Homeostasis - Answer✔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?
organization - Answer✔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?
Mississippi River - Answer✔Based on levels of organization, which example represents the
broadest level?
5,1,3,2,4,6 - Answer✔5,1,3,2,4,6Place 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
the batteries are dead - Answer✔Which is an example of a hypothesis that can explain the
observation, flashlight does not work?
System - Answer✔When the brain, spinal cord and nerves of the body communicate with each
other, it represents the _______________ level of organization.
response - Answer✔When a sperm uses chemical signals to navigate the swim towards the egg,
it is positive response. This is a form of
embryologist mammalogist - Answer✔Which discipline would one practice if studying the
development of zygotes (fertilized eggs) in mammals?

*People should be randomly assigned to one group or the other.
*The drinks should both look and taste the same.
*The assessment should measure something more specific, such as blood pressure. -
Answer✔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.)
atoms, molecule, cells, tissues, organs, systems - Answer✔What sequence increases in
complexity for levels of biological organization?
* Carbonyl
* Hydroxyl - Answer✔What functional group allows sugars (CnH2nOn) to be water soluble?
Select all that apply.
basic to 7.4 - Answer✔Normal (homeostatic) pH level of blood serum's pH is around 7.4.
Carbonic acid is released in the blood to help maintain a pH when the blood has high hydroxyl
levels. This would cause pH to change from
The horizontal rows of the table, or periods, indicate chemical reactivity. For instance, the
bottom row represents the unreactive noble gases. - Answer✔In the early years, there were
actually multiple ways of graphically representing information about the elements. The
scientific community settled on the current one based on Mendeleev's 1869 periodic table,
because it is so useful.
Of the following statements about the periodic table, which one is INCORRECT?
reversible reaction - Answer✔The equation below represents a(n)____________________.
2NO2 ↔ N2O4
Breaking of hydrogen bonds requires a lot of energy - Answer✔Why does water boil at a higher
temperature than butter, which is non-polar?
Isotopes - Answer✔Carbon-12, Carbon-13, and Carbon-14 are examples of
baking soda - Answer✔Before the battery in the car is jumped, the individuals notice the hook-
ups on the battery are corroded by acid. What substance can be used to clean the acid?
