Semester1 Biology Final Exam Quarter 1 Part 1 topics

Front

What is the function of DNA?

Back

STORES genetic information for producing proteins.

Front

Which part of the nucleotide determines traits and how closely related organisms are?

Back

Nitrogen bases.

Front

What is passive transport?

Back

The process of molecules moving from a high to low concentration across the cell membrane without using energy (ATP).

Front

What type of organisms perform cellular respiration?

Back

ALL living things.

Front

What is osmosis?

Back

The movement of water across a semipermeable membrane.

Front

What is the role of nitrogen bases in DNA?

Back

They determine the genetic code and traits of an organism.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy (ATP) to move molecules against their concentration gradient, while passive transport does not.

Front

What are autotrophs?

Back

Organisms that produce their own food, typically through photosynthesis.

Front

What are heterotrophs?

Back

Organisms that obtain their food by consuming other living things.

Front
