Student provides an explanation for carbon dioxide fluctuations for different seasons of the year. ( 2 points)
jeka57 [31]

Carbon dioxide fluctuations occur for different seasons of the year due to the presence of plants in an area.

<h3>Why carbon dioxide fluctuations occur for different seasons of the year?</h3>

The carbon dioxide levels in the atmosphere moves up and down every year when plants use carbondioxide gas through the process of photosynthesis and respiration. Plants take up the carbondioxide gas in the spring and summer season and release it in fall and winter season. In this modern world, the level of carbon cycle is increasing because more carbon dioxide is emitted from burning fossil fuels and other human activities.

So we can conclude that carbon dioxide fluctuations occur for different seasons of the year due to the presence of plants in an area.

One form of chromatin modification is acetylation, which is known to occur on positively charged histone tail amino acids, thus
Naya [18.7K]

Answer:

A. The tails do not interact with the DNA

Explanation:

The acetylation refers to the transfer of the acetyl group from Acetyl-CoA to the N-terminal of the histone protein.

Lysine residues (positively charged amino acid) are present at the end of the N-terminal of the histone protein which is neutralized by the acetyl group.

This loses the compaction between the positively charged histone and the negatively charged DNA and the DNA becomes more relaxed. This relaxed state allows the transcription factors to easily bind the DNA and therefore the DNA becomes transcriptionally active.

Thus, Option-A is correct

Carbon is most abundant in the<br>Carbon is most abundant in the<br>and<br>and​
mihalych1998 [28]

Carbon is most abundant in the <u>atmosphere</u> and <u>hydrosphere</u>.  

Explanation:

In the atmosphere, carbon is mostly present in the gaseous state of carbon dioxide. Plants absorb atmospheric carbon through photosynthesis and prepare food which is used by other living organisms. Respiration by plants and animals returns carbon back to atmosphere.

Next to atmosphere, carbon is abundant in the hydrosphere dissolved in water. Aquatic plants and marine organisms absorb carbon dissolved in water to prepare food. This carbon is also used to produce shells and other marine structures.

Carbon is also present in lithosphere and biosphere.
