9/30 Biology Update and homework due 10/7

Hi folks,

Today we took a general outline view of the four biological molecules. We looked at some examples, their basic purposes and different subcategories for each molecule. Next week we will get into more of the details of each molecule.

Now, by the way, is a great time to begin your flash card collection. Draw each monomer and functional group on one side and the name of it on the other. Also, put the vocabulary words on your flash cards to study them as well.


Homework for this week is to:
Read pp. 51 - 61
Do questions 1-7 on pg. 54
Do questions 1-7 on pg. 60

9/16 Biology update and homework due 9/23

Hi folks,

Today we did a whirlwind tour of basic chemistry in order to get everyone ready for the upcoming "Basic Molecules of Biology" block of class.  Here's the link to my favorite (yes, I'm geeky enough to have a favorite) periodic table website.

Homework:

Read the book pgs. 31- 34

Do Section I Review on pg. 34 #'s 1-6 and 8.

Answer the following questions:

(I've included the answers below so that you can check your work.  Be sure you understand these, quizzes are coming.)

1. Draw the probable number of  bonds for the following elements:

a.  O      b.   C      c.  I       d.  Tl      e. Al      f.  Mg

2.  Draw the following molecules (use as many atoms as you need to make the bonds)

a. Li & Br

b. Mg & Te

c. K & P

d. O & O

e. N & N

f. C & O

g. C & H

h. C & O & H

Answers (no peeking until your done!)

1. Hard to draw with email so I'll just give #.  a.  2  b.  4  c.  1  d. 3.  e. 3    f.  2

2. a.  Li-Br

b. Mg=Te

c. P with 3 K's around it

d. O=O

e. N triple bond N

f. O=C=O

g. Many ways but the simplest is C with 4 H's around it

h.  Many ways but one is C=O and put 2 more H's around the C
