Catchy Title for Female Secondary Sex Characteristics

Class started off today with some talk about the endocrine reading. Some people said they didn't understand it, but the quiz wasn't bad. Next, we discussed the endocrine system. We didn't do that long. We basically talked about the gland and their hormone secretions. The pituitary gland regulates nine different glands. A very important concept to understand is homeostasis. This is the balance of hormones in the human body. After that, we took notes on female secondary sex characteristics. Last, we started lab 31. There is no hw due when we walk in tomorrow.



Hw:
lab 31, due at end of class tomorrow. annotate
watch online links of menstrual cycle
review pp.992 and 993

Mitosis

Biology was very interesting today, as always. Mrs. Stein started off the class going over web recources we can use for our cancer research paper. We can either go to science resources or the libguides. Next she went over how to cite our bibliography and what to do after a sentence that you took from a resource. You have to use the MLA guidlines. Next we went over the guidlines for the paper. The format can be what ever you feel like is proper. the rubric consists of:

• Cover page 1 pt
• Grammar, Spelling, Format 2 pts
• Analysis of Cancer Risk Graph (in your intro) - Estimation of Cancer Risk (UP 55) 2pts
• Research on One Type of Cancer 7p ts
• Prevention 2 pts
• Conclusion 2 pts
• Visuals 2 pts
• Bibliography 2pts
• Citations and Appropriate use of resources
• Inclusion of "Estimation of Risk Graph" (UP 55) - colored appropriately
• http://www.turnitin.com/ - submission on time (you must still hand in a hard copy)
• Total pts: 25

Next, we watched the mitosis video that Mrs. Stein showed us. It showed all the stages of mitosis. Then, we took notes on Mrs. Stein's mitosis lecture. The notes:

1. Prophase

• 
  
  chromosomes condense
• 
  
  nuclear membrane dissapears
• 
  
  spindle fibers form as centrioles move toward poles

2. Metaphase

• 
  
  chromosomes line up along center
• 
  
  chromosomes attach to spindle fibers at centromeres

3. Anaphase

• 
  
  sister chromatids seperate and move toward poles

4. Telophase

individual chromosomes gather at poles

nuclear membrane reforms

5. cytokenisis

• 
  
  cell pinches in half
• 
  
  two cells form
• 
  
  animal cells - cleavage furrow
• 
  
  plant cells - cell plate

Finally, we did the lab, where we observed and labeled onion root tip mitosis.
