Evolution a heritable change in a population of organisms from one generation to the next. What is the scientific method? A series of steps to test the validity of a hypothesis. This approach often involves a comparison between control and experimental groups. What are the steps of the scientific ...

Autosomes Any chromosome that is not a sex chromosome Sex Chromosomes One of the 23 pairs of chromosomes in the human, contains genes that will determine the sex of the individual. Ploidy number of sets of chromosomes in a cell Diploid 2 sets of chromosomes Haploid (genetics) an organism or cell...

Phospholipid bilayer the basic framework of a biological membrane, consisting of two layers of phospholipids. Fluid mosaic model the accepted model of a biological membrane; its basic framework is the semifluid phospholipid bilayer with a mosaic of proteins. Carbohydrates may be attached to the lip...

cellular respiration A process by which living cells obtain energy form organic molecules in the presence of oxygen and release waste products. aerobic respiration A type of cellular respiration in which O2 is consumed and CO2 is released. Glycolysis A metabolic pathway that breaks down glucose to...

Describe the fluid-mosaic model of membrane structure. The framework of the membrane is the phospholipid bilayer, which consists of two layers of phospholipids. Also includes proteins and carbohydrates. Identify the three different types of membrane proteins. 1. Transmembrane Protein 2. Lipid-Ancho...

Describe the chemical composition of biological membranes? Biological membranes are bilayers of phospholipids with associated proteins and carbohydrates. What can never be energetically favorable in a biological membrane and therefore will not occur spontaneously? the flip-flop of phospholipids to ...

Which macromolecule forms the foundation for the structure and activities of living cells? protein Reducing Atmosphere Hypothesis hypothesis regarding the origin of life on Earth suggests that oxidation-reduction (redox) reactions may be responsible for the formation of complex organic molecules fr...

The human blood type AB in which both the A antigen and the B antigen are found embedded in the blood cells is an example of Codominance An X-linked gene is a gene on the X chromosome A man and a woman are both heterozygous carriers for the recessive allele that causes cystic fibrosis. What is the...

What kind of cell does Meiosis produce? Daughter cells that are not genetically identical to each other or the parent cell (gamete cells) Cytogenics A field of genetics involving microscopic examination of chromosomes and cell division When are chromosomes visible? During cell division b/c they be...
