Trees absorb the sun's energy without radiating it back into the atmosphere.
Trees drain greenhouse gases like methane from the
soil.

What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

Answers
Answer:
hope its not to late..............Samira's model correctly demonstrates how the properties changed with the rearrangement of the atoms. However not all atoms are accounted for. There is a missing reactant. Samira's model correctly demonstrated how the atoms in two compounds reacted to form two new products. However, the elements present in the reactants side should be the elements that make up the new products in the product side. But as the diagram shows, Sameera has mistakenly added a new element to one of her products which will be wrong.

What two enzymes are used during replication and what does each do?
Answers
Answer:
The two enzymes that are used during DNA replication is helicase and polymerase. Each enzyme has distinct role that made it a vital part of the replication. In the course of DNA replication, the initial stage is to unzip the double helix structure of the DNA molecule by the enzyme helicase, which breaks the hydrogen bonds that holds the complementary bases of DNA.
Moreover, the DNA polymerase has the ability to exactly copy a DNA template. This enzyme binds to the leading strand and then adding a new complementary nucleotide bases to the DNA strand. In addition, it catalyzes the joining of deoxyribonucleoside 5′-triphosphates (dNTPs) to form the increasing DNA chain.

Write an explanation of the relationship between genes, proteins, and traits for the Blue Lobster.
You may think of a lobster as red, but about 1 in every 2 million lobsters is blue! This blue color is the result of a mutation in the lobster’s genes. The mutation causes the lobster to make an extra amount of a protein called astaxanthin. This protein is usually important for the red color that you see when the lobster is cooked, but in excess amount, makes the lobster blue.
Answers
Answer: The lobster's blue coloration is a result of a genetic defect that causes the lobster to produce more of a certain protein than normal.

Why do scientists track virus mutations and how might tracking these variants be helpful in preventing and treating the virus?(coronavirus)
Answers
Answer:
Different variants = certain symptoms and effects of the virus that cannot be prevented by the "basic" or "original" vaccine. So tracking the different variants would allow scientists to also account for those effects when creating a 2.0 vaccine or treatment.
Scientists track the coronavirus and its mutations around the world to study and fight it properly.
The coronavirus is a virus that became a pandemic during 2020 that spread throughout most of the planet, infecting millions of people. People who acquired the virus had symptoms of respiratory infection such as
