Biology - October 2007

I instinctively always wanted to climb everything starting from the day i was born. By the time i was 2 i was climbing trees as well as most 10 year olds. I was able to climb up a rope over 20 ft high when i was in kindergarten the 2nd one in the history of the school to do it for my age group and its an old school. My arm span is 2 inches above my hieght compared to the average person's who's arm span is typically below their height. I continued to get better at climbing and getting stronger. I could climb up the rope using only my arms easly when i turned 12. Im now 14 and im incredible at climbing. Im the strongest kid in the grade (and not the biggest). I still desire to climb everything. I know im human but is it possible some genes from thousands of years ago that are dormant in most people got released in me?

These are my notes which I had to make myself from my textbook. See, my teacher DOES NOT teach us anything, and if we ask him a question he calls us idiots. Can someone make it simple for me to understand? Test tomorrow by the way.

-The fluid-mosaic model is a description of cell membrane structure in which phospholipids form a bilayer that has a fluid consistency and is studded with protein molecules.
-Lipids do not dissolve in water, thus causing a border around the cell. The edges of the border defines and contains the fluid lipid layer.
-Biochemists and electron microscopists gave researched intently on the subject and they have concluded that the cell membrane all contains a mosaic of different components scattered throughout it.
-For example, numerous protein molecules stud the phospholipid bilayer, and the phospholipid molecules and some of the proteins can drift sideways in the bilayer. This supports the idea that the phospholipid bilayer has a fluid consistency.
