The paper clip, which is denser than water, floats on the surface because of water's surface tension. Surface tension is a property of water that is the result of polar water molecules sticking together or water's property ofA)
adhesion.
B)
cohesion.
C)
buoyancy.
D)
capillary action.

Answers

The answer is cohesion. The high surface tension helps the paper clip (with much higher density) float on water. The property of a liquid that allows it to resist an external force, due to cohesive nature of its molecules. Cohesion refers to the attraction of molecules for molecules of the same kind. Water molecules have strong cohesive forces due to their ability to form hydrogen bond with each other.

Answer:

The answer is cohesion.

Which statement illustrates how human activities can most directly change the dynamic equilibrium of an ecosystem?Water pollution causes a decrease in fish populations in a river.
A hurricane causes a stream to overflow its banks.
Increased wind increases water evaporation from a plant.

Answers

The best answer would be the first statement. The first sentence which is 'water pollution causes a decrease in fish populations in a river.' illustrates how human activities can most directly change the dynamic equilibrium of an ecosystem.

Answer: Water pollution causes a decrease in fish populations in a river.

Explanation:

An ecosystem is a biotic community which includes abiotic (non-living) and biotic (living) components. The abiotic components includes water, sunlight, wind, soil and temperature whereas the biotic components includes the living beings such as plants, animals, microbes and other. The dynamic equilibrium of the ecosystem can be defined as the condition in which the abiotic factors of the ecosystem supports the life of the biotic factors without undergoing any drastic change which could negatively affect the population of living beings.

The river water is an abiotic factor which can be a habitat of large diversity of marine flora and fauna. The pollution of water could negative affect the population of the fish residing in the river. This will disturb the balance of ecosystem. As, in the ecosystem various species interact with one another to survive. Hence, the dynamic equilibrium will be changed.
