mitosis and meiosis
Process that create gametes
Meiosis
a fertilized egg
zygote
Function of the placenta
function of the ovary
produce eggs and release hormones
Asexual reproduction produces what kind of offspring
identical
Process that create somatic/body cells
Mitosis
Function of the male reproductive system
produce and deliver gametes (sperm)
do mother and fetus blood mix
no
where the placenta forms
uterus
name two reproductive hormones
estrogen, testosterone, progesterone, LH or FSH
In human development, what comes first meiosis or mitosis
Meiosis
Function of the female reproductive system
produce gamete (egg) and provide place for internal fertilization and development
Structure where fetus develops
uterus
name one female reproductive system hormones and what its role is
estrogen - controls release of egg
progesterone - maintains uterus lining
LH - begins build up of uterus lining
FSH - starts egg development
What is the main function of the endocrine system
maintain homeostasis
Explain how different cells types can develop from the same embryo
the cells have identical genetic instructions (DNA) but different parts of these instructions are being expressed in each cell
Effect on fetus when mother drinks alcohol OR when mom smokes
drinking alcohol - FAS - fetal alcohol syndrome OR
smoking - low birth weight
day of menstrual cycle when ovulation occurs
on or around day 14
Genetic material or genetic information
DNA or chromosomes
The event that occurs in Meiosis that creates genetic variety
crossing over
Put these in the correct order: mitosis, differentiation, meiosis, fertilization, birth, zygote
meiosis -> fertilization -> zygote -> mitosis -> differentiation -> birth
where nutrients and oxygen diffuse from the mother to the fetus
placenta
meiosis takes place here and where fertilization takes place here (2 different places)
ovary and oviduct (fallopian tubes)
enzymes are an example of what type of organic molecule
protein
