Biology Semester A Final Exam Review

Front

What gas is removed from the atmosphere during photosynthesis?

Back

Carbon dioxide is the gas removed from the atmosphere during photosynthesis.

Front

Which nitrogenous base is found in RNA but not in DNA?

Back

Uracil is the nitrogenous base found in RNA but not in DNA.

Front

What biomolecule is synthesized in photosynthesis and converted to ATP during cellular respiration?

Back

Glucose is the biomolecule synthesized in photosynthesis and converted to ATP during cellular respiration.

Front

What are the possible phenotypes from a cross between individuals with blood types AO and BO?

Back

The possible phenotypes are AB, A, B, and O.

Front

In an experiment, if plants are watered more than normal, what is the dependent variable?

Back

The dependent variable is the growth of plants.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to synthesize foods with the help of chlorophyll, converting carbon dioxide and water into glucose and oxygen.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

Define phenotype.

Back

Phenotype is the observable physical or biochemical characteristics of an organism, determined by both genetic makeup and environmental influences.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is the green pigment in plants that absorbs light energy, primarily from the sun, to drive the process of photosynthesis.

Front

What is the difference between DNA and RNA?

Back

DNA contains the sugar deoxyribose and the base thymine, while RNA contains the sugar ribose and the base uracil.
