Next we took notes based on this power point on agents of change....if you weren't here, make sure you watched the linked videos as well.    Homework due Friday:  Read pg. 174-175   and 181-182.  Do Review page 182 #1, 2, 3, 7 and 8. 

Science 10

Today we did a quick question based on punnett squares.  Next we adopted some alien babies with two alien parents.....we had to figure out would their traits would be from a mix of alleles.   Next we did a human variations lab to look at the frequency of alleles for different traits--Turn this in.     Finally we did the following questions in the textbook:  pg. 39 #4, 5 and 10. 

Science 10

More Punnett Square partner practice today.   Also worked on our human karyotypes. 

Biology 11

I collected questions on marsupials from yesterday next we took notes on DNA including DNA base mutations.   We did a worksheet on DNA mutations.   Make sure you turn in the video analysis questions tomorrow. 

Biology 12

Today we did power point notes on the cell membrane and transport across the membrane.   We also looked at osmosis and diffusion.   You should do module questions on the cell membrane, endoplasmic reticulum and ribosomes.   Bring in any materials to build the cell game. 

Biology 12

Today we started our next unit on cells and cell organelles.   We started the big power point notes.   Module questions Section B:  Cell Structures up to iii) the nucleolus is due tomorrow.

SHORT ANSWER:
1.  Draw any two monomers (like two amino acids) link them together by getting rid of an OH from one molecule and an H from the other (dehydration synthesis forms a polymer).  Water is produced in dehydration synthesis.  Hydrolysis splits polymer back into monomers.

2.  Carbohydrates:  sucrose, glycogen, monosaccharide, starch
Lipids:  Steroid, fatty acids, saturated
Proteins: Enzyme, peptide, amino acid, tertiary structure

3.  Denaturing can change the shape of a protein by distruption of the hydrogen bonds that hold the structure together.  Heatings or changing the pH can denature proteins.

4.  Draw ring structure of glucose.  Draw rough sketch of starch (plant energy storage), glycogen (animal energy storage) and cellulose (plant cell walls) as polymers of glucose.
