Reggie owns a flower shop. He has a species of flowers, Flora spottist, that can grow in three form: yellow flowers (YY), blue fowers (BB), or flowers with yellow and blue spots (YB). Yellow and blue spots are the result of a heterozygous co-dominant trait.
Reggie’s notices that solid yellow Flora spottist are more popular than the other types, but Reggie only has one yellow flower plant. If Reggie wants to grow more yellow flowers plants, which parents should he choose if he wants the most yellow plants?

b)
Spotted flowers (YB) x Yellow Flowers (YY)
c)
Spotted fowers (YB) x Blue flowers (BB)
d)
Yellow Flowers (YY) x Blue flowers (BB)
13.
What is the primary function of this cell?
a)
Cellular communication
b)
muscle contraction
c)
waste disposal
d)
extraction of energy
14.
You catch the flue virus and are feeling horrible. In order to fight the infection, your muscles begin to shiver to raise your body temperature. Your blood vessles dialate (open up) to allow more nutrients to effected areas and encourage more white blood cells to travel to the infection.
Which body systems are working together in this example?
Which body systems are working together in this example?
a)
Digestive, Reproductive, and Skeletal
b)
Muscular, Nervous, and Integumentary
c)
Nervous, Immune, Endocrine
d)
Immune, Circulatory, Muscular
15.
You read a note from a mystery organism:
“I am a single-celled organism that often lives in or on your body. Only a few of me cause disease, but mainly I help with food digestion. Humans sometimes use me to process foods like yogurt. In addition, I have a cell wall but I do not have a nucleus.”
To which kingdom does this organism belong to?

16.
Severe acute respiratory syndrome (SARS) is an illness caused by a coronavirus. Symptoms including a high fever, headaches, and body aches typically occur two to seven days after infection by the virus. SARS is more serious in elderly patients. This information suggests that the reproductive cycle of the SARS virus is —
a)
lysogenic, because the virus is a coronavirus
b)
lytic, because the virus causes respiratory illness
c)
lysogenic, because the virus primarily affects older people
d)
lytic, because of the quick onset of symptoms after infection
17.
The figure above represents some levels of organization in multicellular organisms. Which term fits in the box marked “X”?
a)
cells
b)
organelles
c)
organs
d)
organisms
18.
The table shows the color distribution of a lizard population in an environment.
What conclusion can be drawn using only the information in the table?
What conclusion can be drawn using only the information in the table?
a)
Yellow lizards can move more quickly than red or brown lizards.
b)
Yellow lizards are more likely than brown or red lizards to survive to reproduce.
c)
Yellow lizards are most likely to be seen by predators.

Yellow lizards can use food sources that red and brown lizards cannot.
19.
Which feature might be used to distinguish secondary succession from primary succession?

When humans perspire, water, urea, & salts containing sodium are removed from the blood. Drinking water during extended periods of physical exercise replenishes the water but not the sodium. This increase in water dilutes the blood & may result in the concentration of sodium dropping low enough to cause a condition known as hyponatremia.The best way to prevent hyponatremia would be to…
a)
drink more water
b)
eat chocolate
c)
eat salty foods
d)
drink cranberry juice

Many plants in the rainforest (lots of rain) have broad, wide leaves, while plants found in dry grasslands (little rain) typically have thin, narrow leaves.
What could account for the differences found between these plants?
What could account for the differences found between these plants?
a)
Plants in the rainforest have adapted to take advantage of higher levels of rainfall.
b)
Plants in the grasslands have adapted to not compete and share the sunlight.
c)
Narrow leaves meant the plants in the grasslands do not have any herbivores to eat them.
d)
Wide leaves mean the plants in the rainforest can save water for dry seasons.
22.
The outermost layer of plant stems in dicotyledons consists of epidermal cells and guard cells that surround openings called stomata. The epidermal cells are usually covered with a waterproof layer that provides protection from injury and water loss. The stomata allow for gas exchange. The epidermal cells and stomata have functions similar to those of which two human body systems?

Cardiovascular and Skeletal
c)
Respiratory and integumentary
d)
Cardiovascular and muscular

a)
One with a great deal of genetic diversity
b)
One with plants and animals but no bacteria
c)
One with animals and bacteria but no plants

If transpiration stopped completely, how would a plant's homeostasis first be affected?
a)
More carbon dioxide molecules would be taken in by the leaves.
