Explanation:
Active transport refers to the movement of materials across the cell membrane against concentration gradient.
The cell membrane remains intact. However, energy is required from within the cell to move materials into the cell against concentration gradient, hence the answer.
The genes encoded in your DNA result in the production of proteins that perform specific functions<span>within your cells. Various environmental factors and spontaneous events can lead to changes in genes.</span><span>These changes, called mutations, can lead to alterations in the structure and activity of the proteins your</span>cells use in their daily activities. In other words, changes to your genotype can result in changes to your<span>phenotype. We all have mutations in most of our body cells—yet we are, for the most part, normal and</span><span>functional human beings. </span>
