Biology Fundamentals Quiz

The unifying themes in biology include the cellular basis of life, heredity and evolution, and the relationship between structure and function.

Like other scientists, biologists use the scientific method to make observations, pose questions, and test hypotheses.

Energy processing is important to life as it allows organisms to move, grow, and reproduce.

<p>Biologists can study life at multiple levels of organization, from the molecular biology of a cell to the anatomy and physiology of plants and animals, and evolution of populations.</p> Signup and view all the answers

<p>Photosynthesis is the biological process used by many cellular organisms to convert light energy into chemical energy. Its primary purpose is to store the chemical energy in organic compounds that can later be metabolized through cellular respiration to fuel the organism's activities.</p> Signup and view all the answers

<p>The byproduct of oxygenic photosynthesis is oxygen. Some of the chemical energy produced is stored in carbohydrate molecules such as sugars, starch, glycogen, and cellulose.</p> Signup and view all the answers
