degree of environmental damage that can be attributed to fossil fuels. ... development of renewable energy sources such as, solar power, wind, ... the earth, yet it is enough to provide all of the earth's energy needs.
<h2>
ANSWER:</h2>
16 protons and 19 neutrons
<h2>
EXPLANATION:</h2>
The atomic number or proton number of a chemical element is the number of protons located in the nucleus of an atom. It is same as the charge number of the nucleus
Sulfur possesses an atomic number of 16, so it owns 16 protons.
protons + neutrons = atomic weight,
35-16=19. So sulfur has 16 protons and 19 neutrons

Answer:
b. False
Explanation:
These components are not sufficient to successfully perform a PCR reaction. Deoxynucleoside triphosphates (dATP, dGTP, dCTP, dTTP) are missing so that the PCR reaction can occur perfectly.
The PCR technique allows a specific fragment of the DNA molecule to be amplified thousands of times in just a few hours. This technique revolutionized research in molecular biology because it had taken a long time for DNA amplification. From PCR it is possible to obtain enough copies of a part of DNA to detect and analyze the sequence that is the target of the study.
For a PCR reaction to be performed a solution with some components must be prepared. These components are:
- Magnesium chloride buffer (to optimize reaction and act as a cofactor for polymerase)
- Forward and reverse primers (to customize the start of the enzyme reaction)
- DNA polymerase (Enzyme required for replication of desired DNA region.)
- DNA Template (the DNA to be copied)
- PCR-grade water
- Deoxynucleoside triphosphates: dATP, dGTP, dCTP, dTTP (act as bricks in the construction of DNA molecules).
