<span>The sympathetic nervous system prepares the body for intense physical activity and is often referred to as the fight-or-flight response. The parasympatheticnervous system has almost the exact opposite effect and relaxes the body and inhibits or slows many high energy functions.</span>

Explanation:
The answers to the questions required for the design experiment above are :
- If shark attack are related to the number of elephant seals in an area, then shark attack will increase as the number of elephant seal increases
- If shark attack are unrelated to number of elephant seal in an area, then shark attack is unaffected by increase or decrease in number of elephant seal.
- The Control Group : Beaches or areas where elephant seals aren't present or period of the year when there are no elephant seal at the beach.
- The Experimental group : Beaches where varibale portions of elephant seals are found (area with high, medium or low).
- The Dependent variable : Number of shark attacks
- The Independent variable : The different number of elephant seals found.
- Data to be collected include : The number and type of elephant seals found at various beaches and the number of shark attacks recorded at the various points.
- John will be able to deduce if the number of elephant seals and number of shark attacks recorded corded are related.
The hypothesis of an experiment is a proposition which requires experimental testing in other to establish it's validity.
The Control Group refers to a portion of the subject which aren't given or exposed to the treatment used in an experiment.
The Experimental group are the portion of the subjects which are subjected to the treatment condition.
The Dependent variable is the measured variable is changes as the independent variables are tweaked.
Independent variable is the predictor variable, it causes a change in the output of the dependent variable.

Answer:
Women who carry one copy of the mutated gene still have normal color vision because they have another copy, which is not mutated, in the other X chromosome that will be the dominant one. As a result, the women are carriers of the mutated gene but not color blind.
Explanation:
Colorblindness is a sex-linked mutation. A woman has two X chromosomes, while a man has one X chromosome and one Y chromosome. The mutated gene that causes color blindness is on the X chromosome, and it is OPN1LW. So if a woman has one mutated OPN1LW in one of her two X chromosomes, the OPN1LW gene in the other X chromosome will be the dominant one stopping the woman from being colorblind.
In the case of men, as they only have one X chromosome, if there is a mutation on the OPN1LW in the X chromosome, the men will be colorblind because there is no extra copy of the gene, as it is in women.
I believe its true
hope this helped
