Mitosis -Duplication of the nuclei -Asexual reproduction -Ensures that each cell gets an exact copy of DNA from original zygote -Is used in cell growth and repair (EX: tumor cells growing, white blood cells multiplying, etc.) Is mitosis synonymous to cell division/reproduction? NO! Meiosis -The process by which the chromosome number is reduced by half -Sexual reproduction -Creates variation -Mutations play a very small role in the genetic diversity of cells -Has to HAVE a diploid st...

punctuated equilibriumA model that assumes that evolution occurs in spurts, between which there are long periods of stasis with little evolutionary change. biological definition of speciesa group of organisms that are reproductively isolated from other such groups Locked speciationrecurrent isolation promotes Adaptive radiationis the phenomenon where one species diverges into many by occupying a series of different habitats within a region character displacementthe process by which rel...

Core Concept: -MOST traits are not based on 1 gene. - Cells in specific tissues such as muscle, determine which genes are active and where they are located during development. - The genome of an organism is represented in each cell. - the key to gene function is the information or instructions to produce proteins. - Mutations occur randomly and are sources of variation. Genetics the study of traits and their inheritance Father of genetics Gregor Mendel; discovered the basic rules of gen...

BSC1010L Diffusion What is the solvent in biological solutions such as cytoplasm and blood? - Answerwater Diffusion takes place in: - Answer- a solution A solution is created when: - Answer- two substances are mixed and one is dissolved in the other True or false. Fat is not soluble in water. - Answer- True In a solution, the substance which there is most of is: - Answer- solvent (ex. water) The other substances in the solution are called: - Answer- solutes Solute and solvent combine ...

BSC1010L Cellular Respiration Which of the following is a product of cell respiration? - Answer- water & ATP Cellular respiration: - Answer- oxygen and glucose consumed carbon dioxide, water, and energy (ATP) released O2: - Answer- inhaled CO2 - Answer- exhaled How does cellular respiration make cell energy in the form of ATP? - Answer- when food molecules (Glucose) are used together with oxygen Equation of cell respiration is: - Answer- O2 + C6H12O6 (consumed) --- yields --> CO2 +...

BSC1010L: How Enzymes Work Important to know about enzymes: - Answer- - essential for chemical reactions - never used up - activity is influences by a number of factors An enzyme reduces the energy necessary to start a chemical reaction. This means that the rate of the reaction will _____. - Answer- increase What is true of an enzyme-catalyzed reaction? - Answer- - an enzyme reduces the activation energy - an enzyme speeds up the conversion of substrate to product - enzymes are not us...

These notes include all things eukaryotes: cell walls, organelles and their roles and characteristics, and movement.

These notes go into detail about photosynthesis and the process and all of the components needed to make it happen. They describe the process of light and dark reactions.

These notes go over the general chemistry needed to understand reactions and properties throughout general biology one. They cover polarity, common elements, common reactions, how they are used in metabolism and in the environment , homeostasis, the role of water, etc.
