Answer:
It increases genetic variation.
Explanation:
Meiosis does not decrease the number of chromosomes nor increase the number of them, it merely splits them.
While it could increase mutations, this might not necesarily be a good thing.
However, it does increase genetic variation, especially during the process where crossing over occurs. Increased genetic variation is beneficial for the population for many reasons like higher resistance to certain diseases. Increasing genetic variation also makes a species look unique from other members of the species.

scientists often test their hypotheses with controlled experiments. which of these is a rule for conducting a controlled experiment?
a. change at least two variables at a time
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only one variable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.

Answer:
(b) increased travel of individuals from endemic regions to the United States,
The possible reason that lead to the reemergence of malaria in the United States is increased travel of individuals from endemic regions to the United States. The correct option is b.
What is malaria?Malaria is a potentially fatal disease caused by a parasite that infects a specific type of mosquito that feeds on humans. Malaria typically causes severe illness, including high fevers, shaking chills, and flu-like symptoms.
Malaria is typically transmitted through the bite of an infective female Anopheles mosquito. Only Anopheles mosquitos can transmit malaria, and they must have previously been infected through a blood meal taken from an infected person.
It has been determined that mosquitoes become infectious more quickly, resulting in increased malaria transmission and increased travel from endemic regions to the United States.
Thus, the correct option is b.
