The motion of molecules and the transfer of energy decreases with increase in volume of the solution.
What is effect of volume in motion of particles?The volume of a solution is inversely proportional to the motion of the molecules of a substance.
An increase in volume results in a decrease in the motion of particles due to a decrease in the frequency of particles and thus, less energy is transferred.
Therefore, the motion of molecules and the transfer of energy decreases with increase in volume of the solution.

(Choice A)
A
The rabbit eats grass, which contains carbon within its sugar molecules.
(Choice B)
B
The rabbit breathes air, which contains carbon in the form of carbon dioxide.
(Choice C)
C
The rabbit lives in a burrow in the soil, which contains various sources of carbon.
Answer:
A: The rabbit eats grass, which contains carbon within its sugar molecules.
Explanation:
Animals such as rabbits consume food, which is broken down into smaller components through digestsion. As part of the digestive process, nutrients from the food are absorbed into the bloodstream and carried to cells throughout the body. These components incorporated into the cell structures.
Which factor can decrease the rate of a chemical reaction?

Describe a hypothetical example showing how rising sea levels due to global warming might cause extinction.
Answer:
Global warming may cause more icebergs to melt than are created. This would lead to higher sea levels. Sea levels may rise above land masses located at low elevations. As a result, the animals who lived in these areas may find their habitats shrinking and resources depleting, causing their population size to decrease. If there are particular species that were only able to survive in the areas now covered by water, they may very well become extinct.

if a person is heterozygous for cystic fibrosis is married to someone who actually has the disease. What are the chances that their child will have CF?
Answer:
50%
Explanation:
CF is a recessive trait. That means that an individual must have two copies of the recessive allele in their genotype in order to express the trait. That means that the parent with CF has genotype cc, while the parent who is heterozygous, and does not express the trait, has genotype Cc. Using a Punnett square to demonstrate the cross of these two parents will produce a probability of 50% heterozygous and 50% positive for CF.

How did the lack of sea urchins change the effect of lionfish on the reef? Explain.
Explanation:
The lack of sea urchins causes the accumulation of algae on the reef leading to the growth of fish populations. The process significantly increased the invasion of lionfish in the reef.

Why do you think the class insecta is the largest group of arthropods and the most abundant group of eukaryotes?
Due to the morphology, characteristics, and diverse functions, the class Insecta is the largest group of arthropods and the most abundant group of eukaryotes.
What do you mean by Arthropods?Arthropods may be defined as a phylum of invertebrate animals that have a segmented body and jointed appendages, exoskeleton, and dorsal anterior brain.
Insects are found on the Earth since a very long time. They possess a protective shell of an exoskeleton, and their small size, and ability to fly allowing them to escape from their predators. They easily migrate from one region to the other where sufficient food is available.
Among eukaryotes, they occupy a large proportion because they have sufficient area to live, food to eat, and options for mating.
Therefore, due to the morphology, characteristics, and diverse functions, the class Insecta is the largest group of arthropods and the most abundant group of eukaryotes.
