Answer:
Molecules in a liquid have enough energy to move around and pass each other. ... the thing you add to the water is pushed around by the water molecules. Since the molecules in warm water move around faster, the material spreads out quicker in the warm water than in the cold water.
Explanation:
Given that organisms accumulate contaminants into their bioavailable fractions, we can conclude that the most likely outcome of this pollutant on the oysters is that <u>heavy metals will </u><u>bioaccumulate </u><u>in the oysters.</u>
Heavy metals that are often found in water include:
- Lead
- Copper
- Arsenic
- Cadmium
- Manganese
and more.
Though some metals are water-soluble, this does little to lessen the negative impact of their presence in the water. Water is used as an essential resource for all life. Metals in high concentrations, even those soluble in water, have been shown to be <em>fatal </em>to many organisms, including oysters.
Though oysters would suffer to a degree from biomagnification, <u>which is the accumulation of toxins in an organism through the food chain,</u> this will most likely become a serious problem higher up on the food chain, as the oysters are consumed by predators.
The most likely outcome of these pollutants in the water is that the Heavy metals will bioaccumulate in the oysters. This is due to the fact that the oysters will absorb the metals from the water. At high enough concentrations, this will lead to a decrease in the number of oyster offspring, possibly even reducing it to half.
