DNA in the nucleus carries the genetic doe for making proteins in ribosomes in the diagram c is the process by wich DNA code is used to manufacture proteins what process is represented by c A:translation

B:transcription

C:transformation

D:protein replication

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.

d) a person who learns about the world by observing it.

explanation:

scientist are people who discover why and how things are done and made in the world.
