BIO 235 MIDTERM 1 EXAM
QUESTIONS AND DETAILED
CORRECT ANSWERS; A+ GRADE
"blast" cells - correct answer- immature cells
that secrete the ECM
"cyte" cells - correct answer- mature cells that
maintain the matrix
2 layers of serous membrane - correct answer-
-pariteal-attached to and lining a cavity-outer
-visceral-inside and covers and adheres to organs in
cavity-inner
3 things that effect growth in the body size - correct
answer- 1. increase in the size of existing cells
2.increase in the number of cells
3.increase in the size of material between the cells
,A band - correct answer- darker middle part of
the sarcomere extending the entire length of thick
filaments-at the end of the band is a zone of overlap
where thick and thin filaments lay side by side
A site - correct answer- aminoacyl site binds
the tRNA carrying the next amino acid and the amino acid
from P gets added. first site on the right
abdominopelvic cavity - correct answer- from
the diaphragm to the groin
abdominal cavity-stomach, spleen, liver, gallbladder, small
intestine, and large intestine
pelvic cavity-urinary bladder, parts of the large intestine,
and internal organs of the reproductive system
abduction - correct answer- movement of bone
away from midline
Acetylcholine (ACh) - correct answer- inside
each vessel and is the chemical released at the NMJ
,ACH receptor - correct answer- within each
plate there are millions of these receptor which are
integral membrane proteins to which ACh specifically
binds to
acid - correct answer- a substance that
dissociates into one or more H atoms and anions
acidic solutions pH - correct answer- H is
greater than OH and ph is less than 7
acidoses - correct answer- blood ph falls below
ph of 7.35
acinar gland - correct answer- rounded
secretory part
acorimal end of clavicle (lateral) - correct answer-
broad flat and articulates with acromion of scapula
, acromion of scapula - correct answer- lateral
end of spine projects as a flattened expanded process-
high point of shoulder
actin - correct answer- thin filaments jon
together to form an an actin filament that looks like a
helix and has a binding site where myosin head can attach
activate transport - correct answer- polar or
charged molecules-energy required to move across
membrane (ATP) against the gradient
activation energy - correct answer- collision
energy needed to break the chemical bonds of the
reactants so a reaction can start
active processes - correct answer- cellular
energy is used to drive substance "uphill" against its
gradient
