Conclusion - Reject or accept the hypothesis G. Hypothesis must be testable B.
Sample size must be sufficiently large C. Experiment must have proper controls D. Experiment must be reproducible 3 Life is organized at different levels.
Important inorganic substances - water, minerals, salts Important organic substances - carbohydrates, proteins, lipids, nucleic acids ex. They may be unicellular, colonial, or multicellular; and they may be prokaryotic or eukaryotic cells. Biochemical processes are essential to life on earth.
Each atom, in turn, is composed of a certain number of sub-atomic particles: This explains why the atomic weight values often include fractions.
This can be accomplished by gaining, losing, or sharing electrons. These opposite forces of attraction hold the sodium and chloride ions together in the ionic compound sodium chloride.
It may form either covalent or ionic compounds. The electrons are held closer to one of the atoms in the compound than the other which results in partially positive and negative charges existing around the molecule. These hydrogen bonds contribute to most of the unique properties of the water molecule: Properties of Water 1.
Water molecules are cohesive. They are attracted to other water molecules. This contributes to water's high surface tension. Water molecules are adhesive.
They are attracted to other charged substances. Water has a high specific heat. It takes a great deal of energy to heat or cool water. Water has a high heat of vaporization. Water is therefore an excellent evaporative coolant.
Water is more dense as a liquid than as a solid. It reaches its greatest density at 4oC. Water is an excellent solvent. Acids and Bases acid - a substance that donates hydrogen ions in a chemical reaction ex. The pH scale runs from 0 to Study University of Tennessee - Knoxville Biology flashcards and notes.

iridis-photo-restoration.com makes it easy to get the grade you want!/5(1). Welcome to BIO Introduction to Molecular and Cellular Biology. This course is intended for the student interested in understanding and appreciating common biological topics in the study of the smallest units within biology: molecules and cells.
Molecular and cellular biology is a dynamic field. EVOLUTION *Evolution - the changes that have transformed life on earth from its earliest beginnings to the diversity that exists today. Evolutionary biology provides a cohesiveness to nature and allows us to "make sense" of the world that surrounds us.
*Natural Selection - the theory proposed by Charles Darwin to explain the process of evolution. The Biology CLEP study guide TEACHES you what you need to know to pass the CLEP test. This study guide is more than just pages of sample test questions.
