Density Quiz   Weds. Jan. 7th   Practice problems!!

Formulas to remember: D=M/V  density equals mass divided
                                                        by volume
                                          V=M/D  volume equals mass divided
                                                         by density
                                          M=DxV mass equals density times
                                                           volume
mass is measured in grams(g), volume in cm cubed or mL,
and density in g/mL or g/cm cubed

*Human Development and Comparative Embryology Quiz Thursday,  10/24*          Review every night!

                                                             Power Words

• zygote- the single cell formed from the union of male and female sex cells
• embryo-the first 8 weeks of embryonic development
• fetus-the unborn, young organism having a basic structural resemblance to the adult animal.  All major organs are present at this time.
• fertilization-the union of male and female sex cells during sexual reproduction.  In plants, this is called pollination and in humans it is called insemination.
• phylogeny- the embryonic development of a related group of organisms, like vertebrates.  They are all in the same phyla.
• ontogeny-the embryonic development of a single species, like humans.  

zygote- 1 cell
embryo- 1 million cells
newborn- 2 trillion cells
adult- 100 trillion cells
