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.

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. Identify the features of the oceans' basins and relate the structures observed to theories of origin.

Discuss the co-evolution of the earth and its resident biology. Discuss basic chemical oceanography in terms of the special properties of water and dissolved salts and dissolved gases. Describe the motions of the seas — as currents, waves and tides — in terms of causes and their influences and effects upon the land.

Recognize the adaptations of marine organisms to special properties of the ocean such as light and sound. Identify the features of special animal groups such as sharks, protozoa and marine mammals. Realistically assess the resources of the sea in terms of minerals, energy and food.

Discuss the reasons for and the means by which humankind uses and misuses marine resources. Appraise the nature and power of man's growing interferences with the often subtle interrelationships of the chemistry, physics and biology of earth.

Describe areas of intense scientific interest and public concern such as plate tectonics and earthquake predictions, the impact of ocean pollutants, climate fluctuations, cetacean intelligence, and ocean technology.

Identify the causes of marine pollution and understand the problems of containment and alleviation. Recognize that all parts of the world are interconnected by the sea and that this planet's last frontier needs help in its preservation.

Lab 1 Osmosis -

Define oceanography and list and briefly describe at leave five branches of this science. Discuss science as a way of understanding the universe and accumulating knowledge.

List the steps in the scientific method and compare and contrast the terms, hypothesis, theory and law as they are used in science. Discuss the big bang theory of the origin of the universe including at least two types of evidence that support this theory.

Explain how and when the sun, solar system, Earth and oceans formed. Compare and contrast the early voyages of the Polynesians, Vikings, Greeks and Chinese, especially their motivations, vessels and seafaring skills. Recognize the importance of record-keeping and catography to voyaging, and the historical role of the Library of Alexandria.

List some of the major contributions to early voyaging of Prince Henry, Magellan and Columbus. Recognize the role of Captain James Cook in the history of marine science, and be aware of his three major voyages. Describe the United States Exploring Expedition, its objectives and accomplishments, and its importance in bringing in the United States into the field of oceanography.

Describe the Challenger Expedition and its major contributions in marine science. Chronicle the rise of land-based oceanographic institutions, from the early beginnings in Naples ad Monaco to the major facilities now operating in the United States.

List the disciplines in which marine research is being done today, as it relates to recent advances in data gathering and technology. Making the Pieces Fit A.

Describe the layered structure of Earth and understand how the structure was determined through the study of seismic waves. Explain the concepts of buoyancy and isostatic equilibrium and their relationship to continental drift.

Understand the source of convection and the role it plays in plate tectonics. Compare and contrast the terms continental drift, seafloor spreading and plate tectonics. Explain the evidence, both direct and indirect, for plate tectonic theory.

F 2 (second filial generation). Offspring resulting from interbreeding of the hybrid F 1 generation.. F factor. lab 6: Diffusion Experiment 2: Concentration gradients and membrane permeability We will dialyze a solution of glucose and starch to observe: • The directional movement of glucose and starch.

• The effect of a selectively permeable membrane. In this lab, we will be using an indicator to test for the presence of starch and glucose.

An indicator is a .

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.
