carbon dioxide
d
water vapor
Question 3
What would happen if plants did not have enough carbon dioxide to engage in photosynthesis?

a
Plants would not be able to grow and produce oxygen for animals to breathe.
b
Plants would be able to grow and produce oxygen for animals to breathe.
c
Plants would not be able to grow but would be able to produce oxygen for animals to breathe.
d
Plants would be able to grow but would not be able to produce oxygen for animals to breathe.
Question 4

a
Cellular respiration, performed by both producers and consumers, makes oxygen.
b
Producers and consumers store and produce carbon compounds.
c
Producers produce carbon dioxide during photosynthesis.
d
Consumers produce carbon dioxide during photosynthesis.
Question 5
Directions: Look at the below model of photosynthesis and respiration.

a
Carbon dioxide and oxygen are released.
b
Heat energy is converted to light energy.
c
Oxygen and glucose are used to make energy.

a
burning . . . photosynthesis
b
fixation . . . decomposition
c
respiration . . . decomposition
d
decomposition . . . photosynthesis
Question 7
The Ultimate Guide to Guinea Pig Breeds, Markings and Colors – Kavee USA

In guinea pigs, rough coats (with lots of swirly cowlicks) are dominant over smooth coats. If a male homozygous dominant guinea pig is crossed with a female heterozygous guinea pig, what are the possible genotypes and phenotypes of the offspring? Complete the Punnett square and the percentages of rough and smooth coated offspring.

***Please follow all Punnett square rules to complete this question. (Letters and numbers, only)

Please use the following: Rough = R and Smooth = r


offspring 1 offspring 2
offspring 3 offspring 4

% rough

% smooth

Question 8
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
One of them is homozygous for type B blood.
b
One of them has a recessive gene for type O blood.
c
Both parents have a recessive gene for type O blood.
d
Both parents are homozygous for type B blood.
Question 9
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 10
ABO blood type groups are an example of __________________. This is where there is one gene, but that one gene can have several versions.

Polycythemia or Too Many Red Blood Cells

a
incomplete dominance
b
multiple alleles
c
dihybrid trait
d
polygenic inheritance
