BIO 131 LAB EXAM 4 STUDY GUIDE 2026/2027 | PRACTICE QUESTIONS, VERIFIED
ANSWERS & COMPREHENSIVE REVIEW
ANIMAL CELLS: Know the difference between red blood cells and white blood cells (1 question) -
correct answer ✔✔red blood cells or erythrocytes are the most numerous and will appear
pinkish with a light center and lack a nucleus.
white blood cells or leukocytes lack a natural pigment and are colorless and have large and
deeply stained nucleus.
Know the function and characteristics of nervous tissue of this tissue (2 questions) - correct
answer ✔✔nervous tissue is specialized for reception of stimuli (perception) and for the
conduction of nervous impulses to muscle cells and glandular cells
Know the functions of white blood cells (1 question) - correct answer ✔✔They detect and deal
with infections or foreign molecules that enter your body
Know the functions of red blood cells (1 question) - correct answer ✔✔They carry oxygen from
our lungs and deliver it through our body
Know the functions of squamous epithelium (1 question) - correct answer ✔✔regulates the
passage of substances into the underlying tissue/allows selective diffusion of materials to pass
through
Know the functions and characteristics of cartilage tissue ( 2 questions) - correct answer
✔✔resists compressive forces, enhances bone resilience, provides support on bony areas where
there is a need for flexibility
Know the functions of the cell (plasma) membrane (1 question) - correct answer ✔✔it forms a
boundary for the cell contents; provides protection for a cell
, Know the characteristics of skeletal (striated) muscle (1 question) - correct answer ✔✔made up
of long cylindrical fibers, appears striated, and has many peripherally located nuclei. It is
responsible for voluntary movement, produces heat, and protects organs.
HUMAN PHYSIOLOGY: Know the functions of alveoli (1 question) - correct answer ✔✔the
exchange of oxygen and carbon dioxide takes place
Know what is discussed about cellular respiration on pg 203 (1 question) - correct answer ✔✔it
is the conversion of the energy of glucose to the energy of ATP. it requires oxygen
Know the equation for cellular respiration and be able to answer questions related to the
equation as presented in this lab on pg 209 (2 questions) - correct answer ✔✔C6H12O6
(gkucose) + O2 (oxygen) --> H2O (water) + CO2 (carbon dioxide) ATP is produced
What area of the body is responsible for producing the greatest accuracy in tactile
discrimination of two points? (1 question) - correct answer ✔✔For me, it was the palm of my
hand
Be able to identify all the independent and dependent variables in section 1,2,3 and 4. There
will be one question from each section (3 questions) - correct answer ✔✔1: Independent is
time in minutes, dependent is pulse and respiratory rate
2: Independent is handedness, dependent is the seconds for each hand
3: Independent is attempt number, dependent is number of elapsed milliseconds
4: Independent is location on body, dependent is minimum distance
What variable can change which will control the amount of blood to cells and tissue? (1
question) - correct answer ✔✔blood pressure or body temperature
