It differs from DNA chemically in two respects: (1) the nucleotides in RNAare ribonucleotides—that is, they contain the sugar ribose (hence the name ribonucleic acid) rather than deoxyribose; (2) although, like DNA,RNA contains the bases adenine (A), guanine (G), and cytosine (C), it contains the base uracil (U) .
Convection cell in the sun's rays are the ones that carry energy to travel within its surface and outside.
There are three types of heat transfer or heat propagation; conduction, convection and radiation. Heat transfer is the process by which heat projects externally however, depending on the temperature and pressure. Also called the movement of heat from a low temperatured state which increases as heat progresses.
Conduction is the heat transfer by contact, immediate contact.
Convection is the transfer of heat through air and water.
<span>Radiation is the transfer of heat regardless of the presence of atoms or particles. </span>
Answer:
The sides of the ladder are made of alternating sugar and phosphate molecules. The sugar is deoxyribose. The rungs of the ladder are pairs of 4 types of nitrogen bases. Two of the bases are purines- adenine and guanine.

<u>Advantages</u>:-
Following mentioned are a few enlisted positive effects (of using windmills):
• It is cost-free; in other words it is inexpensive or affordable.
• In fact it is and can be an alternate for fossil fuels.
• Moreover, wind energy is a domestic source of energy.
• It helps in controlling air pollution which is a huge threat to life.
• Furthermore, it utilizes merely a small amount of land the rest of which can be used by farmers wisely.
