<span>Personal protective equipment is only helpful if regulations for using it are followed carefully. If it is not worn and used properly, then it will not function properly and it might not provide the protection that is needed in the situation. For example, a helmet is only effective if it is fitted properly and snugly on the head. Otherwise it could fall off in an accident and be rendered useless.</span>
Option C. the larger A pairs with the smaller T, and the larger G pairs with the smaller C.
D) laboratory experiments because every experiment needs a control and a variable.
Answer:
Increasing the alveolar ventilation rate will increase the partial pressure of oxygen in the alveoli.
Explanation:
Alveolar Ventilation rate is the rate of air flow in the alveoli of the lung during normal breathing. It is measured in milliliters of air per minute (mL/min). The alveolar ventilation rate is an important factor in determining the concentrations (partial pressures) of oxygen and carbon dioxide in the functioning alveoli.
A high rate of alveolar ventilation, would result in a rapid influx of oxygen-rich air and efflux carbon dioxide-filled air from the alveoli. This ultimately results in an increase in the concentration of oxygen and a decrease in the concentration of carbon dioxide within the alveoli.
Effects of alveolar ventilation on partial pressures of alveolar carbon dioxide and oxygen (PACO₂ and PAO₂)
If the alveolar ventilation rate is increased (and carbon dioxide production is unchanged), then the partial pressure of carbon dioxide in the alveoli, PACO₂ will decrease.
If the alveolar ventilation rate increases, then the partial pressure of oxygen in the alveoli, PAO₂ will increase.
Answer:
The amount of energy stored in a molecule of ATP compared to the amount stored in a molecule of glucose is <u>less</u>.
Explanation:
Both ATP and glucose are energy containing molecules. However, a molecule of glucose has about 90 times more energy than a molecule of ATP.
But, ATP is used by most cells as the quickest source of energy. This is because ATP can easily be broken down to generate energy and it transfers energy very effectively.
A molecule of ATP is made up of adenine and three phosphate groups. The bond between the second and third phosphate is broken down to generate energy.
