Answer:
The salt in the oceans comes from weathering and the erosion of the earth's crust.
Explanation:
The weathering can be described as the breaking down of rocks.
During the weathering of rocks, minerals will be dissolved from the land and salt is one of them. These minerals (salt included) will then be delivered into the oceans by erosion of the Earth's crust.
Erosion can be aided by wind, ice or water. Erosion removed weathered materials. When these weathered materials are removed, new materials (rocks) will be exposed to weathering thereby promoting continuous weathering processes
Answer:
Scientists discovered mechanisms that protect tapeworms from being digested by their host. ... They also needed a mechanism to protect themselves from intestinal substances, specifically from digestive enzymes. One of such enzymes called trypsin breaks down proteins.
Explanation:
For example:Parasites can hide away from the immune system by invading immune-privileged tissue such as the central nervous system or the eye (Bhopale 2003). Also some parasitoids place their eggs inside tissue such as the fat body that is not well patrolled by the host's immune system
Answer: the increased surface area aids in the better absorption of drugs.
Explanation: According to Noyes- Whitney equation, increased absorption of drugs depends on the rate of dissolution which is modified by altering the surface area. Reduction of the drug size from solid to powder form increases the specific surface area and the dissolution rate. This unique quantity makes it a fast acting medication since it's absorbed faster.
