1. Think about chemical reactions in your everyday life. How might it help to know about different types of chemical reactions? 2. Consider the equation A + B --> AB. Can you think of another situation you have encountered (outside of this course) where a process in this general form takes place?
3. Describe a chemical reaction that you have recently witnessed. How did you know that it was a chemical reaction? What type of chemical reaction do you think it was?

This is one of the five kingdoms in the older biological succession. organisms in this kingdom are prokaryotic

What is the main difference between the central nervous system (cns) and the peripheral nervous system (pns)? .the cns involves the brain and spinal cord, and the pns involves the body nerves. the cns involves the body nerves, and the pns involves the brain and spinal cord. the cns involves sensory neurons, and the pns involves motor neurons. the cns involves motor neurons, and the pns involves sensory neurons.

Whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
