Complete Question: Julio wants to study the effect of water temperature on the hatching of fish eggs in a lake. which of these experimental designs would be most practical for julio?
a. he should put fish eggs in aquariums of lake water kept at different temperatures and observe.
b. he should build a computer model of fish eggs in a lake that has many different water temperature settings.
c. he should use cameras to observe fish hatching in the lake and temperature probes to monitor water temperature.
d. he should take water samples from lakes of different temperatures and observe for eggs and newly hatched fish.
Answer: is <em>a). he should put fish eggs in aquariums of lake water kept at different temperatures and observe. </em>
Explanation:
By viewing all four options the most accurate and near to possible is <em>option A. </em>Other three techniques are not doable and have higher chances of inaccuracy. The results fetch from other techniques will contain various error which results in wrong findings. Instead of studying and controlling whole lake water temperature, a sample of water lake should be taken and adjusted it's temperature accordingly under observation in a controlled and monitored environment. By doing so, the eggs can be monitored and observed under an adjusted temperature with full accuracy. Hence option A is more suitable and more realistic approach in finding the desired results.

Answer:
The answer is Brain Stem.
Explanation:
The brain part that we are least consciously aware of is the brain stem and the reason is because of how it operates and it's functions.
The brain stem is the part of the brain that is located at the end and controls the message flow between our body and our brain. It also regulates our physiological processes such as heart rate, blood pressure, breathing etc. without our notice.
I hope this answer helps.

Answer:
<em>The correct option is C) How does sunlight affect a model of a biogeochemical cycle?</em>
Explanation:
A scientific question can be described as a question based on which a hypothesis can be made and observations and experiments can be performed. The results from these experiments and observations would account for the validation of a hypothesis. Hence, a scientific question should be a question based on which a hypothesis can be made and experiments can be performed.
In the option C, the sunlight might increase or decrease various processes of the biogeochemical cycle. We can hypothesize and perform experiments to get the results. Hence, it is a scientific question.
