Semester 1 Review (Bio)

Front

What is surface tension?

Back

Surface tension is the cohesive force between liquid molecules at the surface, allowing objects to float on the surface without sinking.

Front

What organelle is responsible for producing ATP?

Back

Mitochondria are the organelles that produce energy in the form of ATP through cellular respiration.

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize a barren environment, such as lichen on bare rock.

Front

What is the function of the ribosome in protein synthesis?

Back

Ribosomes are the cellular structures that synthesize proteins by translating messenger RNA (mRNA) into amino acid sequences.

Front

What is the role of the rough endoplasmic reticulum?

Back

The rough endoplasmic reticulum is involved in the synthesis and processing of proteins, as it is studded with ribosomes.

Front

What is the function of the Golgi body?

Back

The Golgi body modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What are nucleic acids?

Back

Nucleic acids, such as DNA and RNA, are biomolecules that store and transmit genetic information.

Front

What is cohesion in the context of water?

Back

Cohesion is the attraction between water molecules, which contributes to surface tension.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and stores genetic information, while RNA is single-stranded and plays a role in protein synthesis.

Front

What is the function of lysosomes?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.
