AND CORRECT SOLUTIONS ALREADY PASSED
◉ Select all that are correct regarding the stages of labor.. Answer:
expulsion: begins when the fetal head enters the birth canal and
ends with birth of the newborn
dilation: the stage in which the cervix effaces and dilates to 10 cm in
diameter; typically the longest stage of labor taking 6-12 hours on
average
afterbirth: delivery of the placenta and associated membranes
◉ Select all that are correct regarding the size and relative cell
number of the zygote, morula, and blastocyst.. Answer: All
(the zygote is the same overall size as the morula and blastocyst
the blastocyst contains 70-100 cells
the zygote contains a single cell
the morula contains 16 cells)
◉ Place the following events of fertilization in order.. Answer:
1.capacitated sperm burrow through the cells of the corona radiata
surrounding the secondary oocyte
2.after contact with the zona pellucida the sperm bind to receptors
there
,3. the acrosomal reaction causes the acrosome of the sperm to
releases its stored digestive enzymes
4. a single sperm makes contact with sperm-binding receptors on
the oocyte's plasma membrane
5. after reactions to prevent polyspermy the sperm pronucleus
enters the eggs that then finishes meiosis
6. the pronuclei come closer together, their nuclear envelopes
disintegrate, and the genetic material mixes forming a zygote
◉ Select those that are correct about how human blood type is
genetically determined.. Answer: All
(People who have alleles for both enzymes (IA and IB) produce both
surface antigens A and B, so are blood type AB.
People are blood type B if they express an enzyme for the
production of surface antigen B. This allele is designated IB.
The third allele (i) produces a nonfunctional enzyme. People who
have two i alleles have type O blood.
People are blood type A if they have an allele for an enzyme that
facilitates the production of surface antigen A on their erythrocytes.
This allele is designated IA.
People have type B blood can have either the IB IB genotype or IB i
genotype. People have type A blood can have either the IA IA
genotype or IA i genotype.)
,◉ Which is a major event that occurs during the fetal stage of
development? (select all that are correct). Answer: All
(during weeks 9-12 the brain continues expansion, the body
elongates, and ossification continues
during weeks 21-30 there is rapid weight gain, bone marrow takes
over erythrocyte synthesis, axons of the spinal cord begin
myelination and lungs begin producing surfactant
during weeks 9-12 the tube-shaped heart folds and differentiates
into a four chamber heart
during the fetal stage structures and functions of the immature
organ systems formed during the embryonic period fully develop)
◉ Which are correct regarding the types of follicles in the ovary?.
Answer: small primordial follicles are present in newborn females
immature growing follicles are called primary follicles
follicles in which the antrum is large and fully formed are tertiary
follicles
◉ Select all that are normal functions of the uterine tubes.. Answer:
c)Transport the oocyte to the uterus
d)Site for fertilization
◉ Select all of the following that are correct main steps of
spermatogenesis and spermiogenesis.. Answer: spermiogenesis
transforms spermatids into spermatozoa, or fully formed sperm
, spermatogonia undergo mitosis to produce a primary spermatocyte
spermatogenesis begins with mitosis of the diploid spermatogonia
◉ List the anatomical parts in sequence from milk production to
ejection.. Answer: 1.groups of milk-secreting cells are found in
clusters called alveoli
2.alveoli make up a glandular lobe
3. Lactiferous Sinus
4. Lactiferous Ducts
5. Nipple
◉ Select all of the following that correctly identify how the ovarian
cycle and the uterine cycle are interrelated.. Answer: b)
Follicle-stimulating hormone stimulates the development of several
follicles in the ovaries and these ovarian follicles produce estrogen
that stimulates the growth of the endometrium of the uterus.
c)
Luteinizing hormone peaks, stimulating ovulation and development
of the corpus luteum, which produces progesterone and estrogen
that causes the endometrium to continue to thicken in preparation
for possible fertilization.
