Either of the two strands of a replicated chromosome, which are joined at the centromere. When the cell is not dividing, chromatin exists as a mass of very long, thin fibers that are not visible with a light microscope. Chromista In some classification systems, a kingdom consisting of brown algae, golden algae, and diatoms. Each chromosome consists of one very long DNA molecule and associated proteins.

Refer to the instructor's course syllabus for details about any supplies that may be required. Objectives Describe the special nature of the Earth as a "water planet" and recognize its place in the universe. Compare some of the current theories concerning the origin of the planet and the waters that cover its surface.

Experiment involving titrimetric procedures. isoprene and chloroprene-reactivity –1,2 and 1,4 additions in conjugated dienes,-Diels-Alder reaction. Notice that the starch molecules are too large to pass through the pores in the membrane.

The iodine molecules move across the membrane in both directions, but their net movement is from the bag, where their concentration is higher, into the beaker, where their concentration is lower.

Lab 1 Osmosis & Diffusion Osmosis Lab Introduction: Cells have kinetic energy. This causes the molecules of the cell to move around and bump into each other. Diffusion is one result of this molecular movement.
