Answer:
Food supply
Explanation:
foods will become toxic and can lose their freshness and value, especially for foods that are of higher quality
Answer: B. strong natural selection.
Explanation:
Speciation is the process by which new species form from the existing parent species. It occurs when the population of the species become reproductively isolated. In sympatric speciation the organisms living in the same geographical area becomes reproductively isolated due to changes in the behavior, morphology and genetic make up.
Among the option given, strong natural selection is the correct option. This is because of the fact that natural selection brings changes in the living being in terms of adaptation. The organism having better phenotypic trait will survive and reproduce. The beneficial traits will pass on to next generation may lead to evolution of new species. The members of the new species may not be able to breed with parent species.
Answer:
Photosynthesis removes carbon into the atmosphere, and cellular respiration releases carbon back into the atmosphere
Explanation:
The pharynx would need to come first in order for C to be correct.
B is also incorrect. Air flows through the bronchioles, then the
alveoli, and finally into or out of the capillaries where gas exchange
can occur with cells.
A is the only option that correctly describes the path of air through the respiratory system in the correct sequence.
The complete flow of air would be:
Nose>pharynx>trachea>bronchi>bronchioles>alveoli>gas
exchange with cells and then back out.
Your rate of breathing is primarily regulated by the amount of oxygen in your blood.
