How can I tell if a reaction is an acid-base reaction?

You can tell if a reaction is a acid-base reaction if you see an exchange of hyrdogens. For example, if both reactants (left side) either gained or lost an electron on the products (right side) To identify the conjugate base versus conjugate acid: If the product gained an electron, it is a conjugate acid, and if the product lost an electron, it is a conjugate base. You need a conjugate base and conjugate acid to have an acid-base reaction.

What are the different phases of the cell cycle, and what is apoptosis versus necrosis?

In order for cells to proliferate (which means, cells growing and multiplying), the cell must complete the cell cycle. The cell cycle consists of 4 basic phases: 1- G1 phase: the cell grows and produces nutrients and enzymes for the phases later on 2- S phase: DNA replication occurs (cell starts with 2n, or 2 sets of chromosomes, and replicates until 4n) 3- G2 phase: cells complete their growth 4- M phase: this is when the cell divides into 2 daughter cells (the DNA is divided in half and pulled to opposite sides of the cells, and then the 1 parent cell cleaves and divides in half) To be more specific... Interphase, prophase, metaphase, anapahase, telephsae + cytokinesis Apoptosis is programmed cell death, or cell suicide. Necrosis is different, this is when a cell dies due to injury. Apoptosis plays a healthy and protective role in our body!

When would you use affect versus effect?

Affect is used as a verb. For example, "will our training affect how well we play?" Effect is used as an noun. For example, "what is THE effect of temperature on cell growth?"
