Biology Midterm Exam Review

Graphs

100

What type of graph is best when looking at the variables temperature and time?

Line graph

200

What type of graph for data about favorite pizza toppings.

Bar graph

300

Measuring respiratory rate of runners over time would be best graphed using which type of graph?

Line graph

400

What are the 5 proper components of any graph? (one is optional depending on the graph)

Labeled x axis, Labeled y axis, Title, graphing the data, key (optional) 

500

Performing a breathing rate analysis on ocean sunfish at different water temperatures would be best graphed using which type of graph and why?

Line graph because the two variables for x and y axis are numerical values 

(breathing rate and water temperatures)

Ecology 101

100

What is the importance/purpose of producers in ecosystems? 

Energy in the ecosystem begins with producers, they absorb sunlight and convert it into chemical energy. Producers are the foundation of any ecosystem.

200

• Non-living parts of the environment such as soil, water, and sunlight are considered         
• A. Decomposers                               C. Abiotic
• B. Biotic                                          D. Scavengers

C. Abiotic

300

• Jane Goodall is a famous biologist who devoted years of her life researching a group of chimpanzees in the wild. Her research sought to answer questions pertaining to which level of ecological organization? A.Organism    B.Population  C. Community   D. Ecosystem

B. Population

Diagram and label the correct direction of energy in the ecosystem of a Hawk, Grass, and Rabbit. 

Grass ----> Rabbit ----> Hawk

500

Explain how two different species of birds are limited in population growth by interspecies competition. (Competition between two species)

- The two species compete for the same food and shelter

-Because of the competition, neither species can increase too much over the other.

-Competition may result in adaptive radiation or extinction.

Scientific Method

100

What is the 1st step of the Scientific Method?

Ask a Question

200

If results do NOT align with the hypothesis, what is the next step of the Scientific Method?

Experimental data becomes NEW background research for a new experiment and new hypothesis.

300

If results DO align with the hypothesis, what is the next step of the Scientific Method?

Communicate your results

400

Which of the following is an example of a properly written hypothesis?

1.  “I think that the sky is blue because there is water in it.”
2.  “If I pour this solution on sugar, then the sugar will dissolve.”
3.   “The sugar may or may not dissolve in a solution.”
4.   “The sky is not blue because there is water in it.”

B. "If I pour... then the sugar..."

500

What are the two types of data? AND What is the best type of graph to use with each?

Qualitative - Observational and non-numerical data. Graph with a bar graph!

Quantitative - Numerical data. Graph with a line graph. 

Variables and Labs

100

What is the Independent Variable?

1. The variable used to cause change in the experiment.
2. The variable which responds to change in the experiment.
3. The variable or variables not in the experiment.
4. The variable or variables we remove from the experiment because they negatively impact the results.

A. The variable used to cause change in the experiment.

200

What effect did the lemon juice have on the apple?

1. The apple tastes better.
2. The apple became discolored more quickly.
3. There is no effect,
4. The apple did not discolor or did not discolor as quickly.

D. The apple did not discolor or did not discolor as quickly.

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 at the end of each minute. They continued to measure their respiratory rates for 3 more minutes after the exercising had stopped.     

What is the Independent Variable?

The exercise performed

Lauren wants to know which location in her apartment is best for growing African violets. She has three African violets. She puts one on the balcony, one by the kitchen window, and one on the mantel in the living room. Each plant has the same size pot and the same soil, and Lauren gives each plant the same amount of water.

Write a proper Hypothesis for the lab above!

If an African Violet is placed ________ then it will grow better than the other locations in the apartment.
