Which of the following is a correct difference between active transport and facilitated diffusion?
sweet-ann [11.9K]

Answer:

Active transport requires energy from ATP while facilitated diffusion does not

Explanation:

Active transport and facilitated diffusion with the use of channel and carrier proteins are both ways by which ions, polar and large molecules cross a selectively permeable membrane.

The major difference is that; Active transport transport these particles from a low to high concentration, which is against concentration gradient and hence, energy is required to perform the task

Facilitated diffusion transport from a high to low concentration, which is through a concentration gradient and hence, no energy is required to perform the task.

Discuss how variations within the population affect survival and fitness using an influenza outbreak as a model to support your
Tcecarenko [31]

During an influenza outbreak, many people get infected and die. However, part of the population acquires immunity and survives. This is due to variations in the genotype and phenotype among individuals in the population. Probably a particular phenotype confers resistance to influenza. Therefore, this population is able to grow and develop to maturity and reproduce. Their genes are therefore passed over to subsequent generations.

The grasshopper doesn't have to use it circulatory system to carry gases to and from the grasshopper cells because the air that is passed through the trachea system is already close enough to get to the cells.

Explanation:

"In the grasshopper, exchange of oxygen and carbon dioxide occurs in the tracheal system. Hemolymph plays no part in the process. There is not even an oxygen-carrying pigment in insect hemolymph." - www.biology-pages.info
