Which waste substance normally diffuses across the placenta from the embryo to the mother?
Glucose
Oxygen
Amino Acids
Carbon Dioxide
After a zygote is formed, stem cells turn into specific types of cells. Through which process do the cells of a zygote become specialized?
fertilization
meiosis
differentiation
Which statement best describes an important
process carried out by structure X?
Milk passes from the mother to the fetus.
Materials are exchanged between fetal and maternal
blood.
Maternal (mother's) blood is turned into fetal blood.
The fetus and the mother exchange materials between them such as oxygen, carbon dioxide, nutrients, and waste. This exchange of materials happens using the...
Placenta & Umbilical Cord
Uterus & Umbilical Cord
Vagina & Placenta
During which developmental stages does the "baby" focus on forming new tissues, organs, and body systems?
Zygote Stage
Embryo Stage
Fetus Stage
What is the major change that occurs during the final "fetal" stage of development?
The fetus grows in size
The fetus begins to form new organs
The fetus's cells differentiate into specific cells
Which sequence best represents the correct order of events in the formation of a sexually reproduced individual?
embryo → zygote → gamete → fetus
zygote → embryo → fetus → gamete
gametes → embryo → fetus → zygote
gametes → zygote → embryo → fetus
Which organ is CORRECTLY paired with its function of human reproduction and development?
Uterus : release of gametes
Fallopian tubes : fertilization of gametes
Umbilical Cord : implantation of the fetus
Which EARLY process happens during the ZYGOTE stage of human development?
The zygote forms new organ systems
The zygote takes in nutrients to grow larger and larger
The zygote uses rapid Mitosis
Which is arranged in the correct sequence? [HINT: The Meiosis in this question occurs in the parents]
fertilization -> embryo development -> meiosis -> birth
embryo development -> meiosis -> fertilization -> birth
meiosis -> fertilization -> embryo development -> birth
fertilization -> meiosis -> embryo development -> birth
Placenta previa is a medical condition that occurs in some pregnant women. Women with this condition are often placed on bed rest, which prohibits them from any strenuous activity that may cause the blood vessels in the placenta to rupture. If not diagnosed, placenta previa can be a very dangerous condition because the placenta is
the primary source of oxygen for the mother
where the fetus obtains milk from the mother
where nutrients and wastes are exchanged
the primary source of estrogen and
progesterone in the mother
To clone a mammal, a cloned embryo is often put into an adult female of the same species to continue internal development. The structure in which the embryo will develop is the
ovary
placenta
uterus
egg
During a woman’s menstrual cycle, ovulation occurs and an egg is released. This process is important because it allows for
eggs to be produced by mitosis and be fertilized by a sperm
sperm to fertilize the egg in the uterus
multiple sperm to fertilize one egg, which
then forms the placenta
the egg to leave the ovary and be fertilized by a sperm
