Answer:

Because DNA molecules are extremely long.

Explanation:

DNA molecule is made up of only four types of nucleotides that are adenine, guanine, cytosine, and thymine. These four types of nucleotide encode all the information necessary for the formation and working of the entire organism because each DNA strand is as long as 2 meter which contains millions of base pairs.

The four nucleotides are arranged in the DNA strand with many different combinations which results in the formation of codons sequence that contains all the information about the cell. This long DNA is compressed several times to fit in the nucleus.

Answer:

Molecules are extremely long.

Explanation:

The genetic material may be defined as the material that can be transferred from parents to the offspring. DNA is the main genetic material of the living organisms but RNA acts as the genetic material in some viruses only.

The four different bases present in DNA are adenine, thymine, guanine and cytosine. The arrangement of these molecules is quite different in different species that brings variation in the living organisms. The DNA molecule is quite long that encode the information for the entire organisms.

Thus, the answer is molecules are extremely long.

Once a standard curve has been prepared by plotting numbers of bacteria (CFU/mL) versus absorbance for one species of bacteria,
Vika [28.1K]

Answer:

b. False

Explanation:

The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.

A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.

  • The rate of bacterial cell reproduction varies from a particular species to another.
  • Varying species have different absorbance thresholds.

Why is the nitrogen cycle important for living things?
slava [35]

Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food as part of these life processes, nitrogen is transformed from one chemical form to another. The transformations that nitrogen undergoes as it moves between the atmosphere, the land and living things make up the nitrogen cycle.


so i would choose b or c hope this helps

Why is it important for a cell to perform checks after DNA replication?
zimovet [89]

Answer:

A. If errors are not removed from areas with a gene, then the resulting proteins could be affected.

Explanation:

Since the genes in DNA contain instructions for the synthesis of proteins, any mistakes in areas of a gene will change how proteins are made.

It is important for cells to perform checks in order to catch these mistakes, because otherwise, RNA will be carrying the wrong instructions to create a protein.
