If a vulture which is a scavenger, consumes remains of a racoon on the side of a highway, it will help to control environmental pollution and stop the spread of diseases by the dead animal.
<h3>What are scavengers?</h3>
Scavengers are organisms which feed on leftover or carcasses of dead organism. Example of a scavenger is the vulture.
Vultures feed on dead organisms or food that has been left over by other organisms.
Scavenging plays an important role by removing substances which may lead to spread of diseases from the environment.
Thus, if a vulture consumes remains of a racoon on the side of a highway, it will help to remove the carcasses which may serve as a breeding ground for diseases. It also helps to control environmental pollution.
In conclusion, scavengers like vultures help to control environmental pollution.

Oxygen-poor blood enters the heart through the right atrium. From there blood flows through the tricuspid valve into the right ventricle. When the heart contracts during the diastolic phase, this blood is pumped out through the pulmonary arteries that run toward the lungs. At the lungs, the blood is circulated through a series of progressively smaller arterioles until it flows through capillaries lining the lungs' alveolar sacs. It is here that gas exchange takes place as oxygen is taken up by the blood, and carbon dioxide is released into the waste air.After oxygenation, the fresh blood is circulated back through the bronchial veins and into the pulmonary veins. These run from the lungs and drain into the heart's left atrium. During the systolic phase of the heartbeat, the mitral valve under the left atrium opens and permits blood to pass into the left ventricle. This chamber is heavily muscled and it has the power to pump the oxygen-rich blood out through the aorta and into the rest of the body.
Answer:
D. on the surface, directly above the focus
Answer:
The given statement is True.
Explanation:
Scala media has endolymph as its constituent and endolymph is rich in Potassium ions (K+)
whereas
Scala tympani and scala vestibuli has in its composition Perilymph and Perilymph has sodium ions as their major constituent ions.
Therefore, scala media is Potassium ion rich while scala tympani and vestibuli are sodium ion rich.
