Answer:
The organisms that are the most reproductively fit.
The correct answer is option D, that is, Jon is correct because the respiratory system removes waste from the body by ridding it of carbon dioxide when we exhale, and the digestive system removes waste from the body in the large intestine where the waste is sent and removed through the rectum.
The respiratory system functions to provide adequate oxygen for the proper functioning of the body and at the same time works to remove the waste products like carbon dioxide via the process of exhalation.
On the other hand, the function of the digestive system is digestion and absorption. It digests the food components into smaller pieces, and helps in the absorption of nutrients from the food, the leftover undigested food, or waste is excreted out through the rectum. Hence, both respiratory and digestive system exhibits one common function of excretion of waste materials.
A DNA molecule is made up of nucleotides.Each nucleotide is made up of a nitrogen base, a sugar molecule and a phosphate group. There are 4 nitrogen bases such as adenine and guanine known as purines, thine and cytosine are known as pyramidine. These nitrogenous base are arranged in a sequence attached to each other by hydrogen bonding into anti-parallel strands. Therefore, the structure of DNA is termed as the double helical model.
The answer is d clinical deficiency
