17. Explain how carbon reservoirs can
be accessed without the influence
of humans.
Answer:Without human interference, the carbon in fossil fuels would leak slowly into the atmosphere through volcanic activity over millions of years in the slow carbon cycle. ... About half of these emissions are removed by the fast carbon cycle each year, the rest remain in the atmosphere.
Explanation:Hope this helps you!
In the slow carbon cycle, volcanic activity would release fossil fuel carbon into the atmosphere over millions of years without human intervention. The rapid carbon cycle removes half of these emissions annually, leaving the rest in the atmosphere.
What are 4 carbon reservoirs?
These are the reservoirs or sinks that carbon moves through as it cycles through the environment. Carbon is returned to the atmosphere through a wide number of different processes, including the decomposition of organisms, the eruption of volcanoes and fires, the combustion of fossil fuels, and more.
Carbon reservoirs contain substantial quantities of carbon between processes.
Burning fossil fuels such as natural gas, coal, and oil releases CO2, which is damaging to the environment and to individuals.Therefore, the carbon stocks such as fossil fuels have been used by humanity.

O b. polysaccharides; amino acids
c. amino acids; proteins
d. proteins; nucleotides
nucleic acids; nucleotides
e.
Answer:
B
Explanation:
An example of chemical digestion is the breakdown of nucleic acids, or nucleotides, which is in option e. Chemical digestion involves the breakdown of large, complex molecules into smaller ones, so here the correct option is option e.
Chemical digestion is a process that occurs in the digestive system, specifically in the stomach and small intestine, where complex macromolecules are broken down into smaller, simpler units through chemical reactions facilitated by digestive enzymes. Proteins are large macromolecules made up of chains of amino acids. Hence, here the correct option is option e.

Which statement describes the best evidence that two species share a recent common ancestor?
A) The species are about the same size.
B) The species eat the same type of food.
C) The species live in the same ecosystem.
D) The species have similar DNA sequences.
Answer:
I hope this helps you :)
Explanation:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
The statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D, as the DNA is the genetic material.
What role does the DNA sequence play in evolution?DNA sequence comparisons have become an increasingly important tool in determining evolutionary relationships between organisms, and after comparing the DNA sequences of different organisms, scientists can determine the degree of similarity between them such as similarities in size, diet, or ecosystem may indicate some degree of similarity between two species, but they do not necessarily provide evidence for a recent common ancestor.
Hence, the statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D.

Coniferous trees flourish because they take the opposite approach of deciduous trees: they grow (slow/fast) and die (young/old). Question 4 options: fast, young slow, young slow, old fast, old
Answer:
D. Coniferous and Deciduous trees
Explanation:
These trees are found in the humid subtropical climate areas.
Correct on edg. 2020
Coniferous trees grow slow and die old as compared to Deciduous trees.
What do you mean by Coniferous trees?Coniferous trees may be defined as mostly evergreen trees and shrubs having usually needle-shaped or scalelike leaves and including forms with true cones and others with an arillate fruit.
Deciduous trees tend to grow faster than evergreen trees. They have broader leaves as compared to evergreen trees. Coniferous trees have needles instead of leaves. They don't change color in the fall.
Therefore, Coniferous trees grow slow and die old as compared to Deciduous trees.

RNA contains instructions to make a specific protein and is produced from genetic information in the nucleus of the cell. This process is called translation. Therefore, option C is correct.
What is translation?The translation is the creation of a polypeptide chain from mRNA codons. The process is broken down into four steps: tRNA charging, initiation, elongation, and termination. mRNA is made from DNA by transcription, and then protein is formed from mRNA by translation.
The process of translating mRNA into the chain of amino acids that makes up the produced protein occurs in ribosomes in the cytoplasm of the cell.

Both prokaryotic and eukaryotic cells use ________ to turn certain genes on or off.
Group of answer choices
RNA polymerase
enhancers
activators
Both prokaryotic and eukaryotic cells use RNA polymerase to turn certain genes on or off. The correct option is A.
What is RNA polymerase?RNA polymerase, or more specifically DNA-directed/dependent RNA polymerase, is a molecular biology enzyme that synthesizes RNA from a DNA template.
The RNA polymerase enzyme is a large complex composed of many subunits. The prokaryotic RNA polymerase has four subunits that can transcribing all types of RNA.
These enzymes in eukaryotes have eight or more subunits that aid in the attachment and processing of DNA during transcription.
RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is a molecular biology enzyme that synthesizes RNA from a DNA template.
RNA polymerase is used by both prokaryotic and eukaryotic cells to turn genes on and off.
