A substance that, in its edible form, is sour to the taste, and in non-edible forms, is often capable of
dissolving metals. Acids and bases react to form salts and water. These are all phenomenological
definitions, however, in contrast to the three
Simply put, a genetic mutation comes from a change in the DNA; this change can result from an
extrachromosomal element, an alteration of the inherited nucleotide (Timberlake, 2014). The basic
building block of nucleic acids, such as DNA and RNA (Timberlak
Discussion question 1:
What do you think is the difference between a theory and a hypothesis? What is the difference between
hypothesis and law? Is there a sequential move from one to another, amongst law, theory, and a
hypothesis? Describe controlled con
PROBLEM SOLVING SKILLS

Cellular respiration is the process of oxidizing food molecules, like glucose, to carbon dioxide and water.
The energy released is trapped in the form of ATP for use by all the energy consuming activities of the
The process occurs in two phases:
Biochemical reactions are chemical reactions that naturally occur in living organisms (Houghton, n.d.).
They involve different biomolecules interacting with each other to create new biochemical for a specific
use in the body (Houghton, n.d.). The major cl

Our understanding of genetic inheritance and the function of DNA in producing the characteristics of the
individual have been developing for more than 150 years. Consider our current state of knowledge. Link

Periodic Table of the Elements
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar
group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G),
and cytosine (C). The order of these bases is what d
This seems like a rather simple question, but think about it for a minute. What do all living things have in
common? What are the common properties? One thing we want to make very clear at this point is
that living means that an entity exhibits all of the
