Answer:
Explanation:
Water tends to move in nature. This movement is facilitated by an osmotic gradient created as a result of OSMOSIS. Osmosis is the movement of water from a region of low solute concentration (high solvent concentration) to a region of high solute concentration (low solute concentration) through a semi-permeable membrane.
Salt contributes to the tonicity of the soil it was sprinkled in the sense that it makes the solute concentration of the soil higher (hypertonic) than that of the plant cell (hypotonic). This creates an osmotic gradient causing the movement of water from the plant cell into the road containing salt in order to form an osmotic balance. The water passes through the cell membrane of the plant cell which acts as the semi-permeable membrane in this case.
The movement of water out of the cell will eventually make the plant cells around that road area shrink (reduce) and likely die, due to loss of water content.
Answer:
Pulmonary circulation refers to the circulation of blood in which deoxygenated blood is pumped from the heart to the lungs and oxygenated blood is returned to back to the heart. Pulmonary circulation only occurs between the heart and the lungs.
Systemic circulation refers to the circulation of blood in which oxygenated blood is pumped from the heart to the body and deoxygenated blood is returned back to the heart. Systemic circulation occurs between the heart and the entire body

Answer:
May be of the environment they live or genetics.
Explanation:
This naked mole rat species evolved back to an ectothermic life style rather than staying endothermic like all other mammals because of the environment they live or change in the genetic makeup. The main reason for this evolution may be the environmental they lives or through the change in genetic makeup of this naked mole rat species so both factors can contribute in the evolution.
Answer:
D
Explanation:
The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down their concentration gradient, by simple diffusion.
Answer: Oxygen
Explanation: Oxygen is the gaseous by product of photosynthesis.
Carbon dioxide + water + energy from light produces glucose and oxygen.
Sunlight energy.
6CO2 + 6H2O ------> C6H12O6 + 6O2
the excess oxygen they produced during photosynthesis is contributed directly to the oxygenation of the Earth.
