BIO 1050 EXAM 1 ECU ACTUAL TEST
QUESTIONS AND CORRECT ANSWERS
◉ True or False
All eukaryotes are multicellular.
Answer: False
◉ Our livers are responsible for processing particular drugs we take.
Therefore we would expect the liver to have lots of _______ .
Increasing the amount of this particular cell organelle is what
sometimes causes people to build up a tolerance to drugs, requiring
them to take ever increasing quantities of the drug to feel the same
effect.
Answer: Smooth endoplasmic reticulum
◉ Sperm are able to move largely due to their _____.
Answer: Cytoskeleton
◉ During endocytosis, particles are transported ____ the cell within a
_____ .
Answer: into, vesicle
, ◉ A hypothetical study examined the possible link between
thimerosal (a preservative in some MMR vaccines) and an increased
risk of developing autism. This study had a group of 1000 children.
Half (500) of the children were randomly selected to receive a MMR
vaccine that included thimerosal and the other half (500) of the
children were randomly selected to receive a MMR vaccine that did
not include the preservative thimerosal. All 1000 children were
monitored until the age of 6 and investigators recorded the number
of children who developed autism. What is the independent variable
in this experiment?
Answer: The presence/absence of thimerosal in the MMR Vaccine
◉ Plant parts that contain a lot of poisonous materials to protect
them from being eaten by animals would have many _____ .
Answer: Vacuoles
◉ Rough Endoplasmic Reticulum
Answer: folds and packages proteins for shipping
◉ Smooth Endoplasmic Reticulum
Answer: Makes Lipids, like hormones, and breaks down drugs and

◉ Golgi Apparatus
