheritances because every pair of the homologous chromosomes will be positioned differently when the
y are arranged at the middle of the cell during the first meiotic division.

The answer is <span>b. transport proteins.

Facilitated diffusion is the process of passive transport, which means without using of energy, of ions and molecules across a cell membrane. Although, this process does not require energy such as active transport, transport proteins are required. The role of transport proteins in facilitated diffusion is to provide a hydrophilic route within hydrophobic lipids of the membrane, and that way facilitate ions and molecules to cross the membrane.
Answer:
production of new gene combination
Explanation:
cause it doesnt occur during meiosis
