Ecology, Evolution, and Plant/Animal Systems Guided Review
1) Go to the Ecology webpage of my website. If you need Chi square review, click on the Chi
Square tutorial and show your calculations below. What is the point of the Chi square test?
2) Now click on the Fruit Fly Behavior Lab and read S145 to S151. How do you sex fruit flies?
3) What are the 3 types of taxis responses that were studied, and how do the flies respond to each
(positive, negative, or both)?
4) For the chemotaxis part of the lab, what was the procedure?
5) Now find your inquiry lab report that you wrote and read through it. What did your group
study and what were your significant findings?
6) As a class, we discussed why fruit flies were attracted to fermenting/rotting substances. What
are the evolutionary reasons for this behavior?
7) Next, go to the Evolution webpage of my website. Click on the BLAST lab and read through
page S41-S50. What is bioinformatics?
8) What does BLAST stand for?
9) What is BLAST used for?
10) Use Figure 2 to answer the following questions:



Which organisms have lungs?
What three structures do all lizards possess?
According to the cladogram, which structure — dry skin or hair — evolved first?
11) Do the 2 Getting Started questions from S43-S44:
Name________________________________
12) Summarize the procedure of the lab:
13) Go back and look at your lab report. Where did you end up placing the fossil on the
cladogram based on your results and why?
14) What gene did you BLAST for the inquiry portion and what did you find out?
15) Next, go back to the Evolution webpage and click on the Hardy-Weinberg lab. Read
through pages 8-18. What are the 5 conditions of Hardy-Weinberg equilibrium? MEMORIZE
THESE!
16) What do each of the following represent?
 p=
 q=
 p2=
 q2=
 2pq=
17) Which of the above do you have to know to calculate everything else?
18) What are the 2 equations you use to solve any Hardy-Weinberg question?
19) Summarize the procedure for each part of the lab, including what each scenario
represents:
 8A –

8B –

8C –

8D –

8E –
20) Pick a couple of the questions on pg. 18 to redo below, then find your original lab and
check your answers. You may want to also find your Hardy-Weinberg quiz and go over
that.

21) Next, go to the Plant and Animal Systems webpage on my website. Click on the
Transpiration Virtual Lab. Go through the lab until you get to the test yourself page.
Do the 3 questions and check your answers:
1)
2)
3)
22)
How do guard cells function?
23)
What is the equation for photosynthesis?
24) Do the 4 questions on factors that affect the rate of transpiration and check your
answers:
1)
2)
3)
4)
25)
Summarize the design of the experiment, including the different experimental groups:
26)
Why do you have to calculate leaf surface area?
27) Analysis of Results I – Calculate the rate of water loss in ml/m2/min (most righthand
column):
Room –
Light –
Fan –
Mist –
28)
Put the above in order from highest rate of water loss to lowest and explain why:
