1. Albino corn has no chlorophyll. You would expect albino corn seedlings
to
synthesize glucose indefinitely, using stored ATP and NADPH.
fail to thrive because they cannot capture light energy.
switch from the C4 pathway to the crassulacean acid metabolism
(CAM) pathway.
use accessory pigments such as carotenoids to capture light.
capture light energy in the white end of the visible light spectrum.
2. Most of the blood glucose entering the nephron returns to the plasma
by the process of...
osmosis in the loop of Henle
tubular excretion in the distal tubule
facilitated transport in the distal tubule
active transport in the proximal tubule
3. A new species of animal is discovered. These animals are nocturnal and
have exceptional night vision. Because they are generally not active
during the day, they did not develop the ability to see colors - they see
only black and white. Given this information, we can conclude that the
newly discovered animals likely have:
More rods than cones
Rods but no cones
Cones but no rods
More cones than rods
,4. If a person experiences limited movement at the atlanto-occipital joint,
what specific head motion would be most affected?
Nodding the head up and down
Opening and closing the mouth
Tilting the head to the side
Turning the head side to side
5. Describe the role of the atlanto-occipital joint in head movement.
The atlanto-occipital joint allows for nodding movements of
the head, enabling flexion and extension.
The atlanto-occipital joint connects the skull to the spine and
allows for rotation.
The atlanto-occipital joint connects the jaw to the skull.
The atlanto-occipital joint is responsible for lateral movements of
the head.
6. Describe the role of bile salts and bicarbonate in the digestive process.
Bile salts are produced by the pancreas, and bicarbonate is
produced by the stomach.
Bile salts are responsible for protein digestion, and bicarbonate
promotes enzyme activation.
Bile salts aid in the emulsification of fats, while bicarbonate
neutralizes stomach acid in the small intestine.
Bile salts and bicarbonate both assist in carbohydrate digestion.
7. What are the vas deferens?
short tubes that are formed from the union of the vas deferens
and the seminal vesicles
, small convoluted tubules in the testes where spermatogenesis
takes place
tubes that carry sperm from each epididymis to the urethra
structures that sits atop the testes and stores sperm
8. Describe how a gram stain can be used to differentiate bacterial
species.
A gram stain categorizes blood cells based on their size.
A gram stain differentiates bacterial species based on the
composition of their cell walls.
A gram stain highlights the nucleus in eukaryotic cells.
A gram stain identifies plant cell types.
9. Which of the following substances is known to exist as diatomic
molecules at room temperature?
Oxygen
Iron
Carbon
Neon
10. The [H+] of an acid solution that has a pH of 3 is:
1 x 10^3 M
1 x 10^11 M
1 x 10^-3 M
1 x 10^-11 M
, 11. Describe the significance of diatomic molecules in relation to oxygen's
role in biological systems.
Diatomic molecules do not play a role in biological systems.
Diatomic molecules are unstable and do not exist at room
temperature.
Diatomic molecules like oxygen are essential for respiration in
aerobic organisms.
Diatomic molecules are only found in metals.
12. If a person has damaged valves in their veins, what potential health
issue could arise from this condition?
Anemia
Varicose veins
Atherosclerosis
Hypertension
13. Which part of the brain is involved with coordinating balance and
motor function?
Medulla
Cerebrum
Pons
Cerebellum
14. What specific function do guard cells serve in relation to plant
physiology?
Regulation of water loss through transpiration
Movement of nutrients from soil to the plant
