Distinguish between control and experimental groups - ANSWER-
An experimental group is the group in an experiment that receives
the variable being tested. One variable is tested at a time. The
experimental group is compared to a control group, which does
not receive the test variable.
Distinguish between hypothesis and theory. - ANSWER-A
hypothesis is an attempt to explain phenomena. It is a proposal, a
guess used to understand and/or predict something. A theory is
the result of testing a hypothesis and developing an explanation
that is assumed to be true about something.
Define Anatomy and Physiology - ANSWER-Anatomy is the study
of the structure and relationship between body parts.
Physiology is the study of the function of body parts and the body
as a whole.

Identify the six levels of organization (chemical, tissue, etc.) -
ANSWER-1) Chemical Level
2) Cellular level
3)Tissue level
4)Organ level
5)Organ system level
6) Organismal level
Identify the requirements for life: - ANSWER-1. Reproduction 2.
Response/reaction to environment 3. Metabolism 4. Growth.
Identify survival needs: - ANSWER-survival needs (5): nutrients,
oxygen, water, stable body temperature, and atmospheric
pressure
What is homeostasis? - ANSWER-The tendency of an organism
or a cell to regulate its internal conditions, usually by a system of
feedback controls, so as to stabilize health and functioning,
regardless of the outside changing conditions.
, 3|Page
What are the basic mechanisms of homeostasis? - ANSWER--
Homeostatic control mechanisms have at least three
interdependent components: receptor, control center, and effector.
- The receptor senses environmental stimuli, sending the
information to the control center.
- The control center, generally the brain, signals an effector (e.g.
muscles) to respond to the stimuli.
- Positive feedback enhances or accelerates output created by an
activated stimulus.
- Negative feedback brings a system back to its level of normal
functioning such as adjusting blood pressure, metabolism, and
body temperature.
Anatomical position - ANSWER-Anatomical position is the
description of any region or part of the body in a specific stance.
In the anatomical position, the body is upright, directly facing the
observer, feet flat and directed forward. The upper limbs are at
the body's sides with the palms facing forward.
Define monomer and polymer; identify their relationship. -
ANSWER-Monomer means "one unit," while polymer means
