Scientists use transgenic organisms to produce large amounts of human insulin in labs. Which action should be the first step in making a transgenic organism that can produce human insulin? A. Find an organism with a gene similar to the one for human insulin.

B. Insert a gene similar to the one for human insulin into a bacterial cell.

C. Insert the gene for human insulin into humans who need insulin.

D. Find the gene for insulin in a human's DNA.

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.  

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
