Water has many unique properties that make life possible on Earth. One property is cohesion. The cohesion property is properly defined as the binding of water molecules by hydrogen bonds. Water has this property as a result of the chemical bonding between water. Cohesion of the strong hydrogen bonds allows the water molecules to stick together‚ almost as a unit of one. A force exerted on one of the molecules will be exerted on all of the adjacent molecules as a result of cohesion. Cohesion‚ often

“Scientists have recently proposed a reorganization of the phylogenetic system of classification to include the domain‚ a taxonomic category higher than the kingdom category.” A. The three-domain system allows for the conclusion that the previous five kingdoms were more connected than was believed. Out of the five previous kingdoms: Animalia‚ Plantae‚ Protista‚ Fungi‚ and Monera‚ four of the five kingdoms were placed in the same domain- Eukarya. The one remaining kingdom was separated into

FRQ #3 a.) The first property of water is its polarity. A water molecule is formed by one oxygen atom covalently bonded to two hydrogen atoms. The electronegativity of the oxygen atom creates an unequal sharing of electrons between the O and H atoms of the molecule. This also gives water the ability to form hydrogen bonds between the slightly negative oxygen atom and the slightly positive hydrogen atom. Water has a high specific heat due to the hydrogen bonds. Because of this‚ water requires

Adriana Gutierrez AP Biology Lab 9 Analysis 1. For this experiment‚ what were the independent variable and the dependent variable? What were the constants? The independent variable of this experiment are the environmental factors that you are testing on the rate of transpiration‚ so our independent variables would be bright light‚ fan‚ dark‚ and misted. The dependent variable is the rate of transportation because this depends on whatever environmental factor the plant is placed. The constants

1. Kent and Jebreel both ask Danielle out on a date. Kent is very attractive and a lot of fun to be with‚ but he’s also employed. Jebreel is older than Kent‚ has a secure job‚ and owns his own home; however‚ Jebreel is quite unattractive and not very much fun. Daniel chooses to go out with Jebreel instead of Kent.

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical
