A&P 1 Cumulative Final Exam BSC 2085 HCC UPDATED ACTUAL Questions
and CORRECT Answers
, Describe the levels of organization of the human body Chemical level - atoms --> molecules
listed from smallest to largest. Cellular level - organelle/cells (made up of molecules)
Tissue level - group of similar cells
Organ level - made up of different tissue with same goal
Organ system level - different organs that work together
Organismal level - human - made up of made organ systems.
Define anabolism builds molecules, requires energy released from catabolism
Define catabolism breaks down molecules into smaller units that are either oxidized to release
energy, or used in other anabolic reactions.
List 5 characteristics of living things maintain boundaries, movement, responsiveness, digestion, metabolism,
excretion, reproduction, growth
The ability to sense and respond to changes in the responsiveness
environment is a physiological ability called..
electron charge negative
proton charge positive
neutron neutral
Define ion charged particles
Define anion gains electrons - negative charge
Define cation losses electrons - positive charge
a lasting attraction between atoms that enables the Chemical bond
formation of chemical compounds
attractive force between electropositive hydrogen of one Hydrogen bond
molecule and an electronegative atom of another
Hydrogen bonds form (between or within) molecules and between; polar
involve (polar or non polar) molecules
What type of bond involves SHARING of valance shell Covalent; yes
electrons? Is it a strong bond?
What are electrolytes dissolved ions
What is a pH scale measuring how acidic or basic a substance is
Integumentary system involves hair, skin, nails
skeletal system involves bones, joints
