- Greenhouse Effect Notes
Bio II:
- finish IAs
- check PSOW form
- HL= watch 2 videos from www.khanacademy.org and take notes:
Video 1: Anatomy of a Muscle Cell - http://www.khanacademy.org/video/anatomy-of-a-muscle-cell?playlist=Biology
1) Types of muscle mentioned and differences between them
2) Tendon's function
3) Role of connective tissue
4) Other types of tissue present in a muscle
5) Description of a myofiber (parts, what it looks lile)
6) Why are they multinucleated?
7) What is the sarcolema?
8) Myofibrils are made of?
9) Sarcomere's description
10) A Band and I Band correspond to what?
11) Role of the nerve impulse in contraction.
Video 2: Myosin and Actin - http://www.khanacademy.org/video/myosin-and-actin?playlist=Biology
You need to be able to explain the muscle contraction in steps (talk about the role of ATP, calcium, the change in the protein's shape, proteins involved, consequences to the size of each sarcomere).
