How was the SAT? How's your week going?
While I do: HOMEWORK CHECK! (Cell Cycle & Mitosis notes from Tuesday, 2/25 blog post); no late credit for this - you've had a week and a half and class time to do it. 😁
Coronavirus updates:
First, a short, funny video from The Daily Show here
live blog HERE (10 mins max)
What is the Coronavirus and what should I do if I have symptoms?
Hand sanitizer vs. soap and what the CDC says
What's PPS saying about it?
Today's Agenda:
-Finish Mitosis Investigation & Microscope Lab
-Background information on genetics & cancer (notes handout HERE)
Next...4) What happens if mitosis cell signals change over time?
Explore connection between cell signaling and cancer.
Background information: (notes handout)
-In humans, each cell normally contains 23 pairs of
chromosomes, for a total of 46.
-22 of these pairs, called autosomes, look the same in both males and females. The 23rd pair, the sex chromosomes, differ between males and females. Females have two copies of the X chromosome, while males have one X and one Y chromosome.

Today's Agenda:
-Finish Mitosis Investigation & Microscope Lab
-Background information on genetics & cancer (notes handout HERE)
1) Complete Mitosis Investigation and Microscope Lab using slides HERE (set up microscopes to finish and/or for absent students to view cells)
2) Share out mitosis data: write percentages for each stage of mitosis on board per class period; compare
3) Learn important background information on genetics

An organism's genotype is the set of genes that it carries.
An organism's phenotype is all of its observable characteristics — which are influenced both by its genotype and by the environment. ... For example, differences in the genotypes can produce different phenotypes.
