Experiment 1: Identifying Cell Structures
View the images of cells below, paying attention to detail, and note the different characteristics of
prokaryotes and eukaryotes. For each image, label the parts indicated
1. Define species according to the biological species concept.
The biological species concept defines a species as a group of populations whose members have the
potential to interbreed with one another in nature to produce fertile offspring (offspring tha
1. If someone was trying to lose weight, what would be the "secret" that you would tell them so that
they would succeed?
The secret I would tell them would be to eat less and exercise more.
2. Explain the differences between herbivores, carnivores and omn
1. Define anatomy and physiology.
Anatomy is the study of the structure of an organism's parts. Physiology is the study of the function of
2. What is a tissue? Briefly describe the four main tissues your body is composed of.
A tissue is an in
1. List and briefly describe each stage of the four stage hypothesis for the origin of life.
Stage 1: Abiotic Synthesis of organic Monomers- The abiotic (nonliving) synthesis of small organic
molecules, such as amino acid and nucleotide monomers.
1. Which four elements make up approximately 96% of the weight of the human body?
The four elements that make up approximately 96% of the weight of the human body are oxygen,
hydrogen, nitrogen, and carbon.
2. What is the total number of protons and elect
1. Define Biology
Biology is the scientific study of life.
2. List and give a brief description of the seven properties of life described in Chapter 1.
(a) Order. All living things exhibit complex but ordered organization, like in the structure of a pine
1. Gregor Mendel's work provided the basis for modern genetics (the scientific study of transmission
of traits from one generation to the next). Describe the four ground breaking hypotheses proposed by
Mendel in his 1866 paper on heredity in pea plants.
1. What is parthenogenesis?
Parthenogenesis is the production of offspring by a female without involvement of a male.
Parthenogenesis is one form of asexual reproduction, the creation of a new generation without
participation of sperm and egg.
2. What are
1. Define photosynthesis. What is the function of the thylakoids?
Photosynthesis is a process whereby plants, algae (protists), and certain bacteria transform light energy
into chemical energy, using carbon dioxide and water as starting materials. The thy
1. What percentage of the energy stored in the chemical bonds of gasoline is converted to useful work
in an automobile engine?
Only about 25% of the energy that an automobile engine extracts from its fuel is converted to the kinetic
energy of the car's mo
1. What causes lactose intolerance? Is there a way to treat it?
To absorb this sugar, digestive cells there must produce a molecule called lactase. Lactase is an enzyme, a
protein that helps drive chemical reactions. People with lactose intolerance produc
