Answer:
Breathing rate is most likely to increase if the blood level of carbon dioxide increase.
Explanation:
Breathing rate is the number of breaths of a person during a specific time, is usually the number of respiratory cycles that occur per minute. External respiration is the process of exchanging oxygen and carbon dioxide from the outside of the human body to pulmonary capillary blood. Once in the lungs, oxygen (and carbon dioxide to a very small extent) through the alveoli, pass into the red blood cells of the pulmonary vein blood. Carbon dioxide reacts in the blood with water, thanks to an enzyme, giving rise to bicarbonate. Blood reaches the heart, and is pumped into the cells by systemic arteries. The oxygen in the blood crosses the cell membrane and in turn, an exchange occurs, since the cell expels carbon dioxide and oxygen that it has not used. Once the exchange is done, the blood is conducted through the systematic veins with oxygen whose partial pressure is lower, and with an increase in the partial pressure of carbon dioxide. It reaches the heart again, leads through the right atrium and ventricle and finally travels through the pulmonary artery to the lungs where the air is expelled (expiration). Breathing rate tends to increase when the level of carbon dioxide in the blood increase.
Answer:
Absorption is the process of absorbing nutrients in the form of molecules into the blood. Therefore, this is the key difference between digestion and absorption. Digestion starts in the mouth while absorption starts in the stomach. Moreover, digestion occurs from mouth to intestine while absorption mostly occurs from the stomach to intestine.
Explanation:
To make an argument about how environmental imbalance affects the ecosystem of the Chesapeake Bay, research on reliable sources on the topic is necessary.
<h3 /><h3>How is the Chesapeake Bay?</h3>
The bay corresponds to the largest ecosystem of estuaries in the USA, being a source of diverse types of habitat for wildlife, with more than 3,600 species of animals and plants.
An example of the environmental imbalance in the area is the commercial and recreational fishing of blue crab, whose population had a significant reduction in 2022.
Therefore, environmental factors and human exploration are responsible for generating such an imbalance, and the development of policies and actions to promote sustainability is essential.
