“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
