2) which of the following is  not a possible outcome  of recombinant deoxyribonucleic acid (rdna) technology? a) increasing the production of hardier crops b) correcting a human disease c) estimating the age of a rock sample d) mass production of human hormones by bacteria 3) is a nucleic acid base found in ribonucleic acid (rna) but not in deoxyribonucleic acid (dna). a) cytosine (c) b) guanine (g) c) thymine (t) d) uracil (u) 4) which of the following transport mechanisms requires atp to move materials across a plasma membrane? a) osmosis b) facilitated diffusion c) simple diffusion d) active transport

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.

a. population growth is decreasing

-2

+4

-10

-3

-8

-3

so the population decreased by 24 because 3+3+8+10+2=26-2=24.
