Transcript
The following document is a running list of vocabulary terms for the Carbohydrate, Lipid and Protein unit for Biology. The unit is one of the larger units and contains a lot of vocabulary to keep straight. In order the help the students I have created this study option for home. Key terms will be added as we introduce them in class- I will put the new terms in a new chart to cut down on printing waste, but the same document will be sent home each time. A copy of this document will also be posted on my teacher website located at: http://www.greenwoodsd.org/Page/1009 To use as Flash Cards: 1. Cut only on solid lines. 2. Fold the card on the dotted line and put a small piece of tape on the open end to secure and make the flash card that should show the definition on one side and the vocabulary word on the other. To Use a Matching Activity: 1. Cut the chart apart completely by cutting on all lines. 2. Have your child mix up the cards and try to match the correct definition with the correct vocabulary term. (A second chart can be printed to act as a key) Gene Pool All the genes in a populations Allele Frequency How often a certain allele is present in a population Natural Selection Process where organisms with “favorable traits” or adaptations are selected to survive specific environmental conditions Adaptations Inherited traits that improve an organism’s ability to both survive and reproduce Limiting Factors Restrain the growth of populations “Survival of the fitteSt” Those with traits that enhance survival for a specific environment are considered fit and more likely to survive than those without the desired trait Fitness A measure of an organism’s ability to survive and reproduce Evolution A change in living organisms over time, specifically in the genetic makeup of a subgroup or population of a species Overproduction More offspring can be produced than can survive to maturity Genetic variation Within a population, traits vary (Ex: beak shape, fur color, jaw size, etc) Struggle to survive/adaptation Individuals compete with each other to survive Differential reproduction Organisms with the “best” adaptation are most likely to survive and reproduce Descent with modification Populations begin to differ even if they descended from the same ancestors (finches, peppered moths)
