Directions: Read each scenario and explain how photosynthesis and plant growth will be affected in each one. Explain in complete sentences using evidence to support your position. Scenario 1: If an area experienced a drought that lasted for months, with lakes and rivers dropping to levels lower than anyone could remember, what would be the effect on photosynthesis of plants in the area?
Scenario 2: If there were a series of volcanic eruptions and the volcanic ash accumulated in Earth’s atmosphere, what might be the effect on photosynthesis?
Scenario 3: If an area experienced several weeks during which the temperature rose every day to 37–38°C (98.6–104°F), what would you predict about the rate of photosynthesis in this area?

Zoe decided to measure the hand length of each of her classmates. first she marked a line across each student's wrist and lined up a ruler from this mark to the top of the middle finger to measure the length. then she recorded the measurements in the table below. marla did this the same way for each classmate, and then zoe used this ruler to measure each straight line and record the data below. this data is invalid. what is the most likely reason why it is invalid? the ruler is marked in centimeters, but zoe recorded data in inches. the range of lengths is too wide, so zoe must have misread the ruler. marla’s complicated measuring procedure was overly confusing. marla could have been inconsistent while drawing outlines of fingers.
