Question 1
Sarah has type A blood, and Jesse has type O blood. Their son has type B blood. Can Jesse be the baby daddy? He is a bit worried.
Please complete the Punnett squares to determine the possibilities.
a
Yes, if one parent is heterozygous
b
No, this is impossible
c
Yes, if both parents are heterozygous
d
No, type B blood must be homozygous
Question 2
White rabbit with black rabbit photo WP32787
In rabbits, black fur is dominant to white fur. As a rabbit breeder, you crossed a BB male with a Bb female, please complete the Punnett square for the possible genotypes of the offspring. Then complete, the percent chance for the phenotypes of the offspring.
***Please follow all Punnett square rules to complete this question.

Question 3
The diagram shows a summary of photosynthesis.
What substances do each of the letters represent?
a
W is O2; X is H2O; Y is CO2; and Z is glucose.
b
W is H2O; X is O2; Y is glucose; and Z is CO2.
c
W is CO2; X is O2; Y is H2O; and Z is glucose.
d
W is H2O; X is O2; Y is CO2; and Z is glucose.
Question 4
Dr Injectus treats an animal cell with a chemical that destroys the cell's mitochondria. As a result of his action, which of the cell's processes will most likely be stopped?
a
fermentation
b
photosynthesis
c
aerobic respiration
d
enzyme production
Question 5
The model shows part of how carbon is cycled between living organisms.
image b43ccec60a054a2dbf9c8b5eba8bc2a8
The (bottom) green box in the model represents organisms that remove carbon dioxide from the atmosphere to recycle it. Which BEST describes these organisms?
a
bacteria that combine carbon dioxide with nitrogen to make nutrients
b
consumers that make energy by taking in carbon dioxide when they inhale
c
producers that carry out photosynthesis to make carbon-rich sugars
d
fungi that break down oxygen and release carbon dioxide in exchange
Question 6
How would the carbon cycle be disrupted if human activities released an extremely large amount of carbon dioxide into the atmosphere?
a
Plants would have more difficulty engaging in photosynthesis, and a massive amount would die off.
b
Plants and animals in Earth's oceans would have more difficulty processing carbon dioxide, and carbonification would not occur in deep marine soils.
c
Animals would have more difficulty breathing, and it would be years before the air contained a healthy amount of oxygen.
d
Humans would have difficulty burning wood and fossil fuels, and it would take years before the air contained a healthy amount of bicarbonate (HCO3-).
Question 7
The model shows part of how carbon is cycled.

The green box in the model represents organisms that remove carbon dioxide from the atmosphere to recycle it. Which BEST describes these organisms?
a
producers that carry out photosynthesis to make carbon-rich sugars
b
bacteria that combine carbon dioxide with nitrogen to make nutrients
c
fungi that break down oxygen and release carbon dioxide in exchange
d
consumers that make energy by taking in carbon dioxide when they inhale
Question 8
Photosynthesis and cellular respiration are the driving biological forces behind which of the following cycles?
a
water cycle
b
carbon cycle
c
bi cycle
d
cell cycle
Question 9
Directions: Watch this video and then use the information below to answer any questions that follow.
There are three different alleles for blood-type: A, B, and O. A and B are dominant over O. If a person has A and B genes, he or she has blood-type AB. This is referred to as a codominant pattern of heredity.
Jane's mother and father have type B blood. When Jane's blood was tested, she found she had a blood-type of O. Select the best response from the options below.
Modes of Inheritance | BioNinja
a
Both parents are homozygous for type B blood.
b
One of them has a recessive gene for type O blood.
c
One of them is homozygous for type B blood.
d
Both parents have a recessive gene for type O blood.
Question 10
An extraterrestrial planet has organisms that reproduce with DNA the same way as organisms on Earth. A common organism dwelling on this planet have eyes that are either triangular or round. Triangular eyes (T) are dominant to round eyes (t). A Punnett square should be made to predict the offspring of two of these extraterrestrials with the genotypes TT and Tt.
What is the probability that an offspring would have triangular eyes?
a
0:4
b
1:4
c
2:4
d
3:4
e
4:4
Question 1: c) Yes, if both parents are heterozygous.
