The correct answer is C. Apple

Explanation:

An organism is a living individual which can reproduce, grow, react, adapt, move, metabolize and have an organized structure. All organisms are living things.  

Apple is a fruit that is non-living, it can not reproduce, it does not have an organized structure that can support life in it so apple do not contain any characteristics of life, therefore, it cannot be classified as an organism.

Lizard, trees, and bacteria are organisms because they satisfy all the characteristics of an organism. Therefore the right answer is C. Apple.  

many other transport proteins, often called pumps, move materials against a concentration gradient. active transport drives molecules across a membrane from a region of lower concentration to a region of higher concentration. this process, shown in figure 5.1, uses transport proteins powered by chemi- cal energy.
