What are the chemicals for the two strands of nucleotides
Answer fast pleaseee
Answers
The chemical structure of DNA and its nucleotides The DNA double helix is composed of two strands of DNA; each strand is a polymer of DNA nucleotides. Each nucleotide consists of a sugar, a phosphate group, and one of four nitrogenous bases. The structure and orientation of the two strands are important to understanding DNA replication. Drag the labels to their appropriate locations on the diagram below. Use only the pink labels for the pink targets, and the blue labels for the blue targets. Labels can be used once, more than once, or not at all.
A cell that has 6 chromosomes in the G2 phase will have how many sister chromatids during that same phase
Answers
Answer:
12 chromatids.
Explanation:
If a cell has 6 chromosomes in the G2 phase will have 12 sister chromatids during that same phase because replication of chromosomes occurs which produces two exact copies of each chromosomes. Then 6 chromatids are distributed in one daughter cell while the other 6 chromatids are distributed in other daughter cell and finally the cell division occurs.

All living things must contain genetic material. Which of the following nonliving things also has this characteristic? A. Fire B. Cell phone C. Virus D. Organic phosphates
Answers
Genetic material is the hereditary unit found in the cells of every living organism. Viruses are nonliving things that also have genetic material. Thus, option C is correct.
What are viruses?Viruses are organisms that are living and nonliving as they reproduce when once inside the host cell and have the RNA or the DNA as the genetic material inside their capsids.
The protein shell of the virus includes one of the types of genetic material that infects the host DNA by taking control of the host machine to produce multiple copies.
Therefore, the virus is a non-living with genetic material.

Glucose is Key to keeping the mechanisms of the body in top working order. When our glucose levels are optimal, it often goes unnoticed. But when they stare from recommended boundaries, you’ll notice that unhealthy effect it has a normal functioning.
Oxygen is a colorless, oder less reactive gas, the chemical element of atomic number 8 and the life-supporting component of the air.
Mitochondria is an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to for layers and that’s called critstae.
In Units 4A and 4B, we have learned about photosynthesis and cellular respiration. Which of the following statements is true?
a. The reactants of photosynthesis are the reactants of cellular respiration.
b. Photosynthesis produces light energy while cellular respiration produces chemical energy.
c. The products of photosynthesis are the reactants of cellular respiration.
d. Photosynthesis and cellular respiration use light energy to convert to chemical energy.
Answers
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
