The Test Review Post

To prevent me from taking too much front-page space, I have condensed the review post into two categories:

Vocab: Click Here (Takes you to a Google Docs page)

Notes (Expanded definitions, etc): Click Here

There's not much here, because most of what you need to know is on the Objectives page (p1)

The test is 17 Friday December 2010.

Good luck.

Homework:

UP 73, 74 and 79 Due Tuesday

Test Friday

Quiz Retakes by Thursday

QUIZ RETAKES

If you got less than 80% on the first 15 questions on the quiz (Less than 12/15), you are eligible for a retake. See Ms. Stein for the required forms and directions.

MORE INFO ABOUT UP 73/4/9.
Due to many people in Periods 2/3 not understanding the questions / reading, this is due on TUESDAY.

GENETIC ENGINEERING

The practice of manipulating genes in DNA for practical purposes

Some common uses include:

Preventing bugs from attacking some types of plants

Slow bruising of apples and pears

BENEFITS OF GENETIC ENGINEERING

Genetic engineering can prevent use of some popular hormones that are used to fatten up pigs, and produce more milk in cows. Due to the inherent risk of using such hormones, genetic modification seems to be the simplest and the healthiest option.

ISSUES WITH GENETIC ENGINEERING

In some cases, genes from completely unrelated species are introduced to others. For example,a common gene in Arctic fish is used to prevent freezing in some tomatoes. This gene is widely used, and has not caused any major problems to date, but it has been blamed for possibly raising the risk of some diseases.

In-Depth Look:
First, we went over the last post, and then we started Lab #58 in our Biology Book. We went to the side of the building to count weeds. We created a 1 meter square with some string, tounge depressors, and metersticks. After, we drew a small plot map, counting dandelion plants, plantains, and clovers. We then divided it into 10 sections, and counted up the amounts for the three different types of plants. When we shared the class data, we all figured out that most of us majorly screwed up counting the clovers in bunches, instead of each individual clover plant (Now that would have taken FOREVER). Then, for homework we were assigned the analysis questions.
