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.

Answer:
1) A mutation appeared in one weed plant that made that weed not susceptible to the herbicide ( B )
2) The weed will survive long enough to reproduce ( B )
Explanation:
1) The most likely reason the weed remained is : A mutation appeared in one weed plant that made that weed not susceptible to the herbicide
The weed plant must have undergone some mutation in order to be resistant to the herbicide which would kill the weed before now
2) The most likely thing that will happen if the weed stays in place in that farm is : The weed will survive long enough to reproduce
The trait or mutation of the weed cannot just spread to other weeds nearby it can only spread by reproducing more weeds of same mutation
