Learning Goal #1: I can explain the characteristics of living things (6)

1. Explain two characteristics that help scientists classify organisms as living. ______________________________________________________________________________________________________________________________________________________________________________________

2. You just found a coloured mass in your flower soil. You are trying to decide if it is living. What are three things

that you are going to do to test if it is living? Outline what you are going to do and WHY this would give you information about whether it is living or not. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Learning Goal #2: I can discuss types of viruses and how they attack your body (6)

1. Why are viruses not considered living? Justify with at least three points. ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

2. Draw and label the lytic cycle of a viral infection.

3. Some scientists think that viruses could have been the most ancient organisms and have started the evolution towards living cells. What would evidence that might use for this argument? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

4. Someone could be HIV positive for several decades without having AIDS. Why is that? What is the distinction of that? ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

5. Draw a label an example of a virus.

Learning Goal #3: I can explain the structure and function of DNA (6)

2. Given the following sequence of nucleotides, write the other strand:

Original Strand: 3'- GGTCGCCATCAAGCG-5'

_____________________________________________________________________

3. What are the 3 main parts to a nucleotide?

a. ________________________

b. ________________________

c. ________________________

4. What is this cartoon referring to?

5. Explain what you know about the two processes that happen to create protein. What are they named? Where

do they occur? What is needed for the process?

Process #1: ____________________________ Process #2: ______________________________

6. We had an opportunity with our DNA inquiry to learn from classmates. What were two topics about DNA that

you learned about that interested you. State two facts about interested you and one additional question you still

have about DNA for that topic.

Learning Goal #4: I can explain taxonomy principles (6)

1. Complete the below chart about the Kingdom system

Kingdom Name Type of Cell (prokaryotic or eukaryotic) Example organism (common name)

2. You have just encountered an organism that you have never seen before and you are wondering what Kingdom

and phylum it might be classified as. When you look at the cell structure under the microscope you notice that

it does not have a nucleus. You had found the organism in an area with extremely high concentration of

methane gas. What is the domain and kingdom of the organism? Justify your answer.

Domain: _______________________________

Kingdom: ______________________________

4. Acer circinatum, Acer glabrum and Acer macrophyllum a. all belong to the same species b. would be able to interbreed successfully c. all belong to the same genus d. all belong to a different family

Learning Goal #5: I will explain the unifying characteristics of Kingdom Archae (6)

1. 20 years ago Kingdom Archae and Kingdom Eubacteria were considered the same Kingdom. What has caused

scientists to separate them into separate Kingdoms?

2. You look under the microscope at an archae bacteria. You are under oil immersion and notice that you could

probably fit 20 archae across the oil immersion field of view. How long is the archae bacteria? Objective Lens FOV (µm)

Scanning 4500 µm

Low 1800 µm

High 450 µm

Oil 180 µm

3. What is the respiration method of most archae? What does this mean?

1. What type of bacterial cell has the outer layer as shown below?

2. Draw and label a prokaryotic cell. You may choose the shape. Be sure to include all important structures of the

cell.

3. What are two ways that antibiotics impact bacterial growth?
