Shannon Yeh October 28‚ 2013 Animal Dentition Laboratory Assignment (Figure 1.) Tooth Sharpness (degrees) (Figure 2.) Relative Tooth Width (mm.) Results: The dental formula is a convention used by mammalogists to determine the tooth number and tooth arrangements. The dental formula is calculated by counting the number of incisors‚ canines‚ premolars‚ and molars present in the upper jaw (one side) and counting the number of incisors‚ canines‚ premolars‚ and molars

Adaptation Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Definition: Adaptation is the process of how organisms develop special structures and internal processes to enable them to live in their environment. Organisms can be adapted in two ways: 1. Body structure (e.g. Small ears to reduce heat loss) 2. Body processes (e.g. Osmoregulation in salmon) There are several factors which

There is a 25% chance that Allison and Tim will have a baby boy who is heterozygous for Tay-Sachs. b. No‚ the baby boy will not have Tay-Sachs he will be a carrier for the disease. The boy would only have the disease if he was homozygous recessive. | X | Y | X | XX | XY | X | XX | XY | 1:2 1:2 | T | t | T | TT | Tt | t | Tt | tt

AP ESSAY ANSWERS: 16-20 1. Information transfer is fundamental to all living organisms. For TWO of the following examples‚ explain in detail‚ how the transfer of information is accomplished. A) The genetic material in one eukaryotic cell is copied and distributed to two identical daughter cells. B) A gene in a eukaryotic cell is transcribed and translated to produce a protein. C) The genetic material from one bacterial cell enters another via transformation‚ transduction or conjugation

Diffusion of Cell Size 2012 Kayla Szabo Loxton High School 2/20/2012 Rate of Diffusion Practical report Introduction: Diffusion is the movement of a substance from an area of high concentration to an area of low concentration. Cells need to utilise diffusion to exchange materials from outside of the cell to the inside of the cell for them to survive. Diffusion is a passive process‚ which means it doesn’t involve the need of energy. For a cell to survive it relies greatly on its size
