For me and many other science geeks and pre-med overachievers, this moment was the first exam in Bio This guide aims to give new first-year bio students a heads-up, to be prepared for the rigor of Bio so that they can get excited about the study of biology. It includes studying tips from past students and comments about what they wish they knew before that first bio exam.
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.Study Flashcards On Biology Final Review at leslutinsduphoenix.com Quickly memorize the terms, phrases and much more.
