100 QUESTIONS WITH VERIFIED DETAILED
ANSWERS | ALREADY GRADED A+
Smallest structural level - --ANSWER --Chemical
2nd structural level - --ANSWER --cellular
3rd structural level - --ANSWER --tissue
4th structural level - --ANSWER --organ
5th structural level - --ANSWER --Organ systems
Negative feedback loop - --ANSWER --acts to minimize change and response is to
oppose or negate action of original stimulus
Positive feedback loop - --ANSWER --response exaggerates or enhances original
change
Midsagittal Plane - --ANSWER --divides the body or organ into right and left halves
,Coronal plane - --ANSWER --Divides the body into anterior and posterior parts
Transverse Plane - --ANSWER --divides the body into superior and inferior parts
Parietal pleura - --ANSWER --Lines the thoracic cavity
Visceral pleura - --ANSWER --Covers the lungs
Parietal pericardium - --ANSWER --Lines the pericardial cavity
Visceral pericardium - --ANSWER --Covers the heart
Parietal peritoneum - --ANSWER --Lines the abdominal cavity
Visceral peritoneum - --ANSWER --Covers the abdominal organs
Protons - --ANSWER --positive electrical charge
Neutrons - --ANSWER --neutral charge
Electrons - --ANSWER --negative charge
,Atomic number - --ANSWER --number of protons
Mass number - --ANSWER --protons plus neutrons
Element - --ANSWER --cannot be broken down by physical means
Isotopes - --ANSWER --different atoms of the SAME element
Radioisotopes - --ANSWER --unstable due to excess number of neutrons
Physical half-life - --ANSWER --time for 50% of radioisotope to become stable
Biological half-life - --ANSWER --time required for half of radioactive material from
clinical test to be eliminated from body
Chemical bond - --ANSWER --an attractive force between atoms
What is energy? - --ANSWER --The capacity to do work.
What is chemical work in biology? - --ANSWER --The use of energy in anabolic and
catabolic reactions, such as converting amino acids to proteins.
What is mechanical work? - --ANSWER --The movement of structures in cells and
the whole body, such as cilia beating and muscle contraction.
, What is transport work? - --ANSWER --The use of ATP to transport ions and
molecules against their concentration gradient.
What is chemical energy? - --ANSWER --Potential energy contained in bonds
between atoms, driving nearly all chemical processes.
What is electrical energy? - --ANSWER --The movement of charged particles or
ions, important for nerve conductance and muscle contraction.
Define potential energy. - --ANSWER --Stored energy used to do work, related to
position or contained within a bond.
Define kinetic energy. - --ANSWER --The release/use of potential energy, used to
perform work or chemical reactions.
What is the first law of thermodynamics? - --ANSWER --Energy can only change
forms; it cannot be created or destroyed.
What is the second law of thermodynamics? - --ANSWER --The amount of usable
energy decreases each time energy is used in a reaction, with some energy lost as
heat.
What are reactants in a chemical equation? - --ANSWER --Substances present at
the start of a reaction.
