a) Purpose:
b) Hypothesis:
c) Prediction
d) Describe the basic procedure you would use:
e) How will you collect your data?f) What results would you expect to see from this experiment?
The number of uncamouflaged animals will be far less than that of the camouflaged animals at the end of the experiment.
What is an experiment?An experiment is a detailed study that tends to identify cause and effect relationship.
The hypothesis in this experiment is that camouflage helps animals to survive in their habitat. The predication is that animals that are camouflaged are able to escape predation owing to the camouflage.
The best test procedure is to observe animals that are camouflaged and those that are not camouflaged in the wild for a period of about three months. Observe whether the number of uncamouflaged animals decreased more than that of the camouflaged animals after three months.
At the end of the experiment, it is expected that the number of uncamouflaged animals will decrease far more than the number of camouflaged animals.
The data will be collected using an unmaned drone over the area of study.

How does your body normally gather information for your brain
to process?
Answer:
Using information gatherers on your body such as eyes, nose, mouth, tongue, ears, ect.
Explanation:
Answer:
The brain follows signals through the nervous system. The nervous system sends a signal of what we want to do seconds before it happens, to ensure quick reactions. For instance, when we touch a stove, our nervous system already sent the signal seconds ago in an attempt to prevent your skin cells from being burned off. That is why we immediately pull back from intense heat unless we tell ourselves "wait, no!" before the process is over.
