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.

What should an
ecologist measure in order to construct a pyramid of biomass for an ecosystem?
•
A. the biomass in
each trophic level of the food web
•
B.
the total mass of all the organisms in a representative area of the ecosystem
•
C. the total mass of all the organisms in the ecosystem
•
D. the number of organisms in each trophic level of the food web
Answer:
A
Explanation:
This overcomes the size difference problem because all kinds of organisms at a trophic level are weighed.
Organisms are classified as producers if they are able to
(1) remove oxygen from the air
(2) remove microbes from the soil
(3) make their own food
(4) make carbon dioxide
Answer:
3. make their own food
they are normally the bottom of the food web or food chain they provide for other organisms and thrive by themselves like plants

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. As the reef significantly depends on these fishes and the lionfish feeds on these fish species, the lionfish destroy the reef.
1. Describe where genes are located and the function of genes.
Type your answer here: Genes are located within the Cells
2. Describe how changes (mutations) to genes can result in changes to proteins.
Type your answer here:
Explanation:
1 Genes are contained in chromosomes, which are in the cell nucleus.
2 Sometimes, gene variants (also known as mutations) prevent one or more proteins from working properly. By changing a gene's instructions for making a protein, a variant can cause a protein to malfunction or to not be produced at all.

Answer:
Adaptive Radiation
Explanation:
Evolution of an animal or plant group into a wide variety of types adapted to specialized modes of life. Adaptive radiations are best exemplified in closely related groups that have evolved in a relatively short time.

The USGS website from the Try It states, "We need to take the statement "Water is the universal solvent" with a grain of salt (pun intended). Of course it cannot dissolve everything, but it does dissolve more substances than any other liquid, so the term fits pretty well. Water's solvent properties affect all life on Earth, so water is universally important to all of us."
Water's solvent properties also affects Earth's non-living materials and surface features such as rocks, mountains, valleys, or caves.
Detail a plan for how you would conduct an investigation to answer the following question:
How does water's ability to dissolve more substances than any other liquid affect rocks in my neighborhood?
A rabbit’s cells include many carbon-based molecules, such as DNA and proteins. Which statement best explains how a rabbit obtains the carbon that it incorporates into its cells?
Choose one answer
(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.
What happens when you add food as a selection factor??
Answer:

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.

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.

Explain how the data support the claim that cysteine is a large polar molecule.
The data supports the claim that cysteine is a large polar molecule because concentration of cysteine is affected by mutant allele.
What is a Polar molecule?This is defined as a molecule which has a slightly positive end and a slightly negative end.
Cysteine is a large polar molecule because concentration of cysteine is affected by mutant allele therefore if complex protein is low, cysteine is not transported back and its concentration in urine is higher.
