Ok, now back to biology.

The biology semester final is worth 10% of your overall grade in biology.  There are no retakes allowed on this test, so we want you to be as prepared as possible before you sit down for the test.

The test is 32 questions long.  26 questions are multiple choice, and 6 are short constructed responses.  It will take you about an hour.  12 of the 32 questions are on the topic of evolution, which we have not yet learned.  These questions will not count towards your grade on the final, but we want you to do your best on these questions anyway.  On the remaining 20 questions, the following topics are covered:

We want you to prepare for the final by completing mini-quizzes for each topic.  The mini-quizzes are all online, and you get a second chance for each one you get wrong.  If you get a question wrong, you will be taken to a "woops" page, where you get to learn a bit more about the topic and then answer the same question again.  Keep track of how many times you answer incorrectly, because this gives you an idea of how well you will do on this topic on the final.

The MINI QUIZZES:

Transport (20%)

Biological Organization, Organ Systems, Organ Function (30%)

Homeostasis, Thermoregulation, Blood Sugar Regulation(30%)

Cell Organelles and Respiration (15%)

Graph Interpretation C-E-R (5%)

Studying

Hi team,

The unit 2 test is on Wednesday, 12/10.  This test is worth 20% of your overall grade in biology.

Here is a study guide I wrote to help prepare and to help you debrief after the test.  Good luck!

Here are some flash card sets on quizlet.  Use these to study your vocab!
Immune System
Thermoregulation
Cell Organelles
Blood Sugar Regulation

Thermoregulation

Hello students!  Today is going to look a little different than our usual classes.  We are learning about how different animals regulate their body temperature through physiological and behavioral mechanisms.  For each example below, examine the resources, decide if the mechanism is behavioral and/or physiological, and explain the response on your table.  If a mechanism does not have resources, skip it for now and come back to it.

Honeybees

Honeybees use their wings to fan the hive on hot days to keep it cool.

Arctic Fish

Trees

Reptile Fins

Leaf Colors

Feathers

Birds puff out their feathers to trap cold air and keep their skin warm underneath.

Basking

Reptiles are cold-blooded, which means that the temperature of their body is the same as the temperature of their surroundings. In order to warm up, reptiles, like this Tiger Snake, bask in a sunny place to gain body heat.

Panting

Burrowing

Animals burrow for many reasons: Living underground allows them to stay away from predators, or to look for food that is unavailable to predators that live above ground. In the hot summer months, animals use their burrows to stay cool. In the cold winter months, animals use their burrows to stay warm and to save energy by hibernating or "napping" instead of looking for food.

"When hummingbirds sleep, they go into a hibernation-like state called Torpor (pronounces TOR-per). This is a really deep sleep. Their metabolism will lower to one-fifteenth (1/15) of normal. Their body temperature will drop to the point of becoming hypothermic. Their heart rate will drop to about 50 beats per minute. Their breathing will slow to the point that it looks like they have stopped breathing. By sleeping like this, hummingbirds can save up to 60% of their available energy."

Mousecapades - Extreme sports for pet mice and hampsters

Mousecapades is currently accepting submissions for designs for bungee cords designed for pet rodents in extreme sports situations.

Preliminary data can be found here.

Problems and questions:

How many rubber bands should be used to safely drop beloved pet rodents a distance of 423 cm?

The preliminary data is based on the use of only 7 rubber bands with drop heights of up to 77 cm.  How will increasing distances of acceleration affect the average rubber band stretch distance?

What systemic errors could potentially result in catastrophic equipment failure?

Practice for the FINAL

Bird Beaks

Hi all,

We have recently been learning about adaptation, the process by which natural selection shapes the traits within a population of organisms to best fit their environment.  Adaptive traits are the features that allow an organism to be fit for its environment (to survive AND reproduce).

Today we are going to examine bird beaks.  Bird beaks are all shaped differently according to what the bird eats.  We can say that the beaks are adaptive - they are shaped by natural selection to allow the bird to eat its food.

Let's look at some different birds feeding:

Biology Quiz 2.4

Hi all,

You have 3 things to accomplish today.

1. Complete your natural selection laboratory assignment.
2. Complete Quiz 2.4 on paper and then enter it online here.
3.  Read this article and answer the discussion questions here.

Have a good weekend :)

Natural Selection Lab Report

Today we are completing another simulation of natural selection, but this time we are going to investigate the variables individually in a laboratory investigation.  Here are the instructions and the worksheet (which you already have).

Click here to get to the simulator.

To run the simulator, you must..

1. Click "Download"

2. Click on "Keep"

3. Click on the file name.

4.  The simulator may give another warning as it opens.  If this is the case, tell it to run!

If you get another odd error, please ask for help.  

If the simulator opens, add a friend:

5.  Familiarize yourself with the variables before you begin the lab:

Natural Selection Labs

Today we are in the computer lab, using various natural selection simulators.  Please complete the worksheet for each of these websites:

Peppered moth - http://www.techapps.net/interactives/pepperMoths.swf

Colored ants - http://www.mhhe.com/biosci/genbio/virtual_labs/BL_12/BL_12.html

After you complete the worksheet, hand it in to Mr. Trainer.

Please take a look at our word wall for this unit here.  Now make a word wall entry for "Adaptation" and email it to me at james_trainer@dpsk12.org.  Your entry needs to include the word, a definition, and an image.  You may use Powerpoint or any other software to help you build the entry.
