Explain why plants along the road often die after the road is sprayed with a salt solution to melt ice
vovangra [49]

Explanation:

The salt solution is meant to lower the ice melting point hence keep most of the water from turning into ice even at zero degrees temperatures. The salts are dissolved in the water to form a salty solution that percolates the ground and reach plant roots. Because the salty water is hypertonic (more concentrated) to the cell cytoplasm of the plant roots, water is drawn from the plant by osmosis. This is the reversal of normal plant root absorption of water from the soil. This causes the plant root to wither and subsequently the whole plant to die. Remember in osmosis, water moves from the less concentrated solution to the more concentrated solution through a semipermeable membrane.

Why is density a derived unit?
Triss [41]
Density is a derived unit because it's not reported as a pure unit. (A pure unit would be something like kilograms or meters.) In contrast, the units for density are kg/m3. Density is the ratio of mass to volume; mass has the unit 'kilograms' (kg) and the unit for volume is cubic meters (m3).

Density is an intensive property, which means the amount of the material is irrelevant. The density of a substance is constant.

Answer:

The answer is:

B. Worms consuming the blood from mammals.

Algae isn't causing any harm to the sloth, rather its providing it with camouflage to hide from predators. Both creatures benefits since the algae gets to eat any parasites and other things in the sloths fur, plus they get a free ride and home in the process. The sloth isn't harmed and is helped by the algae since it provides camouflage (mutualism).

Tree frogs aren't causing harm to the trees since they are only using them to hide from predators, the tree serves as protection for the frogs and aren't harmed in the process (commensalism).

Two fish protecting each other from predators aren't harming each other in any way, rather they are protecting each other from another animal that wants to eat them (mutualism).

The worms however are harming the mammals because they are consuming the mammals blood, this is parasitism since one animal is benefiting and the other is harmed.

Hope this helps! :)
