Define 'energy'. - -The capacity to do work (to cause change) Compare potential energy and kinetic energy. Classify different energy forms into one of these two categories. - Potential Energy = stored energy 1. Chemical Energy: E stored in bonds of atoms and molecules 2. Concentration Gradient: concentration differences across membrane 3. Gravitational Energy: E of position or place 4. Stored Mechanical Energy: E stored in objects by application of a force Energy Energy = motion 1. Ele...

Sardinilla ProjectA project under Dr. Potvin in Panama. Planted many native trees. Looks for relationship between the number of biodiversity and ecosystem productivity and stability. EcologyThe study of distribution and abundance of living organisms. Ecology seeks to discover the rules of assembly from individuals to ecosystems of biotic and abiotic factors. Ecology is a field science. Means "the house" in greek.

What is Ecology- Study of abundance and production or organisms - How organisms interact with each other, other species and environment What is a Population- Group of organisms of the same species occupying a space - Share a common gene pool -Sexually reproducing populations Population Boundaries- Sets population limits - Can vary in time or space Unitary Individuals- Consist of one module EX: human, deer

Describe the work of Fred Griffith - studied 2 strains of strep 1) S strain- appeared smooth and was virulent 2) R strain- 'rough' in appearance and avirulent - There are several variants of the strains (IIS,IIIS,IIR,IIIR) - IIS can mutate to IIR, but never to IIIR, IIIS mutated to IIIR but never IIR. -When type R injected in mice it survives -When type S injected into mice it dies - However when heat killed IIIS and IIR injected into mice they died and IIIS was recovered -Conclusion ...

explain the rule of phosphoglucomutase in glucose catabolism - it can transform G1P -> G6P during energy investment phase of glycolysis. It can also turn G6P -> G1P to begin the glycogenesis pathway glucose catabolism - if energy needs are met in the cell, G6P is converted to G1P catalyzed by phosphoglucomutase which triggers glycogenesis glycogenesis - the pathway that synthesizes glycogen as a result of excess glucose glycolysis - pathway that turns glucose to pyruvate for use in c...

Two sources of variability that arises during meiosis and fertilizations - 1. Crossing over 2. Independent Assortment Crossing Over - homologous chromosomes pair... each sister chromatid consists of a single stranded DNA molecule What is the result of the crossing over between homologous chromatids? - The exchange of segments Where do the homologous chromosomes separate? - First meiotic division What is produced after meiosis II - two daughter chromosomes have parental combinations of al...
