What are the characteristics of life? - Correct Answers
✅Movement (internal or gross); Responsiveness (reaction to
internal or external change); Growth (increase in size without
change in shape); Reproduction (new organisms or new
cells); Respiration (use of oxygen; removal of CO2); Digestion
(breakdown of food); Absorption (movement of substances
through membranes and into fluids); Circulation (movement
within body fluids); Assimilation (changing nutrients into
chemically different forms); Excretion (removal of metabolic
wastes)
Define homeostasis - Correct Answers ✅Body's
maintenance of a stable environment
,APHY 101 Final Exam Q & As (Verified
Answers) 2026 Update
What is a homeostatic mechanism? - Correct Answers
✅the body maintains homeostasis through a number of self-
regulating control systems; examples are regulating body
temperature and pressure sensitive receptors to regulate
body pressure
Define matter - Correct Answers ✅Anything that takes up
space and has mass (weight). It is composed of elements.
Define element - Correct Answers ✅fundamental
substance composed of chemically identical atoms
Define atoms - Correct Answers ✅smallest particle of an
element; basic unit of matter
What is the structure of an atom? - Correct Answers ✅An
atom consists of a nucleus containing protons and neutrons,
with electrons in
orbit around the nucleus.
Atomic nucleus - Correct Answers ✅the nucleus contains
protons and neutrons
Proton - Correct Answers ✅subatomic particle that has a
positive charge

What are covalent bonds? - Correct Answers ✅Covalent
bonds are formed when atoms share electrons to become
stable with filled
outer shells
What are ionic bonds? - Correct Answers ✅2 oppositely
charged atoms form this bond when electrons are transferred
from one atom to another atom
What are hydrogen bonds? - Correct Answers ✅Weak
attraction between positive end of one polar molecule and
negative end of another polar molecule; formed between
water molecules
