Diffusion is
the movement of substances from an area of low to high concentration along a concentration gradient

stay the same
not enough information to answer
If a plant cell is placed in an isotonic solution
There is no water movement into or out of the cell
There is a net movement of water into the cell
There is a net movement of water out of the cell
There is no net movement of water into or out of the cell
Active transport
occurs along a concentration gradient and does not require energy
occurs along a concentration gradient and does require energy
occurs against a concentration gradient and does not require energy
occurs against a concentration gradient and does require energy
Facilitated diffusion is different to simple diffusion because
Facilitated uses energy, simple does not
Facilitated requires transport proteins, simple does not
Simple uses energy, facilitated does not
Simple requires transport proteins, facilitated does not
The correct word equation for aerobic cellular respiration is
water + glucose --> oxygen + carbon dioxide + ATP
glucose + carbon dioxide --> water + oxygen + ATP
water + carbon dioxide --> glucose + oxygen + ATP
glucose + oxygen ---> water + carbon dioxide + ATP
Anaerobic respiration in humans
happens all the time
happens when there is insufficient glucose
happens when there is insufficient oxygen
never happens
Anaerobic respiration in plants
produces lactic acid + ATP
produces water + carbon dioxide + ATP
produces ethanol + lactic acid + ATP
produces ethanol + carbon dioxide + ATP
Living organisms need to undergo cellular respiration
when they are hungry
all the time
during daylight
during night
Photosynthesis occurs
all the time
when light is available (daylight)
when light is unavailable (night)
only if oxygen is unavailable
Comparing ATP yield:
Aerobic respiration makes 2 ATP and anaerobic makes 36/38 ATP
Aerobic respiration makes 36/38 ATP and anaerobic makes 2 ATP
Aerobic and anaerobic respiration both make 2 ATP
Name the reactants in photosynthesis
Glucose + Oxygen + Water
Carbon Dioxide + Glucose
Carbon Dioxide + Water + Sunlight
Carbon Dioxide + Water
The correct relationship shown in the following graph is:
When the temperature increases the rate of photosynthesis also increases until reaching an optimal temperature, when it begins to decrease
When the rate of photosynthesis increases, the temperature will increase
When the temperature decreases the rate of photosynthesis increases
There is no relationship between rate of photosynthesis and temperature
What is the definition for homeostasis?
Maintain an unstable internal environment despite changes in external conditions
Maintain a stable external environment despite changes in internal conditions
Maintain a stable internal environment despite changes in external conditions
Keeping internal conditions at the exact same state
What is a behavioural response to body temperature rising above 37 degrees?
Increased sweating
Remove layers (decrease insulation)
Decrease cell metabolism
Decrease surface area (huddle)
Is shivering an autonomic or behavioural response?
Autonomic
Behavioural
What is a behavioural response to a decrease in body temperature?
Add extra layers of clothing (increase insulation)
Increased cell metabolism
Shivering
Remove clothing (reduce insulation)

In the muscles
What organ coordinates the response in blood glucose regulation?
