Which of the options below correctly identifies the differences between RNA ands DNA? 1, DNA is single stranded, RNA is double stranded AND DNA uses Uracil while RNA uses Thymine

2, DNA is double stranded, RNA is single-stranded AND DNA uses Uracil while RNA uses Thymine

3, DNA is double stranded, RNA is single-stranded AND DNA uses Thymine while RNA uses Uracil

4, DNA is single stranded, RNA is double stranded AND DNA uses Thymine while RNA uses Uracil

answer; i believe its echoic memory,it is believed to last three to four seconds; good luck

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
