which best describes seeds and their role in the alteration of generations life cycle?

Answer:

Nucleotides are exclusively added to the 3' end of the developing strand when DNA is produced in the 5'-to-3' orientation. The 5'-phosphate group of the new nucleotide attaches to the 3'-OH group of the final nucleotide of the developing strand.

At the 3' end of the deoxyribose sugar, an upcoming nucleotide is added. The existing nucleotide's 3'-OH end and the new nucleotide's 5' phosphate make a phosphodiester bond. In this way, new nucleotides are added.

The DNA is made up of nucleotides. Each nucleotide of DNA is made up of a deoxyribose sugar, a phosphate group, and a nitrogenous base. Nitrogenous bases include adenine, guanine, cytosine, and thymine. The sugar of the DNA has a lack of oxygen at the 2' end. A glycosidic bond connects the sugar's 1' end to the nitrogen base.

The 5' end of sugar is attached to the phosphate group. The 3' end of sugar is attached to the 5' phosphate of the new upcoming nucleotide. A phosphodiester bond is formed during the addition of new nucleotides. Two phosphate groups of the new nucleotides are removed. Example: If ATP comes, then it will make AMP and attach to the DNA chain.

Hence, at the 3' -OH end of sugar of the existing nucleotides, a new one is added.

Answer:

i think its C) Freezing of perma frost

Explanation:

The option that does not describe a source of greenhouse gases is the freezing of glaciers. Thus, the correct option is C.

Greenhouse gases may be defined as those gases that are present in the earth's atmosphere and trap the heat and radiation from the sun and emitted toward the earth.

Such greenhouse gases are responsible for the greenhouse effect that ultimately leads to global warming.

Steaming and burning of fossil fuels and emissions from landfills extremely liberated the high amount of carbon dioxide in the atmosphere which is one of the most potent greenhouse gas.

Therefore, the option that does not describe a source of greenhouse gases is the freezing of glaciers (hailstone). Thus, the correct option is C.

Answer:

Its width.

Explanation:

The size of pyrimidines and purine is different because each group has a different structure (1 or two rings). Therefore, the width of DNA is "constant".

If we would pair two pyrimidines or two purines, the width of DNA would be different in both cases.

ATP is the energy currency of the cell and it is required almost everywhere. 4 cellular activities that would require the energy of ATP will be cellular respiration, ion transport, muscle contraction, nerve impulse.

The role of ATP is providing energy where it  gets hydrolysed into ADP along with the phosphate ion where the reaction provides energy and this reaction brings about energy in the activity.

The cellular activities are the activities that take place inside the cell and various activities that will link to them in order to perform various functions. DNA synthesis, biochemical reactions, cellular respiration, cellular activities all takes place with the help of ATP.

Therefore, ATP is required almost everywhere in both cellular respiration activities and cellular activities.
