Organisims interact with their enviroment, exchanging matter and energy.
The potential energy of chemical bonds
The main source of energy for producers in an ecosystem is
light energy
Which of the following types of cell utilize deoxyribonucleic acid as their genetic material but do not have their DNA encased within the nuclear envelope
Archaea
To understand the chemical basis of inheritance, we must understand the molecular structure of DNA. This is an example of the application of which concept to the study of biology?
reductionism
) Once labor begins in childbirth, contractions increase in intensity and frequency until delivery. The increasing labor contractions of childbirth are an example of which type of regulation?
Positive feedback
When the body's blood glucose level rises, the pancreas secretes insulin and, as a result, the blood glucose level declines. When the blood glucose level is low, the pancreas secretes glucagon and, as a result, the blood glucose level rises. Such regulation of the blood glucose level is the result of
Negative feedback

Taxonomy
Prokaryotic and eukaryotic cells generally have which of the following features in common?
Ribisomes
Prokaryotes are classified as belonging to two different domains. What are the domains?
Bacteria and Archaea

What is the major distinguishing characteristic of fungi?
absorbing dissolved nutrients
What are archaea?

a prediction
The application of scientific knowledge for some specific purpose is known as
Technology
Which of the following are qualities of any good scientific hypothesis?
I. It is testable.
II. It is falsifiable.
III. It produces quantitative data.
IV. It produces results that can be replicated.
I and II
When a hypothesis cannot be written in an "If…then" format, what does this mean?
It dosent represent deductive reasoning
Which of the following is the best description of a control for an experiment?
The control group is matched with the experimental group except for the one experimental variable.
Which of these is an example of inductive reasoning?
Hundreds of individuals of a species have been observed and all are photosynthetic; therefore, the species is photosynthetic.
The students plan to gather data from the project. Which of the following would be the best way to present what they gather from experimental groups as opposed to controls?
measuring the number of new colonies formed during every 12-hour period
Systems biology is mainly an attempt to
understand the behavior of entire biological systems.
Which of the following statements best distinguishes hypotheses from theories in science?
Hypotheses usually are relatively narrow in scope; theories have broad explanatory power.
