Scientific Method and Data Analysis

The graph below shows the effect of temperature on population size of three different species of fish. Which temperature range could support the growth of all three species?

15-20 C

A scientist wanted to determine the toxicity of venom in five species of snake. He collected data on the mortality (or death rate) from each snake species' bites. Which of the following lists the snakes from most deadly to least deadly?

Bushmaster, King cobra, Eastern coral, western diamonback, european viper

A biology student wanted to study the effect of fertilizer on the growth of tomato plants. He placed an equal number of tomato plants into two containers. Each day for one week, Container A received only water, while Container B received a mixture of fertilizer solution. The table below shows the average height of the plants over the course of the experiment. Which of these statements best describes the results shown in the table?

The plants grown with fertilizer solution have a higher average height than the plants grown with only water.

A biology student wanted to determine if there is a relationship between resting heart rate and time spent exercising per week. He gathered information from 12 classmates and constructed the graph below. What is likely to be a resting heart rate for a student who exercises about 3 hours a week?

69 bpm

A biology student wanted to determine if there is a relationship between resting heart rate and body height. She gathered information from 12 classmates and constructed the graph below. Which of the following is true based on the data?

Height and resting heart rate do not have a direct correlation.

The graphs below show the population size of Organism A in a local lake, and the average temperatures of the lake by month. During which month would you expect the Organism A population to be greatest?

July

An ecologist calculated the average yearly rainfall in a local valley. His data is organized into the table below. In which month was rainfall the heaviest?

March

The graph below shows the effect of temperature on population size of three different species of fish. Which species of fish would thrive at a temperature of 40^\circ\text{C}40∘C40, degrees, start text, C, end text?

Species 3

A biology student wanted to determine if there is a relationship between resting heart rate and time spent exercising per week. He gathered information from 12 classmates and constructed the graph below.

Students who exercise more have lower resting heart rates.

A biology student wanted to see if runners from the track team would have a lower respiratory rate than non-runners during exercise. She determined each student's resting respiratory rate. Each student performed the same exercise for a total of 3 minutes, measuring their respiratory rate the end of each minute. They continued to measure their respiratory rates for 3 more minutes after the exercising had stopped. The table below shows the average respiratory rate of these students over time. Which of the following is best supported by the data in the table?

The respiratory rates of the runners returned to the resting rate 3 minutes post-exercise.

Fertilized eggs from the same species of sea turtle were incubated at different temperatures. The hatchling data is shown in the table below. Which of the following is supported by the data?

The sex of sea turtle offspring depends on the incubation temperature.

A biology student wanted to determine if there is a relationship between resting heart rate and body height. She gathered information from 12 classmates and constructed the table below. Which of the following is best supported by the data in the table?

There is no direct correlation between height and resting heart rate.
