Which example below is an
example of conforming to the
environment?
1. The embryonic development of frog embryos
(tadpoles) slows at lower temperatures.
2. When blood sugar levels drop in humans,
glycogen is hydrolyzed to glucose and released
to the bloodstream.
3. The kidney of salt water fish (like tuna)
constantly excretes salts.

homeotherm and an ectotherm.
homeotherm and an endotherm.
heterotherm and ectotherm.
heterotherm and endotherm.
If we are not properly dressed on a cold winter day
our bodies react. We may experience less blood flow
to our hands and feet. In this scenario, which type
of heat exchange are we influencing?
1. We are decreasing the amount of heat lost (convection)
to the surrounding air through our hands and feet to
maintain core body temperature.
2. We are increasing the amount of heat lost (radiation)
through our hands and feet to maintain core body
temperature.
3. We are releasing heat through evaporation to cool our
hands and feet.
4. We are decreasing the amount of heat (conduction) with
the surrounding air through our hands and feet to
maintain core body temperature.
What mechanism below is used to
remove water from the kidney?
1. Active transport of Na+ ions and water.
2. Active transport of Na+ ions, which allows
passive transport of water.
3. Passive transport of Na+ ions, which allows
active transport of water.
4. Passive transport of both Na+ ions and water.
Which example below is NOT likely an
example of an injury to your connective
tissue?

muscle tear
back injury
tendonitis
broken arm
knee injury

What type of epithelium below helps
with temperature regulation in
humans?
1. skin
2. mucus glands
3. digestive tract
lining
4. blood
5. sweat glands
6. 4 and 5
Think hard about movement of the blood through
blood vessels. There is a pulse associated with blood
flow. Blood flow is aided by body movement. Lastly,
blood pressure can be controlled unconsciously by
increasing or decreasing the diameter of the blood
vessel. Therefore, what type of muscle or muscles
are used to regulate blood flow in your body?
1.
2.
3.
4.
5.
cardiac muscle
skeletal muscle
smooth muscle

It is hard to separate the activities of the central and
peripheral nervous systems. Your eye detecting the image of
an apple (seeing an apple) involves first _________ nervous
system. The image is then interpreted by your __________
nervous system. If you decide to reach for the apple, you
first use your _______ nervous system followed by the
__________ nervous system.

The organ systems of your body need to
work together; therefore, performing any
task will likely involve more than one organ
system. Which organ system would not be
involved in eating an apple?
