c. three: the renal artery and vein and the ureter
d. four: the renal artery and vein, the ureter, and urethra
e. five: the renal artery and vein, two ureters, and one urethra
3) which cell junction is unique to animals.
a. gap
b. tight
c. desmosomes
d. all are unique to animals
4) which statement about connective tissue is not true?
a. loose connective tissue contains fibroblasts, different types of fiber, and a nonliving
matrix.
b. fibrous connective tissue includes bone and cartilage.
c. blood is a connective tissue that contains a fluid matrix.
d. adipose tissue provides insulation and padding in organs such as the skin.
5) in the electron transport systems of chloroplasts and mitochondria,
a. the system consists of a series of membrane bound carriers that transfer electrons
from one carrier to another.
b. high energy electrons enter the system and low energy electrons exit the system.
c. energy release occurs when the electron transfers from one carrier to another.
d. all of the choices are correct.
6) what organisms are capable of photosynthesis?
a. plants only
b. plants and algae only
c. plants and some bacteria only
d. plants, algae, and some bacteria

10) the earth is actually farther from the sun during the period when the northern
hemisphere is having summer. how can this be explained?
a. the sun grows more powerful on a half-year cycle.
b. there is a six-month lag phase between sunlight being absorbed and lost.
c. the tilt of the earth presents the northern hemisphere in a more perpendicular angle,
and this increased sunlight more than offsets the decrease in sunlight due to the added
distance.
d. there must be some mistake in measuring the earth's orbit because if the earth were
farther away, we would be cooler.
11) during the preparatory reaction of aerobic respiration what happens to the carbon
molecules?
a. the carbon molecules are broken down from a 3-carbon to a 2-carbon acetyl group
and a 1-carbon co2 is released
b. the carbon molecules are broken down from a 4-carbon to a 3-carbon acetyl group
and a 2-carbon co2 is released
c. the carbon molecules are converted from a 2-carbon to a 3-carbon acetyl group and a
1-carbon co2 is consumed
d. the carbon molecules are broken down from a 3-carbon to a 1-carbon acetyl group
and two 1-carbon co2 are released
