What happens to carbon in plants when the plants die?(1 point)
The carbon is not released; it is lost.
The carbon will be released into the soil for use by the next generation.
The carbon is released into the air.
The carbon is released into the soil, but it is not used again.
Answers
Answer:
The carbon will be released into the soil for use by the next generation.
Explanation:
I finished the quiz and this was the correct answer.
When the plants die in that case the plants will die and the carbon from the body of the plants gets displaced in the soil. This is the end cycle of the nutrients of plants.
What is the location of carbon in plants ?It is the carbon compounds with the glucose containing the 6 number of carbons and the sugars containing total in 5 numbers of carbons.
As the plants gets the soil there body gets decomposed into the soil and later on the carbon that is absorbed from the atmosphere is given back to the soil and later on they together make the energy sources of carbon in the form of fossils which can be demonstrated later on as well.
And after plants get died, they get decayed by releasing carbon to atmosphere. The difference in the amount of carbon plants get absorbed and they do release is known as the net primary productivity. It is the direct measurement of the amount of how much plant matter is from the crops to the forests or ocean phytoplankton by the Earth produces.

While looking at a cell under a microscope, a scientist is able to see a biological molecule. This molecule is a nucleic acid with a ladder structure and contains the nitrogenous bases adenine, thymine, cytosine, and guanine. Based on this information, what conclusion can the scientist draw regarding this nucleic acid?
Answers
Answer:
Based on the information , the scientist concluded that the regarding nucleic acid is DNA (Deoxyribonucleic Acid) .The structure of DNA is attached below -:
Explanation:
PROPERTIES OF DNA -
In humans and almost all other species, DNA, or deoxyribonucleic acid, is an inherited substance. Almost every cell in the body of an individual has the same DNA. The DNA information is stored as a code consisting of four chemical bases: adenine (A), cytosine ( C), guanine ( G) and thymine ( T). In order to form units called base pairs, DNA bases pair up with each other, A with T and C with G. A sugar molecule and a phosphate molecule are both affixed to each base. Together, a nucleotide is called a base, sugar , and phosphate. Two long strands are arranged with nucleotides that form a spiral called a double helix. The double helix structure is much like a ladder, with the base pairs forming the rungs of the ladder and the molecules of sugar and phosphate forming the vertical sidepieces of the ladder.An significant DNA property is that it can duplicate itself or create copies of it. In the double helix, each strand of DNA will serve as a template for duplicating the sequence of bases. As each new cell requires to have an exact copy of the DNA present in the old cell, this is important as cells divide.Hence, the structure identified and conclude by the scientist is DNA (deoxyribonucleic acid). Thus, the structure of DNA is attached below.
Answer:
✓ The nucleic acid is DNA and would be found in the cell's nucleus
