Answer:
Charles Darwin
Explanation:
In Galapagos Islands, Darwin observed that animals from different parts were clearly similar but had very different features (such as beak type in finches). He imagined that all of these finches belonged to the same original species but had adapted to better fit their environment in different islands.
i would say that the student is incorrect. temperature can flucuate but that doesnt indicate error
Answer: Carbon dioxide, decrease
Explanation:
Cellular respiration is a set of reactions by which organic compounds (sugars) are degraded by oxidation to inorganic substances. This process provides energy in the form of ATP and to achieve this, many reactions occur in which electrons are passed from one molecule to another, called redox reactions. In the case of aerobic respiration, the final electron acceptor is molecular oxygen, which is reduced to water. Oxygen, like any gas, crosses the plasma membrane and then the mitochondrial membrane, and in the mitochondrial matrix it binds electrons and protons, forming water. It is in this final oxidation and in previous processes that energy is obtained. The reactions that extract energy from sugars such as glucose are catabolic reactions since a large molecule is broken into smaller molecules. For example, <u>when glucose is broken down in the presence of oxygen, six molecules of carbon dioxide (CO2) and six molecules of water are obtained. Both CO2 and water are eliminated by lung exhalation.</u>
In the event that this carbon dioxide is not completely eliminated, something called respiratory acidosis occurs, which is one of the disorders of the acid-base balance due to a decrease in the frequency of respirations or hypoventilation. The increase in the concentration of carbon dioxide in the blood causes the pH value to decrease. This scale is a measure of the degree of acidity or alkalinity of a substance or solution. A pH value of less than 7 means it is more acidic, and a pH value of more than 7 means it is more alkaline. <u>Carbon dioxide is constantly produced as the body metabolizes energy, which will accumulate in the circulation rapidly if the lungs do not remove it properly</u>. Alveolar hypoventilation thus leads to an increase in arterial CO2 partial pressure. The increase in pressure in turn decreases the ratio of bicarbonate (HCO3) to bicarbonate pressure with a consequent increase in acidity or decrease in blood pH. The body's metabolism rapidly generates a large amount of carbonic acid (H2CO3) and non-volatile acid. The lungs normally excrete the volatile fraction through ventilation without accumulation of acid in the blood but in this case this is not possible and this accumulation of carbonic acid causes the pH to rise. This disrupts homeostasis, a form of equilibrium that is achieved through a network of feedback control systems that constitute the self-regulatory mechanisms.

This is the answer because this is the highest point of the parabola
Answer:Confederation means a group of nations united together, but are not of the same. State governments usually handle the rights and laws for each citizen within it's 'territory'. therefore, your answer should be:
