WHAT IS OSMOSIS?
THE MOVEMENT OF WATER
1 of 17
WHAT TYPE OF MEMBRANE IS THE CELL MEMBRANE?
SEMI PERMEABLE
2 of 17
DESCRIBE WHAT HAPPENS IN OSMOSIS
WATER DIFFUSES FROM A DILUTE SOLUTION TO A REGION WHERE THERE IS A LOWER WATER CONCENTRATION
3 of 17
WHAT IS ACTIVE TRANSPORT?
THE MOVEMENT OF SUBSTANCES AGAINST A CONCENTRATION GRADIENT USING ENERGY
4 of 17
HOW DO THE CELLS GET THE ENERGY FOR ACTIVE TRANSPORT?
RESPIRATION
5 of 17
DOES OSMOSIS AND DIFFUSION NEED ENERGY?
NO
6 of 17
WHY DOES ACTIVE TRANSPORT NEED ENERGY?
THE PARTICLES ARE BEING ABSORBED AGAINST THE CONCENTRATION GRADIENT
7 of 17
WHY IS GLUCOSE USED DURING EXERCISE?
FOR RESPIRATION TO RELEASE ENERGY
8 of 17
WHERE IS OXYGEN ABSORBED IN THE BODY?
THE LUNGS
9 of 17
WHY DO THE LUNGS HAVE A LARGE SURFACE AREA?
TO DIFFUSE AS MUCH OXYGEN AS POSSIBLE
10 of 17
GIVE 3 FACTORS AFFECTING THE RATE OF DIFFUSION
ANY 3 FROM: SURFACE AREA, CONCENTRATION OF GRADIENT, THICKNESS OF MEMBRANE, TEMPERATURE AND SIZE OF PARTICLES
11 of 17
DEFINE DIFFUSION
THE NET MOVEMENT OF PARTICLES FROM AN AREA OF LOW CONCENTRATION TO AN AREA OF LOW CONCENTRATION
12 of 17
GIVE AN EXAMPLE OF DIFFUSION THAT TAKES PLACE IN THE BODY
BREATHING AND IN REFLEX ACTIONS
13 of 17
WHAT IS THE BREATHING SYSTEM DESIGNED TO DO
TO MOVE AIR IN AND OUT OF THE LUNGS
14 of 17
WHEN YOU INHALE, WHAT HAPPENS TO THE PRESSURE AND VOLUME IN THE LUNGS?
VOLUME- INCREASED PRESSURE- DECREASED
15 of 17
WHICH MUSCLES CONTRACT WHEN YOU BREATH?
INTERCOSTAL MUSCLES AND THE DIAPHRAGM
16 of 17
GIVE ONE ADVANTAGE OF A POSITIVE BREATHING AID COMPARED WITH THE IRON LUNG
ANY ONE FROM: SMALLER,THE PERSON DOESN'T HAVE TO LIE IN A METAL CASE, CONTROLLED BY COMPUTERS AND CAN BE USED AT HOME
