directions: watch the animate quantitative** observations about
record two **quantitative observations about mitosis on the lines below.
mitosis observation #1 :
mitosis observation #2:
remember that quantitative means numbers
chrom
mitosis:
before int
chromosomes 46
chromatids 46

Explanation:

Quantitative observations use numerical data. From the visible mitosis table and standard cell biology facts:

1. The table shows a human cell has 46 chromosomes before mitosis starts.
2. After DNA replication (pre-mitosis), each chromosome has 2 chromatids, so a human cell has 92 chromatids during prophase/metaphase of mitosis; also, mitosis produces 2 genetically identical daughter cells from 1 parent cell.

Answer:

Mitosis Observation #1: A human cell has 46 chromosomes before mitosis begins.
Mitosis Observation #2: Mitosis results in 2 identical daughter cells from one parent cell.
