Biology Grade 11 Exam Study Guide Diversity Taxonomic Categories Domain Kingdom Phylum Class Order Family Genus Species Hierarchy From most general to most specific Binomial Nomenclature System used to identify all organisms on Earth Identifies an organism by its genus and species (ex. Humans-homo sapiens) Developed by Linnaeus in the 18th century Identifying Species 3 methods: Morphology Form and shape It is simple but there are natural variations in population Biology

Evolution Test Notes Giulia Palazzo • THE HARDY- WEINBERG PRINCIPLE: - a mathematical equation created to predict genotype and phenotype frequencies in a population that is not experiencing any selective pressure‚ if model fails evolution must be occurring - Under Mendel’s model‚ the two alleles can be represented by... p + q = 1 (100% of the alleles in the population) where p is the dominant allele and q is the recessive allele - The genotypes can be represented by the equation (p+q)² = p² + 2pq

Unit1: Cell functions/ Cell division Cells Cell theory: -All living things are composed of one or more cells. -The cell is the smallest entity that retains the properties of life. -New cells arise only from cell that already exists. Structure of the cell: The outer boundary (plasma membrane) similar to a city wall It is constructed with molecules called lipids (fat and oils) The cell membrane is composed of: -Proteins and Lipids -FUNCTION: to allow molecules into and out of the

Varroa mite (infects beehives and sucks of bees’ blood)‚ the Israeli acute paralysis virus (immobilizes and kill bees) No genetic diversity = Less resistant to parasites Biodiversity: variety of life in the world‚ product of millions of years of evolution‚ adaptation Genetic Diversity: sum of all the different forms of genes present in species Species: population whose members can breed freely in nature and produce fertile offspring Hereditary characteristics make an organism unique and ensures

Grade 11 Physics: Summative Cart Analysis Report 2012 – 2013 Purpose: • To build a gravity cart that moves by using the gravitational potential energy from a falling mass. • To record the motions of the cart by and analyze the motions through d-t‚ v-t‚ and a-t graphs. • To find the efficiency of energy and explain the factors those cause the loss in energy. Procedure Building cart 1. The materials for the cart were gathered. - Shoebox (1) - Pole (2) [0.75cm radius] - Axle (2) [0
