What is Osmosis

Osmosis is the movement of gas molecules from an area of lower pressure to an area of higher pressure through a semi-permeable membrane.

Osmosis is the movement of solid particles from an area of lower concentration to an area of higher concentration through a semi-permeable membrane.

Osmosis is the movement of solute molecules from an area of higher solute concentration to an area of lower solute concentration through a semi-permeable membrane.

Osmosis is the movement of solvent molecules from an area of lower solute concentration to an area of higher solute concentration through a semi-permeable membrane.

What is active transport

Passive movement of molecules without using energy

The process of breaking down molecules in the cell

Movement of molecules within the cell using energy

What is passive transport

Movement of substances within the cell

Movement of substances with the need for energy input

Movement of substances across cell membranes with the help of enzymes

Movement of substances across cell membranes without the need for energy input

What is the concentration gradient?

Sudden change in the concentration of solutes in a solution between two regions

The absence of solutes in a solution

The concentration of solutes in a solution remains constant throughout

The equilibrium in the concentration of solutes in a solution between two spaces

What is cancer and distinguish between malignant and benign

Malignant tumors invade and destroy nearby tissue, while benign tumors do not invade or spread

Malignant tumors are easily treatable, while benign tumors are difficult to treat

Malignant tumors are always small in size, while benign tumors are always large

Malignant tumors are caused by bacteria, while benign tumors are caused by viruses

What happens if cells ignore cell signals?

The body will become more resistant to diseases

The immune system will be strengthened

Cancer may develop

Cells will function normally

10.

What are cyclins?

Proteins that control the progression of cells through the cell cycle

Carbohydrates that provide structure to cells

Lipids that store energy in cells

Nucleic acids that carry genetic information

11.

What is apoptosis and why do cells carry it out?

Programmed cell death to remove damaged or unnecessary cells

Apoptosis is a result of cell mutation

Apoptosis is a response to repair damaged cells

Apoptosis is a process of cell division to increase cell population

12.

Osmosis is the movement of _____ across a membrane.

solute

gas

solvent

solid

13.

When both inside and outside of a cell have the same amount of water it is said that the cell has reached a state of

equilibrium

overload

imbalance

stagnation

14.

During osmosis

water molecules move from an area of low solute concentration to an area of high solute concentration

osmosis does not involve the movement of water molecules

osmosis only occurs in the presence of equal solute concentration on both sides of the membrane

water molecules move from an area of high solute concentration to an area of low solute concentration

15.

nucleus

cytoplasm

cell wall

cell membrane

16.

Water molecules move randomly in all directions

Water molecules do not move during osmosis

From an area of lower solute concentration to an area of higher solute concentration

hypotonic

acidic

hypertonic

isotonic

18.

During diffusion

diffusion requires energy input

diffusion only occurs in liquids

particles move from an area of low concentration to an area of high concentration

particles move from an area of high concentration to an area of low concentration

19.

disruption

equilibrium

imbalance

chaos

20.
