Interpreting biological graphs

What does the trend in this graph about photosynthesis show?

• As the light intensity increases, so does the rate of photosynthesis - a positive correlation

• There is no correlation

• As the rate of photosynthesis increases, this leads to an increase in light intensity

• At first as the light intensity increases, so does the rate of photosynthesis, but after the optimum light intensity no further increase in the rate of photosynthesis is seen

Which race has the highest rate of death per 100,000 due to heart disease?

• White

• Hispanic

• American African

• American Indian

What does this graph show?

• That the rate of photosynthesis is highest when levels of carbon dioxide and light are both low

• That the rate of photosynthesis is highest when levels of carbon dioxide and light are both high

• That the rate of photosynthesis is highest when levels of carbon dioxide are high and light levels are low

• That the rate of photosynthesis is highest when levels of carbon dioxide are low and light levels are high

What trends do we see in this graph?

• That the highest level of energy is supplied in the first minute of running at full speed for both aerobic and anaerobic respiration

• That the highest level of energy is supplied in the first minute of running at full speed for anaerobic respiration but not aerobic respiration

• That the highest level of energy is supplied in the first minute of running at full speed for aerobic respiration but not anaerobic respiration

• That the highest level of energy is not supplied in the first minute of running at full speed for either anaerobic respiration or aerobic respiration

What correlation is shown in this graph?

• Humans have increased the rate of extinction

• Both human population and number of extinctions increased rapidly after 1950

• Extinctions increased after the industrial revolution

• There is a link between the rise in human population and the number of extinctions

What is the cause of the shape of this graph?

• The molecules collide more as the temperature increases

• The rate of reactions increases slowly with the initial increase in temperature and then decreases after the optimum temperature is reached

• There is a positive correlation between temperature and rate of reaction

• Above the optimum temperature, enzymes in any reaction will denature and this will reduce and then stop the rate of reaction

If the blue line shows the percentage of people immunised against polio, what overall trend do the blue bars show?

• That the number of cases of polio worldwide dropped between 1981 and 2019

• That the number of cases of polio worldwide kept rising and falling between 1981 and 2019

• That the WHO estimates are in line with the number of vaccinations

• The polio cases have been consistently low since 2000

Which of these is NOT a true statement about this graph?

• The person's resting heart rate was 60bpm

• The exercise period was 10 minutes

• The heart rate rose rapidly when exercise started

• The recovery rate was about 20 minutes

What is the explanation for the trends seen in this graph?

• The more rabbits there are, the less likely they are to be caught so their numbers keep increasing

• When prey levels are high, there is more food for the predators so more of those survive so their numbers increase, so they catch more prey so their numbers go down

• The fox numbers are decreasing as they are being hunted more

• It is the natural cycle of life

Tick ALL the boxes that are true about this graph

• The rate of respiration and photosynthesis and respiration are the same at about 9am and 7pm

• The rate of photosynthesis reaches its peak between about 2pm and 4pm

• Respiration happens continuously throughout the day

• Photosynthesis is at its lowest between 10pm and 10am
