Because the deletion mutation would cause a frame shift in the DNA base sequence and hence would lead to the formation of new base triplets. As a result, the primary structure of the enzyme would be diffe...

Water molecules move down their concentration gradient, across the partially permeable cell membrane, from a high concentration to a low concentration. Osmosis continues until the concentration of water m...

In order for efficient gas exchange to take place, an exchange surface, such as the alveoli in the lungs, should have the following: a large surface area to volume ratio, so that diffusion can occur at a ...

Asexual reproduction occurs when the offspring comes from a single parent. This results in offspring with the same genetic composition as the parent. Sexual reproduction occurs when a male gamete and a fe...

The alveoli in the lungs have a high surface area to volume ratio that provide a higher rate of diffusion. They have very thin walls which are one cell thick that allow fast gaseous exchange between the a...
