The given statement is example of the bioaccumulation.

What is phytoplanktons?

Phytoplankton, a flora of freely floating, often minute organisms that drift with water currents.

Bioaccumulation is the accumulation of contaminants by species in concentrations that are orders of magnitude higher than in the surrounding environment.

Contuining contamination of chemical leads to bioaccumulation in phytoplanktons population.

The density of water is 1.00 gram/milliliter. What is the volume in milliliters of 1.00 mole of water? Express your answer to th
Kay [80]

Answer: 18.0152 milliliters

Explanation:

Hi, to answer this question we have to apply the next formula:

Water volume = water mass / water density

Since 1 mol of water weights 18.0152 grams

Replacing with the values and solving:

Water volume = 18.0152 g / 1 g /ml = 18.0152 milliliters

Feel free to ask for more if needed or if you did not understand something.

Which of the following is a definition of a base? O a. behaves as a catalyst. O b. accepts H ions from acids. Oc. turns cloudy w
yan [13]

Answer: b. accepts H^+ ions from acids

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydronium ions (H_3O^+) in water.

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates H^+ ions and a base is defined as a substance which accepts H^+ ions.

NH_3+H_2O\rightarrow NH_4^++OH^-

Here water is donating H^+ ions, and thus act as acid and ammoia NH_3 is accepting H^+ ions from water and thus is a base.

According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.

Thus base is a substance which accepts  H^+ ions from acids.
