When DNA was synthesized using nucleotides marked with 100% 15N isotope, the entire double strand of DNA contained nitrogen with 15N. When this DNA was cultured with a supply of nucleotides composed of nitrogen that was 100% 14N, as the DNA underwent replication, the daughter DNA was composed of 50% 14N and 50% 15N. What happened next when replication of the 50-50 daughter DNA was cultured with a supply of 100% 14N nucleotides, in terms of the composition of the next generation of DNA? Choose all that apply.

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good

explanation:

b. read the phase at the intersection of any given temperature and pressure.

c is the correct answer hope this !

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds
