Readme [11.4K]

Answer: The oxygen content of the water decreases

Explanation:

The sun shining on a tidal pool during a hot day heats the water, causing some water to evaporate. Because the water has become warmer and saltier, the oxygen content of the water decreases.

The temperature and the salt content of a body of water determines how much oxygen it can hold.

The oxygen content of warm water decreases because the temperature of the water causes the water molecules to move faster. This leads to the expulsion of oxygen from the water, making it contain less oxygen.

Also, salty water will lead to a decrease in oxygen because of the presence of sodium chloride ions.

Therefore, a warmer and saltier water will contain a less amount of oxygen.

Phantasy [73]

Answer:

unicellular - both prokaryotes and eukaryotes

contain mitochondrion - eukaryotes only

are generally less than 2 pm - Prokaryotes only

multicellular - eukaryotes only

lack membrane-bound organelles - prokaryotes only

Explanation:

Prokaryotes are generally unicellular, that is, they are made up of single cells only. However, there are unicellular and multicellular eukaryotes with some eukaryotes like humans and advanced plants having as many as millions of cells.

Prokaryotes generally lack nucleus and other membrane-bound organelles such as chloroplast and mitochondrion. Eukaryotes on the other hand have nucleus and membrane-bound organelles such as mitochondrion and chloroplast.

When it comes to size, prokaryotes are generally small and microscopic while eukaryotes consist of both microscopic and macroscopic cells or organisms. However, prokaryotes are generally smaller than microscopic eukaryotes.
