Answer:
D: Simple Diffusion
Explanation:
Diffusion is a transport driven by a concentration gradient. Gas molecules move from a place of high concentration to an area of low concentration. Knowing when blood is low in concentration and high in carbon dioxide it goes under gas exchange with air into the lungs.
Hope this helped! :)
I would go with c because its tells you right in there that the ecosystem help who lives around that area.
The statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.
<h3>What is eutrophication?</h3>
Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.
Eutrophication is one major effect of the anthropogenic activities that release inorganic nutrients such as phosphate, nitrate etc into aquatic ecosystems.
However, eutrophication has its negative impacts on biogeochemical cycle as it alters the cycling of these nutrients.
Therefore, the statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.

Answer:
A rise in blood carbon dioxide concentration.
Explanation:
The feedback regulation may be defined as the process in which the end product of the metabolic pathway regulates the homeostasis of the body. Two main types of feedback are positive feedback and negative feedback.
The negative feedback mechanism occurs when the end product of the reaction is responsible for the shutdown of the metabolic pathway and decreases its concentration. The breathing is controlled by the negative feedback mechanisms, the increase in carbon dioxide concentration acts as the negative sensor as this sensor is mainly responsible for the increase in amount of oxygen level and maintain homeostasis of the body.
Thus, the correct answer is option (c).
