mitosis lab

 The mitosis slides are located in the second back room.  They can be a challenge to look at.  If they can be found then your teacher will assist you in observing these prepared slides .  

Draw mitosis under high power in the light  microscope in 3 pictures. Label the stages of mitosis

steps of cell cycle:  you should write a table showing the steps as well as the
FORM OF DNA
role of other organelles

1.  INTERPHASE -
a.  cell is undergoing growth.  After a period of growth, it prepares to divide
b.  cell replicates its DNA.  Nuclear membrane is still intact
2. PROPHASE
Nuclear membrane disappears and the chromosomes are visible
3.  METAPHASE
chromosomes line up in the middle and Centrioles send out the spindle fibres to attach to the centromere
4.  ANAPHASE
centromeres get ripped apart and thus the chromosomes get ripped apart into separate chromatids
5.  TELOPHASE
nuclear membrane reforms around the chromatids
6.  CYTOKINESIS
chromatin is in the nucleus now.

DNA notes

  Watch my videos on DNA, review the concepts in the slides below  and use class time to complete the assignments which are due on Friday.  

Here is another video from youtube which explains these concepts in more detail.

LESSON: Chemical reactions may be categorized as follows : 

1.     Synthesis

2.     Decomposition

3.     Single replacement

4.     Double replacement

5.     Combustion

       Cellular Respiration

6.     Oxidation of metals

Synthesis reaction:

element     +   element    -->    compound

Decomposition reaction:

Compound    -->   element     +     element

Or

Compound --> smaller compound    +   element

DOUBLE REPLACEMENT


single replacement

IN ADDITION TO THE FOUR TYPES ABOVE, THERE ARE ALSO THREE MORE KINDS of reaction TO KNOW: 

Combustion:  combustion may happen to any *organic compound* meaning any compound made of carbon, hydrogen and/or oxygen...

Carbon based compound+ oxygen --> carbon dioxide + water

+ heat and light energy

Cell respiration looks like combustion,

BUT IT IS NOT. YOUR CELLS ARE NOT COMBUSTING.  The carbon based compound in this case is glucose, a simple sugar.

Glucose +   oxygen -->  carbon dioxide + water + energy for cell

Oxidation reaction

Metal +  oxygen   -->   metal oxide

ACID BASE REACTIONS ARE ALL NEUTRALIZATION REACTIONS

In summary....

 

Liver Anyone?

 

In the human body, ENZYMES help speed up chemical reactions. 

Today we take a piece of raw pork liver and add it to Hydrogen Peroxide.  Raw liver contains an enzyme called "catalase" which has a job of breaking the bonds in hydrogen peroxide.  When those bonds are broken, atoms rearrange themselves and new products are formed.  

In today's lab, we discover the new products

X-linked genes

 SEX LINKED GENES

In the following post, I will refer to the term  "male" and "female".  This refers to people with male sex organs or people with female sex organs.  People with these organs can identify with a diverse range of gender such as:

Man, woman, nonbinary. This gender identify is not presumed by the presence of male or female sex organs

They might also identify as

LGBTQ2S++

The following descriptions are biological descriptions refer to 

male= has male sex organs like testes, producing male gametes such as sperm

female= has female sex organs like ovaries, producing female gametes such as  eggs. 

The sex chromosomes are XX and XY in humans. Some alleles are located on the X chromosome. But very few on the Y chromosome.  Remember that people who are  females have the genotype XX and people who are males have XY.

The Y chromosome carries very little information, only enough to influence the embryo on the path towards male primary and secondary characteristics.

Meanwhile, many RECESSIVE ALLELES are located on the X chromosome, including
1. hemophilia, the inability to clot blood
2. colourblindness inability to tell the difference between red and green colour
3.  baldness

These characteristics are far more common in people with male sex organs  than people with female sex organs because  people with male organs have only one X. And if that X contains the recessive allele, they will show the phenotype.  Meanwhile,people with  female organs may have the recessive and their dominant genes on their other X will protect them.  For example

An example of using a punnet square to calculate probability is here:

Some things to note about sex linkage:  Signs of sex linked alleles are:
1. more genotypic males get the phenotype, but genotypic females can be carriers
2.  males can inherit from mother but not father (because males get their X from mom)
3.  genotypic females have an extra X and this protects them.  Females must be homozygous to show the sex linked phenotype.
Further reading on sex linkage here http://learn.genetics.utah.edu/content/pigeons/sexlinkage/


FYI if you were born a male and you want to know if you're colourblind:  Test yourself here: But careful, if you are a genetically male, you might find out you are colour blind!  Apparently most people find out they are colourblind from their science teacher !

Do the work on this practice sheet on your own piece of paper up to page 11.  If you finish, you can continue your practice.   Take breaks as you need to! This is hard work!

 10 marks for completing this. 

later,  is an activity next week called " Chemistry Karate"  where your chemistry skills will be respectfully assessed by myself and by peers and you will demonstrate your level of chemistry karate belt.  The goal is to move up one belt, not for everyone to be a black belt !
