Question

an example of mitosis at work is a leaf turning yellow. growing. taking in carbon dioxide. performing photosynthesis.

Explanation:

Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus. It is crucial for growth, repair, and asexual reproduction. A leaf growing involves cell division (mitosis) to increase the number of cells, which leads to an increase in the size of the leaf. A leaf turning yellow is usually due to a change in pigments (like chlorophyll breaking down) rather than mitosis. Taking in carbon dioxide is part of the process of photosynthesis (a biochemical process, not directly related to mitosis). Performing photosynthesis is a metabolic process that uses light energy to convert carbon dioxide and water into glucose and oxygen, which is not about cell division (mitosis).

Answer:

growing.
