Distinguish between a predator and a prey species and give an example of each. What is a predatorprey relationship? Explain why we should help to preserve kelp forests. Describe three ways in which prey species can avoid their predators and three ways in which predators can increase their chances of feeding on their prey.
Inheritance and Variation Scientific theory: idea with broad general power Scientific law: specific description of a phenomenon - Approximately 50% of genes are received from mother - Expression of a trait is dependent on the trait and genes - Control of gene expressed by the environment would make hard to interpret crosses like Mendel - Theory of blending inheritance: blend of mother and father genes Blending of both genes -blend like black and white paint to make grey - eventually species look the same Gregor Mendel Medel showed that each parent has two units. Each pass one to - Used pure bred pea plants that self pollinate - Pure bred means family line shows that same trait he was observing (in this case color) - Parental generation passes gene down to first generation (F1) - Genes are known as alleles - Two copies of the same gene is known as homozygous - The law of segregation : individuals have two alleles and only one gets passed - Locus: location on chromosome where gene is found - Law of independent assortment and law of segregation are independent from each other - Location of locus on one chromosome does not affect location of lo
