True
Explanation:
The DNA is the structure in living organisms that encodes genetic information.
DNA = DeoxyriboNucleic Acid.
- The DNA is made up of a double helix structure of two strands.
- It is made up of a phosphate group,deoxyribose sugar and four nitrogenous bases.
- The DNA is contained in the nucleus of every cell.
- Crick and Watson suggested the molecular structure of the DNA to be a double helix shape.

Answer:
b) Silicon and oxygen
Explanation:
A compound is a pure substance that contains two or more atoms chemically joined together. Sand is regarded as a 'compound' because it is made up of two or more atoms that are chemically bonded to one another.
Sand is said to predominantly contain silica, which has a chemical formula of SiO2. Hence, sand can be said to be a compound containing one atom of silicon (Si) and two atoms of oxygen (O2).
Nuclear chemistry is the study of reactions that involve changes in nuclear structure. The chapter on atoms, molecules, and ions introduced the basic idea of nuclear structure, that the nucleus of an atom is composed of protons and, with the exception of
Answer:
There are many opportunities a chemist, chemical engineer, and molecular biologist may have. These professions and or practices could become Product Development Scientists, a Clinical Pharmacist, a Biochemist, or a Pharmaceutical Administer. These careers are very important, because people with professions in these areas will be able to get well paying jobs that will most likely have increasing value over time.
Schools need to offer chemistry so people seeking jobs in these areas will be able to do what they love, and for those who are seeking other science related professions like becoming nurses and other important members in the work force, will be able to get the education they need. Chemistry is a college level class, and is a college credit. If you're not seeking a higher profession in the scientific area, you can take it to get a required credit out of the way.
There are a plethora of science jobs out there that are crucial to the wellbeing of people, and these jobs will ALWAYS be important.
This isn't five minutes... but I hope this helps a little. Add a lil' bit more, and you should be good. I really hope this helped.
