1) Calculate the pH for a specific [H+]. Calculate pH given [H+] = 1.4 x 10-5 M
pH = -log10[H+]
pH = -log10(1.4 x 10-5)
pH = 4.85

Mechanisms of evolution
1. Mutation a change in the DNA of a gene. Mutations result from events such as copying errors
during cell division, mechanical damage when molecules and cell structures collide with DNA,
exposure to certain chemicals (ca
Stress is the condition in which an environ-mental change results in a decrease in the rate of an
important physiological process, thereby lowering the potential for an organisms survival,
growth, or reproduction.

The study of life histories is concerned with categorizing variation in life history traits and
analyzing the causes of that variation.

Chapter 10 Questions:
1. One way to synthesize specific DNA segments to insert for recombination is amplifying
the DNA using Polymerase Chain Reaction. The other way would involve the copying of
mRNA to complementary DNA using enzymes for reverse transcri
