Biology EOC Practice #9

Front

What is the function of autotrophs in the carbon cycle?

Back

Autotrophs use carbon dioxide to produce glucose through photosynthesis.

Front

What is the role of transfer RNA (tRNA) in protein synthesis?

Back

tRNA carries amino acids and helps assemble them as directed by mRNA.

Front

What is a keystone species?

Back

A keystone species is one that has a disproportionately large effect on its environment relative to its abundance.

Front

What happens to water in swollen gums when rinsed with salt water?

Back

The water in the gums has moved from a high to a low concentration of water due to osmosis.

Front

What is a plasmid?

Back

A plasmid is a small, circular piece of DNA that can replicate independently of chromosomal DNA in bacteria.

Front

What is transgenic bacteria?

Back

Transgenic bacteria are bacteria that have been genetically modified to contain genes from other organisms.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which autotrophs convert light energy into chemical energy in the form of glucose.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into amino acid sequences.

Front

What is osmosis?

Back

Osmosis is the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.

Front

What is the significance of the sea otter in its ecosystem?

Back

Sea otters are a keystone species; their presence or absence significantly impacts the structure of the coastal ecosystem.
