9/23/2011 Continued...

As I mentioned today in class, you are going to have a test next Friday on 1. The Characteristics of Life 2. Bacteria and 3. Viruses. I will post a study guide Monday but it's always a good time for review! Here is a list of some of the more difficult vocab words from the bacterial unit you should be comfortable with. If you don't know what they mean, I highly recommend making flash cards and starting to study them this weekend!

Cilia

Flagella

Prokaryote

Eukaryote

Photoautotroph

Chemoautotroph

Homework:

Do bacteria wrap-up questions. I will paste them all here so there's no confusion. Please answer with complete answers, answering all parts of questions. Original questions are on p. 493-494 (dragonfly book).

11.	What are two distinguishing characteristics of prokaryotes?

12.	Describe the three main cell shapes of prokaryotes.

13.	How do scientists distinguish between Gram-positive and Gram-negative bacteria?

14.	Describe two methods by which prokaryotes move.

15.	How are photoautotrophs similar to chemoautotrophs? How are they different?

16.

State one way in which photoheterotrophs are similar to chemoheterotrophs. 19. What is the role of certain bacteria in changing atmospheric nitrogen into a form usable by plants? 26. Predicting Suppose that bacteria lost the ability to fix nitrogen. How would this affect other organisms? 28. Applying Concepts Why don't foods such as uncooked rice and raisins spoil? 29. Problem Solving Bacteria that live on teeth produce an acid that causes decay. Why do people who do not brush their teeth regularly tend to have more cavities than those who do? 30. Classifying A scientist finds a new organism but is unsure to which kingdom it belongs. The organism is unicellular, has a cell wall containing peptidoglycan, has a circular DNA molecule and ribosomes, but it lacks a nucleus. Based on those characteristics, to which kingdom does it belong? Questions 31–32 An experiment was conducted to determine the effectiveness of different antibiotics against a certain strain of bacteria. Four disks, each soaked in a different antibiotic, were placed in a petri dish where the bacteria were growing. The results are summarized below. 31. Analyzing Data Which antibiotics were the least effective at retarding the growth of the bacteria? Explain your answer using data from the experiment.

Reading Homework: Read p. 471-475 (basically all of section 19-1 that you have not yet read). It should all reinforce what we learned/took notes on today in class. Have your notes out as you read and compare notes to reading to help you remember the info!

Written Homework: On the drawing of a bacterium that you did in class, give each of the parts you labeled a definition on the other side of the drawing. (cell wall, cell membrane, ribosome, pili, flagellum, DNA, peptidoglycan). You can use our book for definitions, not all are boldfaced but all of the info is in your reading!

9/21/2011

Finally...a night with no written homework! But you can always review what we've studied and read so far about Bacteria (section 19-1 in text) if you want to be extra-prepared :-)

9/20/2011

Tonight you are reading the last part of section 19-1 entitled "The Importance of Bacteria" (includes subsections Decomposers, Nitrogen Fixers, Human Uses). Please take notes on this section in your notebook for class tomorrow. Notes can be in any form...2 column, outline...something organized please! Thanks

9/19/2011

Living things can fall into one of these 5 categories, as we discussed today in class:

1. Alive

2. Alive but dormant

3. Dead but once alive

4. product of a living thing

5. Never alive

For tonights homework, take a blank piece of paper and write down each category with a few blank lines below it. Then go into your kitchen. Choose an item that you think fits into each category. Under the correct category, write the name of the item and give at least a 1-sentence explanation of why it belongs in that category.

Have fun!

9/16/2011

Due Monday:

Read Section 1-3 in your textbook entitled "Characteristics of Living Things".

Take notes, making sure you 1) List the 8 characteristics of living things and 2) give some detail--1-2 sentences each-- about each characteristic from your reading.

Have a nice weekend! Good luck to the NAHS football team @home tonight vs. Reading!

9/15/2011

Test Tomorrow!

Be sure to study! If you want your 10 bonus points, make a study guide from the one I posted Wed online and remember to pass it in tomorrow.

*Remember, each time you have a test, binders get checked!*

TONIGHT'S HOMEWORK:

Here's the link for microscope practice:

http://www.udel.edu/biology/ketcham/microscope/scope.html and follow directions.

TO PASS IN TO MRS. KIPP: In your notebook (name and date please!) write down each step as you do it, in the format of a numbered list. For example, it can start with "turn on virtual light".

ALSO you will have a Unit 1 Test Friday of this week. Topics on test include:

-the scientific method

-dependent/independent variables

-what is science

-lab safety

-microscope parts and use

-graphic and metric system
