Front

What are lipids and carbohydrates made of?

Back

Both consist of carbon, hydrogen, and oxygen, but carbohydrates have repeating structural units and lipids do not.

Front

How do you replicate a DNA strand?

Back

To replicate the DNA strand AATCATGGA, the complementary strand is TTAGTACCT.

Front

What is facilitated diffusion?

Back

Facilitated diffusion is a type of passive transport that requires specific proteins to help move substances across a cell membrane.

Front

What can be inferred from similar larval stages in marine worms and mollusks?

Back

They share a common ancestor.

Front

What is the purpose of DNA strand 'A'?

Back

To serve as a template for the synthesis of mRNA.

Front

What are the main components of lipids?

Back

Lipids are primarily made of fatty acids and glycerol.

Front

What is the role of carbohydrates in living organisms?

Back

Carbohydrates provide energy and serve as structural components in cells.

Front

What is the difference between active transport and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the sites where amino acids are assembled into proteins.

Front

What is the significance of a common ancestor in evolutionary biology?

Back

A common ancestor indicates that different species have evolved from a shared lineage.
