Biology FALL Semester Day 2 Review 24-25

Front

What is osmosis?

Back

The movement of water molecules across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What happens to a cell in a hypotonic solution?

Back

Water enters the cell, causing it to swell and potentially burst.

Front

What happens to a cell in a hypertonic solution?

Back

Water leaves the cell, causing it to shrink.

Front

What is the definition of isotonic solution?

Back

A solution where the concentration of solutes is equal inside and outside the cell, resulting in no net movement of water.

Front

What is enzyme denaturation?

Back

The process in which an enzyme loses its functional shape due to high temperature or extreme pH, rendering it inactive.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions without being consumed in the process.

Front

What is the energy transfer efficiency in food chains?

Back

Typically, only about 10% of the energy from one trophic level is transferred to the next level.

Front

What are producers in an ecosystem?

Back

Organisms that produce their own food through photosynthesis, such as plants and algae.

Front

What are primary consumers?

Back

Herbivores that eat producers, such as rabbits and deer.

Front

What are secondary consumers?

Back

Carnivores that eat primary consumers, such as foxes and birds of prey.
