CHAPT 1 - The scientific method allows the solving of problems and answering of questions. Observations Proposing ideas Testing the ideas Discarding or modifying ideas based on results Hypothesis: proposed explanation for a set of observations Hypotheses needs to be: Testable – it must be possible to examine the hypothesis through observations Falsifiable – it must be able to potentially be proven false Both logical and creative influences are used to develop a hypothesis A hypothesis

SCIENCE CELL – STRUCTURE AND FUNCTIONS Cell – Structure and Functions Cell as the Basic Unit of Life The cell is the basic structural and functional unit of all living organisms. It is the smallest part of the body of an organism‚ is capable of independent existence and is able to perform the essential functions of life. Discovery of the Cell Robert Hooke observed cork cells under a simple microscope designed by him. He observed compartments resembling honeycombs and each compartment

Article Review: Cancer 1. Gibbs‚ W W. "Untangling the Roots of Cancer." Scientific American July 2003: 56-65. Print. 2. In the human body‚ cells are constantly going through the cell cycle. An important step of the cell cycle is called mitosis‚ in which the cell (referred to as the parent cell) undergoes a series of steps that lead to the formation of two daughter cells. This process only occurs in somatic cells‚ which are any non-gamete cells. Gametes are haploid (containing only half of a full

MODULE 2: GENETICS‚ VARIATION AND NATURAL SELECTION SPECIFIC OBJECTIVES & EXPLANATORY NOTES 1. Structure and Roles of Nucleic Acids 1.1 illustrate the structure of RNA and DNA using simple labelled diagrams; The genetic substance found in all organisms called DNA or deoxyribonucleic acid is a kind of nucleic acid. Nucleic acids consist of two long polymers of simpler units‚ called nucleotides; that are composed of three (3) main units as shown below: 1) A pentose sugar (deoxyribose

Chapter 29 An Overview of Land Plant Evolution 1. Describe four shared derived homologies that link charophyceans and land plants. a. The complexes that produce cellulose are rose shaped in both charophyceans and land plants. Next both have peroxisome enzymes that help minimize the loss of organic products from photorespiration. The structure of their flagellated sperm is very similar. Finally‚ both form a phragmoplast during cell division. 2. Distinguish among the kingdoms Plantae‚ Streptophyta

Know definitions of the words used for Meiosis‚ Mendel’s work and Genetics Dominant – expression that is always expressed when its gene recessive - An expression that is expressed only when its allele is the only form of the gene present in the genotype. incomplete dominance - Neither allele is dominant to the other‚ thus each is expressed in the heterozygous genotype producing an intermediate phenotype. EX. Red (RR) and White (R’R’) snapdragons produce pink (RR’). epistasis - A condition

prokaryotic and eukaryotic cell is the nucleus. Eukaryotic cells have a membrane enclosed nucleus‚ while prokaryotic cell does not. Prokaryotic cells reproduce and divides through binary fission‚ while eukaryotic cells reproduce and divides through mitosis and meiosis. However‚ despite the differences‚ both prokaryotic cells and eukaryotic cells contain ribosomes and DNA as their genetic material. Overall‚ prokaryotic cells is much differ than eukaryotic cells‚ as well as the structure of their organelles

the mutation took away fa from fat so the codons all mix and squish together to fill that gap. Duchenne muscular dystrophy is caused by a defective gene that produces dystrophin. it sometimes occurs in people without a family history of Duchenne. Meiosis is a process where a single cell divides twice to make four cells that only have half the original amount of genetic information. These cells are our sex cells; sperm in males‚ eggs in females.
