STUDY STUDY STUDY!!

Today we started class by turning in our homework, which was the postcard to Grandma Gertrude and UP 32 and UP 37-42, and to read 35.4 by tomorrow. After we finished the tree map on the Immune System, the acquired immunity branch.

In acquired imunity, you should know that it can either be active or passive. Active immunity means that the body makes the antibodies. An example of active immunity is vaccines or exposure to the disease, and active immunity lasts for a long time. Passive immunity means that the antibodies are obtained passively. An example would be breast milk or injections of antibodies. This is more temporary than active immunity.

After, we got the chance to ask Mrs. Stein questions because, we have a test tomorrow!! STUDY HARD EVERYONE!! It's going to be difficult considering there's a lot of difficult material covered in the test. Remember to go over the objectives page in the first page of your yellow UP packet.

The test covers pretty much all of chapter 35 and chapter 20.
