DNA is made up of six smaller molecules -- a five carbon sugar called deoxyribose, a phosphate molecule and four different nitrogenous bases (adenine, thymine, cytosine and guanine).
Nucleotides are the building blocks of nucleic acids; they are composed of three subunit molecules: a nitrogenous base, a five-carbon sugar (ribose or deoxyribose), and at least one phosphate group.
Because DNA is our genetic blueprint.
I believe The answer is <span>B.Observations generate a scientific question, leading to a hypothesis, which can be tested through an experiment.
Observation requires you to pay attention to occurrences around you until a certain question about why that occurrence happens. The hypothesis is your initial prediction on why that happens. The experiment is being done in order to collect data and analysis so you can test your hypothesis</span>
Im assuming you mean the light-dependent reaction? if so the answer is the 3rd one
Explanation:
There are two classes of nuclear reactions which are:
- Nuclear fission
- Nuclear fusion
In nuclear fission, a radioactive isotope which has a heavier nucleus spontaneously disintegrates(breaks up) into 2 lighter nuclei and several neutrons with a large release of energy.
A nuclear fusion occurs by the combination of small atomic nuclei into larger ones with the release of a large amount of energy.
I hope you can make the best choice from this explanation.
