Mitosis and the Cell Cycle

Genetic continuity is the transmission of the hereditary material through cell division. The Cell Cycle –      cells do not divide continuously –      in cells capable of dividing, the period between cell divisions is called interphase –      cells spend most of their time in interphase because this is the phase where they perform their functions (obtaining…

Laws of Chemical Change

Observations of chemical reactions are summarized in certain generalizations called the laws of chemical change.  The three laws of chemical change are; 1)  Law of Conservation of Mass 2)  Law of Constant Composition 3)  Law of Multiple Proportions Law of Conservation of Mass States that during a chemical reaction, matter is neither created or destroyed…

ENTROPY

Entropy, S, is the tendency towards randomness or disorder in a system – an ordered arrangement of particles has a lower entropy/disorder than the same number of particles in random arrangements Entropy becomes more disordered with: 1.) ^ Temperature – more chaotic motion 2.) ^ Volume of gases 3.) change in phys. State A change…

Lab Safety Rules

The laboratory is a safe place to experiment if you are careful and familiar with all the equipment. You must assume responsibility for the safety of yourself and your neighbours. This paper outlines the steps to use for safety and first aid in this classroom. Student bags or back packs and coats are not permitted…
