Blood alcohol content (BAC) is a measure of the amount of alcohol that is present the blood.
A heavier person will have a lower blood alcohol level due to a greater amount of water in their body. The more a person weigh, the more water he/she tends to have in his/her body. The water has a diluting effect on the alcohol so the BAC will be lower in comparison with person who is slimmer and has less water in the body.
This activity requires students to drag organs of different body systems into the human body cartoon (Arnold) classifying them according to certain systems (digestive, skeletal, circulatory/respiratory, and nervous).
At the heart of the eukaryotic cell-division cycle are the precise duplication and segregation of chromosomal DNA. These two events take place at distinct points of the cell cycle: DNA is replicated during S phase, and then the replicated DNA strands are accurately partitioned to the two daughter cells during M phase.
