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%)



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!

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."
