The answer to this would be true.
Aquatic nitrate pollution can result in algal bloom that when the algae die and are decomposed by bacteria, leads to hypoxia and the death of fish.
<h3>What is algal bloom?</h3>
Algal bloom is a dense spread of algae on the surface of water.
Algal bloom is caused by a process of eutrophication, which is the release of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.
Therefore, it can be said that aquatic nitrate pollution can result in algal bloom that when the algae die and are decomposed by bacteria, leads to hypoxia and the death of fish.

Answer:
Describe how the students would use the apparatus to show that there were microorganisms present in the air in the laboratory. Remember to think carefully about experimental design and how to make the results reliable.
Title: using apparatus to know the presence of microorganisms
aims and objectives: description of presence of microorganisms in the air
materials and method: petri dish, agar, distilled water, hand gloves, nose mask, pipette e.t.c
methodology: pipette is used to measure the amount of water in a petri dish and placed outside where hands can not be touched for 24 hours, after then the water is taken to the lab and agar is added for bacteria growth, after 24 hours, if the microbial growth is seen on the cultured plate, then it shows that the air is contaminated with microorganism which mixes with water when exposed to air
precaution: i ensured personal protective equipment are worn throughout the experiment.
conclusion: it is ascertained that air is contaminated with microorganism as a result of the above performed experiment
Explanation:
Answer: Regulation of activity by higher brain centers.
Explanation: The autonomic nervous system is part of the peripheral nervous system and is responsible for involuntary actions that occur without control, such as breathing and heart rate.
The somatic nervous system is also part of the peripheral nervous system but is responsible for the transmission of signals to the skeletal muscles and from receptors of external stimuli.
The peripheral nervous system regulates systems such as the nerves and ganglia that are found outside of the brain and spinal cord. Thus the autonomic and somatic nervous systems differ, but both are not involved in the regulation of activity by higher brain centers.
