Answer:
External respiration: CO2 diffuses into the blood
Explanation:
External respiration is also called the pulmonary gas exchange. It refers to the diffusion of O2 from the air in the alveoli of the lungs to blood in pulmonary capillaries and diffusion of CO2 in the opposite direction from the capillary blood into the alveolar air. External respiration in the lungs is responsible for oxygenation of deoxygenated blood coming from the right side of the heart. The oxygenated blood is then returned to the left side of the heart.
Organic compound is generally any chemical compound that contains carbon. Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. Study of the properties and synthesis of organic compounds is the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonates and cyanides), along with a handful of other exceptions (e.g., carbon dioxide), are not classified as organic compounds and are considered inorganic. No consensus exists among chemists on precisely which carbon-containing compounds are excluded, making the definition of an organic compound elusive.[1]Although organic compounds only make up a small percentage of the Earth's crust, they are of central importance because all known life is based on organic compounds. Most synthetically produced organic compounds are ultimately derived from petrochemicalsconsisting mainly of hydrocarbons.
Answer:
The correct answer is option d) "orbitofrontal cortex".
Explanation:
The orbitofrontal cortex (OFC) is the region of the brain responsible of the cognitive process of decision-making. The OFC is involved in the senses of award and remorse based on the results of decision making actions. In this case Jerome exhibits impulsive behavior that lead him to break a man's nose for no reason and had no remorse for doing so. It is likely that Jerome has a tumor in the OFC, which affects his decision making judgement and his feeling of right and wrong.
Answer:
C) specialists.
Explanation:
The finches of the Galapagos Islands would be considered specialists. This is because the finches have diversified in a way in which each species has uniquely evolved to perform a very specific task (eating a particular type of food). Moreover, this process is known as adaptive radiation, as a single lineage (the original finch) undergoes speciation events that eventually fill divergent ecological niches, creating many related species.
Explanation:
The equation that shows the equilibrium reaction of carbon dioxide in the blood is the following one:
<h3>
CO₂ + H₂O ↔ H₂CO₃ ↔ H⁺ + HCO₃⁻</h3><h3 />
This equation describes the bicarbonate buffer system which regulates the pH of the blood.
- During hypoventilation, the CO₂ produced by the cells through metabolism is not released fast enough, so CO₂ levels in the blood increase. In this situation, the equation shifts towards the right, and an excess of protons is produced, therefore decreasing the pH and causing acidosis.
- During hyperventilation the breathing is very rapid and CO₂ is exhaled from the body at a very fast rate. In this situation, the CO₂ levels in the blood decrease, the equation shifts towads the left and the concentration of H+ thus decreases, causing alkalosis.
