Answer:

d) alternating sugars and phosphates.

Explanation:

DNA is a molecule which acts as the genetic material of the organisms on Earth. The DNA is made of the monomer units called nucleotides which are composed of a sugar called deoxyribose, a phosphate group and two types of nitrogenous bases (purines and pyrimidines).

The DNA structure is known as the double-helical model which gives a ladder-like appearance in a twisted manner. The backbone of the ladder or DNA is made of the deoxyribose sugar and the phosphate group whereas the nitrogenous bases are arranged inside the DNA.

Thus, option-D is the correct answer.

ehidna [41]

Answer:

Breathing heavily after you have finished running a race is your body way of repaying an oxygen debt.

Explanation:

Any kind of exercise that is performed makes our muscles work harder. As a result, more calories get burned by these muscles. To burn the extra calories, more supply of oxygen is required by the muscles. As you exercise harder, the breathing increases and become heavier to bring more oxygen to the lungs. From the lungs, the oxygen is carried to the muscles which are burning more calories.

You breathe heavily at the end of a race to get enough supply of oxygen.
