BIOL 1107 Lecture Notes - Lecture 1: Protist, Natural Selection, Dependent And Independent Variables
Document Summary
Systems of biology- constructs models of dynamic behavior. Structure and function of living organisms are closely related. Dna is not all genes some have encoded regions (encoded dna is your traits) Advances in systems of biology at cell and molecular lever depend on: The traits of a species change over time. Evolution: populations with may traits, elimination of certain traits, reproduction of survivors. Cell theory : all life is cell based. Four kingdoms in eukaryotic: kingdom plant, kingdom fungi, kingdom animalia, protista. Taxation groups: species, genes, family, order, class, phyla, kingdom, domain. Biosphere- ecosystems- communities- populations- organisms organs organ system tissues cells organelles molecules. Information- dna transfer and expression of genetic information. Interactions and response homeostatic (body temp and sweat) blood sugar insulin. Chapter 1 : themes in the study of life. Fitness: the ability for an animal to produce offspring. Adaptation: trait that enhances fitness in certain environments. Science can be hypothesis based or discovery based.
