Answer:
- Oxygen
- The body cells
- Producing energy
Explanation:
We breathe in oxygen from the external environment. Oxygen passes into our lungs and is passed into the blood capilaries. Here it is carried to all the cells throughout the body.
It diffuses into the cells and is necessary for the final stages of energy production by aerobic respiration. Therefore, it is necessary for powering all cellular processes.
During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!
I just did this BTW. The correct answer is A.) Nuclear fusion is the correct answer. Nuclear fission is what we use today in nuclear power plants, a great deal of radioactive waste, the other are by products of this process. Nuclear fusion releases a great deal of energy with a little radioactivity, but the problem is ignition temperatures; but maybe someday.
Answer:
B: only amino acids join together with peptide bonds to form proteins.
The sequence of sub units in a protein is most directly dependent on the DNA in the chromosomes in a cell
Answer: Option B
<u>Explanation:</u>
Any life events that takes place in a cell depends upon the central dogma of life that is the DNA getting transcribed into RNA and the RNA getting translated into protein, therefore we can conclude that the sequences of amino acids are based on the sequences of DNA that are present inside the chromosomes that are packed in a nucleus of a cell.
