Meiosis

• For Practicum III, learn:
– The name of each process resulting in the production
of male & female gametes
• Spermatogenesis & oogenesis
– The name of each male & female gamete
• Spermatozoa & ovum
– The number of gametes produced in female and in

• 4 spermatozoa & 1 ovum
– Name and number (3) of polar bodies produced in

Urinalysis
(Measuring the Urine Composition)
• Follow 13B Procedure on p243
• Perform the following tests:
–
–
–
–
–
–
pH (acidity): average = 6
Clinistix (glucose): average = 0
Ketostix (ketones): average = 0
Hemastix (blood): average = 0
Albustix (Proteins): average = 0
Blistix or Ictotest (bilirubin): average = 0
• These components are not normally seen in urine
• Record your result on your lab report, p255
– Table 13.2: work in groups to find the associated disorder or
disease for each abnormal result. Abnormal components of urine
and associated disorders are found in your textbook, page 528,
figure 15.1
Bilirubin Test
• Cut off a square piece from the sheet
• Put test square (mat) on paper towel
• Place 10 drops urine on square (used pipette
goes into regular trash)
• Place 1 tablet on square. Do not touch the tablet
• Add 1 drop of water onto tablet and wait 5sec
