a) Use at least two examples to explain how technology has greatly increased food production in the world. Think about how different the way you get food is now from the way it was many years ago. b) What is a downside of each of these technologies? Think about harmful side effects that could result from the new developments. c) Give an example of how a society can have an effect on scientific research. Think about how the needs of a group of people may affect what scientists choose to study. d) Describe how science can have an effect on society.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

hope this !

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.

that is true   : ) hope this you
