Document Summary

Explain the five principal steps of the scientific method: formulate a hypothesis, design a study , collect data, analyze data & obtain results, draw connections from results and use them to develop new hypothesis/share findings with others. Distinguish between independent & dependent variables: independent variable the variable the experimenter manipulates and is independent of all other outside variables that might influence the outcome of the experiment, dependent variable the variable the experimenter measures/the outcome and changes in the variable depend on the manipulations the experimenter makes on the independent variable. Define dna, genes & chromosomes: dna genetic material of all organisms that makes up chromosomes; resembles a twisted ladder, with strands of sugar and phosphates connected by rungs made from nucleotide molecules of adenine, thymine, guanine, and cytosine, chromosomes threadlike structures in the nuclei of living cells; contain genes, genes small units of dna that direct the synthesis of proteins and enzymes and result in the expression of inheritable traits.
