Answer:
Decrease your PH
Explanation:
Acid rain causes the aquatic environment to have very low PH levels. In addition, the aluminum found in the soil escapes into lakes and streams; unfortunately, increased acidity and increased levels of aluminum can be deadly for wildlife, among them ephemera, rainbow trout, smallmouth bass, frogs, spotted salamanders, crabs are affected river, and other creatures that are part of the food web.
Answer: D: it has a large capacity to hold heat
Explanation:
The property of water is that it has a large capacity to hold heat. It should be noted that in order to increase the temperature of water to a certain degree, it requires a lot of energy thereby water helps to regulate the temperature.
Other properties of water are that it is an excellent solvent, it is polar, it has adhesive and also cohesive properties.

Answer:
To perform an experiment that involves extract blood from partner's finger and determining their blood type, the safety gear that should be used are gloves, to protect you from any infectious agents in the blood (option B).
Explanation:
The use of gloves -both for trained and untrained personnel- is one of the biosecurity measures implemented to avoid contact with biological products, and to prevent infections when they are contaminated.
However, although the gloves prevent direct contact with the blood, they do not prevent puncture with objects -such as needles- so the use of gloves should be accompanied by other biosafety measures to avoid accidents in the laboratory.
