What type of bond attracts one water molecule to
|\ |\ |\ |\ |\ |\ |\ |\ |\
another? - CORRECT ANSWERS ✔✔A Hydrogen Bond |\ |\ |\ |\ |\ |\
When a woman is giving birth, the head of the baby
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
pushes against her cervix and stimulates the release of
|\ |\ |\ |\ |\ |\ |\ |\ |\
the hormone oxytocin. Oxytocin travels in the blood and
|\ |\ |\ |\ |\ |\ |\ |\ |\
stimulates the uterus to contract. Labor contractions |\ |\ |\ |\ |\ |\ |\
become more and more intense until the baby is
|\ |\ |\ |\ |\ |\ |\ |\ |\
expelled. This is an example of __________. - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Positive Feedback |\ |\
Which of the following gives a cell structural support,
|\ |\ |\ |\ |\ |\ |\ |\ |\
determines the shape of a cell, and directs the movement |\ |\ |\ |\ |\ |\ |\ |\ |\
of substances through a cell? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\
✔✔The Cytoskeleton |\
__________ differ from one another in their number of |\ |\ |\ |\ |\ |\ |\ |\ |\
neutrons and atomic mass - CORRECT ANSWERS |\ |\ |\ |\ |\ |\ |\
✔✔Isotopes
The sternum (breastbone) is __________ to the vertebral
|\ |\ |\ |\ |\ |\ |\ |\
column. - CORRECT ANSWERS ✔✔Anterior |\ |\ |\ |\
, Three common components of a feedback loop are
|\ |\ |\ |\ |\ |\ |\ |\
_________, __________, and __________. - CORRECT |\ |\ |\ |\ |\ |\
ANSWERS ✔✔receptor, integrating (control) center, |\ |\ |\ |\ |\
effector
Which of these is an example of active transport? -
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
CORRECT ANSWERS ✔✔Transport of Na+ from a place of |\ |\ |\ |\ |\ |\ |\ |\ |\
low concentration to a place of higher concentration
|\ |\ |\ |\ |\ |\ |\
A red blood cell is placed in a hypertonic solution. This
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
means the concentration of solutes in the solution is
|\ |\ |\ |\ |\ |\ |\ |\ |\
__________ than the concentration of solutes in the |\ |\ |\ |\ |\ |\ |\ |\
intracellular fluid, and will cause the cell to ______________. |\ |\ |\ |\ |\ |\ |\ |\
- CORRECT ANSWERS ✔✔higher, shrink
|\ |\ |\ |\ |\
Chemicals in a solution can move down a concentration |\ |\ |\ |\ |\ |\ |\ |\ |\
gradient. This means the chemical will move from the|\ |\ |\ |\ |\ |\ |\ |\ |\
area of __________ concentration to the area of _________
|\ |\ |\ |\ |\ |\ |\ |\ |\
concentration. - CORRECT ANSWERS ✔✔high, low |\ |\ |\ |\ |\
During exercise, one generates excess heat and the body
|\ |\ |\ |\ |\ |\ |\ |\ |\
temperature rises. As a response, blood vessels dilate in |\ |\ |\ |\ |\ |\ |\ |\ |\
the skin, warm blood flows closer to the body surface, and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
heat is lost. This is an example of __________. - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔Negative Feedback |\ |\
