Answer:
Dispersants
Dispersants are generally detergents or surfactants that help dissolve the oil stain in smaller drops. They remove oil from the water surface, making it enter and into the water column, increasing the speed of biological degradation. These dispersants, by removing oil from the water surface, protect birds, marine mammals, turtles and sensitive coasts. Chemical dispersants do not sink oil leaving it suspended in the water column. Dispersants should be avoided in shallow coastal waters, mangroves, swamps, or waters over coral reefs and algae due to their possible toxicity.

Explanation:
The blow-by gases that escape past the piston rings and get into the crankcase are mostly unburned fuel-air mixture.
The fuel is largely a mixture of hydrocarbons (HCs)
.
The PCV system captures these gases and feeds them back to the cylinder for further combustion.
A. is wrong. Carbon dioxide exits through the exhaust.
C. is wrong. Most of the oxygen in the incoming air is used for combustion in the cylinders.
D is wrong. The NOx gases exit via the exhaust and are trapped by the catalytic converter.
D is the answer..............................
The unethical part about the mice's treatment is that John's classmates are taping on the glass and teasing the mice.
<span>The answer is a. it causes plants and algae to grow quickly, suffocating organisms in the water. The rapid growth of organisms due to fertilizer runoff leads to a process called eutrophication. When the vegetation dies, the process of decomposition leads to the formation of excessive amounts of carbon dioxide, which in turn suffocates aquatic animals.</span>
