A researcher wants to determine if ponds and lakes downwind of a coal-burning power plant are affected by the plant’s emissions. The best parameter from the water in the ponds and lakes to measure in order to determine the effect of the plant’s emissions on the aquatic ecosystems is
<u>A) pH</u>
Explanation:
- PH stands for Potential of Hydrogen. It refers to the hydrogen ion concentration in a solution.
- The majority of aquatic creatures prefer a pH range of 6.5-9.0, though some can live in water with pH levels outside of this range. Aquatic pH levels. The optimum pH levels for fish are from 6.5 to 9.0. Outside of optimum ranges, organisms can become stressed or die.
- It is the measure of the acidity or alkalinity of a solution. The PH value ranges from 0 to 14 on a pH scale.
- pH can be measured by measuring the voltage produced between two special electrodes immersed in the liquid solution. One electrode, made of a special glass, is called the measurement electrode.
- PH is zero that means hydronium ion concentration is zero and pH is 14 that means hydronium ion concentration is 1.
- Acids and bases have various strengths, all depending on their pH . An extremely strong base would be more dangerous than a weak acid, and vice versa.
Answer:
The closer a planet is to the sun, the stronger the sun's gravitational pull on it, and the faster the planet moves.
Answer:
Interspecific competition occurs between individuals of different species. Intraspecific competition occurs between individuals of the same species.

The rain gauge is an instrument used by meteorologists to measure the amount of precipitation in a particular region in a particular amount of time.
The rain gauge is placed on the ground in order to collect the rain or the precipitation sample. The rain gauge is labelled with the quantities, which can be used to measure the amount of precipitation.
So, the correct answer is option (a). on or near the ground.
