QUESTIONS & ANSWERS 2026/2027
The integumentary system is composed of skin, hair, nails and glands. The skin contains areolar tissue.
Areolar tissue contains fibroblast and macrophage cells. What characteristic of life does this represent? -
ANS ✔✔Organization
A decrease in blood water levels is detected in the brain. The brain sends signals to the pituitary gland to
release hormones that communicate with the kidney to reabsorb water, which will increase blood water
levels. This represents what life property? - ANS ✔✔Homeostasis
What sequence increases in complexity for levels of biological organization? - ANS ✔✔atoms, molecule,
cells, tissues, organs, systems
Based on levels of organization, which example represents the broadest level? - ANS ✔✔Mississippi
River
Place the steps of the scientific method in order from beginning to end.
1) Form a hypothesis
2) Analyze the results
3) Perform the experiment
4) Form a conclusion
5) Make an observation
6) Support or reject the hypothesis - ANS ✔✔5,1,3,2,4,6
When a sperm uses chemical signals to navigate the swim towards the egg, it is positive response. This is
a form of - ANS ✔✔Response
Which discipline would one practice if studying the development of zygotes (fertilized eggs) in
mammals? - ANS ✔✔embryologist mammalogist
When the brain, spinal cord and nerves of the body communicate with each other, it represents the
_______________ level of organization. - ANS ✔✔System
An experiment tested the health effects of a nutritional supplement by the following procedure:
People were asked to choose to join the experimental group or the control group. People in the
experimental group were given the supplement added to a pink, strawberry-flavored drink. People in the
control group were given a glass of water. One hour later, the people were asked "Do you feel better?"
How would you improve the experimental protocol? (Select all necessary changes.) - ANS ✔✔*The
drinks should both look and taste the same.
*People should be randomly assigned to one group or the other.
*The assessment should measure something more specific, such as blood pressure.
Which is an example of a hypothesis that can explain the observation, flashlight does not work? - ANS
✔✔The batteries are dead.
