HBIo 1st Quarter Semester Review (Ch 1,2,3,8,9)

Front

What is quantitative data?

Back

Quantitative data refers to numerical information that can be measured and expressed in numbers, such as length, height, weight, and temperature. Example: 6.84 cm.

Front

What is a primary function of proteins?

Back

Proteins serve various functions including acting as hormones and enzymes, building tissues and muscles, and transporting materials. They do NOT store and transmit genetic information.

Front

Where is the anticodon located?

Back

The anticodon is located on tRNA (transfer RNA), which helps in the translation of mRNA into proteins.

Front

What type of observation is explaining the color of a chemical?

Back

Explaining the color of a chemical is a qualitative observation, as it describes characteristics that cannot be measured numerically.

Front

What is hydrolysis?

Back

Hydrolysis is the process used to split polymers by adding water, breaking down complex molecules into simpler ones.

Front

What is qualitative data?

Back

Qualitative data refers to descriptive information that cannot be measured numerically, such as color, texture, and smell.

Front

What role do enzymes play in biological processes?

Back

Enzymes act as catalysts in biological processes, speeding up chemical reactions without being consumed in the process.

Front

What is the difference between DNA and RNA?

Back

DNA (deoxyribonucleic acid) stores genetic information, while RNA (ribonucleic acid) plays a role in protein synthesis and can act as a messenger.

Front

What is dehydration synthesis?

Back

Dehydration synthesis is a chemical reaction that combines two molecules by removing water, forming a larger molecule.

Front

What is the function of mRNA?

Back

mRNA (messenger RNA) carries genetic information from DNA to the ribosome, where proteins are synthesized.
