Answer:
A sharp, ringing sound made by the collision of sonorous (especially metallic) bodies.
Answer:
C. Diffusion and no energy needed.
Explanation:
A - Passive transport doesn't require energy.
B - Osmosis would be if the 25% H2O went into the 82%
D - Active transport doesn't apply because molecules aren't moving across into a higher concentration.
Diffusion is when parts of the 82% go into the 25%.
Answer:
The correct answer is option E.
Explanation:
Voluntary hyperventilation results in alkalosis, not in acidosis. Alkalosis takes place when the body possesses too many bases. It can take place due to decreased levels of carbon dioxide or due to enhanced level of bicarbonates in the blood, that is, a base.
Emphysema directly impairs exhalation more than it directly impairs inhalation. Emphysema refers to a lung disorder, which leads to shortness of breath. In the individuals suffering from the condition, the air sacs in the lungs, that is, alveoli get damaged.
The hemoglobin-oxygen dissociation curve shifts to the right at the time of metabolic acidosis. The low partial pressure of oxygen within the lungs results in the constriction of pulmonary arterioles. Thus, all the mentioned statements are false.
Answer:
C. Natural selection is the process by which organisms with more beneficial traits are more likely to survive and reproduce.
Explanation:
Natural selection is an evolutional process by which species of living organisms with stronger or more beneficial traits have higher chances of survival and reproduction. In other words, it is the process by which organisms adapt and survive.
Organisms in a population are all different in their own ways. And those with characteristics or traits better suited for the environment are more likely to survive than those without. The selection prefers more beneficial traits and not wholly on the superiority of the organism. So, the survival and reproduction chance of an organism depends on the presence of traits beneficial to the environment, which is how nature selects. And in this process, those selected will dominate the population while those rejected will be reduced or even die.
Thus, the correct answer is option C.
