1. Increased amounts of carbon dioxide in Earth's atmosphere may be leading to
A: increasingly rapid climate change.
B: more photochemical smog.
C: Formation of a hole in the ozone layer.
D: A decrease in the greenhouse effect.
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 not be able to grow but would be able to produce oxygen for animals to breathe.
C: Plants would be able to grow and 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.
The model shows part of how carbon is cycled between living organisms.
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: producers that carry out photosynthesis to make carbon-rich sugars
B: fungi that break down oxygen and release carbon dioxide in exchange
C: bacteria that combine carbon dioxide with nitrogen to make nutrients
D: consumers that make energy by taking in carbon dioxide when they inhale
A farmer is breeding two different types of plants with varying patterns of inheritance. For Plant Type A, the allele for red petals is (R) and the allele for white petals is (r). The farmer crosses a homozygous red plant with a homozygous white plant. For Plant Type B, the alleles for both red (R) and white (W) petal color are dominant. The farmer crosses a homozygous dominant red plant with a homozygous dominant white plant. The results of the farmer's crosses are shown in the Punnett squares.
A: Plant Type A shows a complete dominance pattern of inheritance, and Plant Type B shows a recessive pattern of inheritance.
B:Plant Type A shows a codominance pattern of inheritance, and Plant Type B shows an incomplete dominance pattern of inheritance.
C: Plant Type A shows an incomplete dominance pattern of inheritance, and Plant Type B shows a codominance pattern of inheritance.
D: Plant Type A shows a recessive pattern of inheritance, and Plant Type B shows a complete dominance pattern of inheritance.
On an extraterrestrial planet, which had organisms that reproduced with DNA the same way that organisms on Earth do, green little organisms have eyes that are triangular or round. Triangular eyes (T) are dominant to round eyes (t). A Punnett square was made to predict the offspring of two of these extraterrestrials with the genotypes Tt and tt. Use the Punnett square below to answer any questions that follow.
According to the Punnett square, 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
Photosynthesis and cellular respiration are the driving biological forces behind which of the following cycles?
A: water cycle
B: bi cycle
C: cell cycle
D: carbon cycle
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.
A: Both parents are homozygous for type B blood.
B: Both parents have a recessive gene for type O blood.
C: One of them has a recessive gene for type O blood.
D: One of them is homozygous for type B blood.
All living organisms contain carbon. As organisms grow, they require large quantities of carbon to carry out life processes and make new cells. Where is the source of most of Earth's available carbon?
A: New carbon atoms are constantly being created by the process of photosynthesis.
B: Carbon is constantly recycled from dead organisms back into the environment.
C: Carbon atoms are constantly transferred from the Sun to Earth along with sunlight.
D: Carbon is constantly transported from the mantle to the crust by volcanic eruptions.
The graphic shows a diagram of a carbon cycle that a student drew.
Which mistake did the student make in the diagram?
A: Animals do not release carbon dioxide into the atmosphere during respiration.
B: Carbon dioxide is not removed from the atmosphere during photosynthesis.
C: Plants do not remove carbon dioxide from the atmosphere during respiration.
D: Factory and vehicle emissions do not release carbon dioxide into the atmosphere.
Look at the below model of photosynthesis and respiration.
Based on the information in the model, what can the student conclude about cellular respiration?
A: Water is both a reactant and a product.
B: Oxygen and glucose are used to make energy.
C: Carbon dioxide and oxygen are released.
D: Heat energy is converted to light energy.

Also, a lot of your data is lacking. Cannot copy and paste here.
What are your choices?
However, I will give you a little help. Even without the Punnet square, half will have the dominant trait for eyes.
