Nitrogen fixing root nodules. Observing nodules

 We know that plants are important to the ecosystem because they photosynthesize. Did you know that some plants are legumes and these are special because they have ROOT NODULES which are nitrogen fixers.  These root nodules are little rooms where Rhizobium bacteria convert nitrogen gas into ammonium and then Nitrobacter bacterium in the soil  converts ammonium into nitrates. Plants can absorb nitrates to make plant protein.  When those plants are eaten by animals, then animals use the nitrogen to make animal protein.  You can say that all the protein on your body (muscles, enzymes, hair, fingernail etc) was built from nitrogen which was fixed by Rhizobium at some point in time.  




ASSIGNMENT:  10 points

Only certain plants contain these root nodules...amongst them are  bean plants and clover plants.   Look at the morphology of clover plants below.  Look on our school grounds  and find AS MANY DIFFERENT GENETIC VARIETIES as you can.  Upload your clover pic with Frog on a doc or ppt and hand in. 


This picture is from research done by Tashiro et al on the genetics of clover plants.  https://www.researchgate.net/publication/250119450_Leaf_Trait_Coloration_in_White_Clover_and_Molecular_Mapping_of_the_Red_Midrib_and_Leaflet_Number_Traits

Nov 18 lesson: Microbiology. An introduction part 2: BACTERIA


With your teacher,  review the microbe notes on *bacteria* in the introductory notes below. Focus on bacteria, including bacterial taxonomy, shapes, gram+ and gram-.

Hypothesize which area of the school might harbour more bacteria. We will sample the school soon!

Also use this work period to work on current projects and also study for a quiz tomorrow.  I will likely return to school Friday.

Ms. Ng

.........

 This is an Introduction to Microbiology Notes, which cover Virus, and Monerans, with a mention of unicellular fungi.  Read this document as an overview. 

Viruses can infect cells using the LYTIC CYCLE.  

Review the 

STEPS TO THE LYTIC CYLE: memorize AESAR
  • Attachment
  • Entry & degradation of host's DNA
  • Synthesis of new viruses 
    • duplication of virus' genetic material
    • creation of new virus parts
  • Assembly of parts into new viruses
  • Release of new viruses


 video shows lytic cycle




 steps to the lysogenic cycle:  memorize AEIM
  • Attachment
  • Entry (no degradation of host DNA)
  • Integration using integrase enzyme
  • Mitosis
    • Host+virus DNA duplicated
    • cytokinesis
  • A virus that uses the lysogenic life cycle is termed either a provirus or prophage. What causes various proviruses to shift to the lytic cycle is not completely understood, but in some cases stress is the stimulus.

COVID-19 is a virus that undergoes a lytic cycle, but it does not explode cells, instead, it simply gets released from a cell


MICROBIOLOGY ASSIGNMENT 1 What is a virus?  out of /10 
make a creative summary of the  Introduction to Viruses .  This summary must include the lytic cycle  and the lysogenic cycle as it is described in the videos above and also in this text   Viruses can infect their hosts.  

MICROBIOLOGY ASSIGNMENT 2 How does Covid-19 infect a human?     out of /10 
Watch the video above and explain how covid-19 infects a human body. Create a creative summary to describe it


MICROBIOLOGY ASSIGNMENT 3 Evolution and Covid 19.  out of /10 
Review the notes on natural selection, and watch the video on finches below
Read these two articles and create a creative summary explaining how covid-19 mutated through Natural Selection.  Your summary must clearly explain the main points of the articles as well as include the following vocab terms:
natural selection, random mutation, spike protein, ace2 receptor, transmission, replication

Field Trip to the Museum of Anthropology

On October 29,2021, we will visit the Beaty Museum and the Geology Building. We will meet at 11:30 am at the UBC bookstore.  6200 University Blvd, Vancouver, BC V6T 1Z4

We will take attendance and then walk over to the Museum of Anthropology

Website and location is here: MOA

And on maps

We will spend an hour at the museum and then proceed to the Geology museum to look at geology specimens.  At 1:00pm  or 1:30pm students will be dismissed from UBC and students will take the bus back home. 

Please confirm with your parent or guardian and your last block class whether you are returning home or back to school.  

The cost of the field study is: $5.50 for a self led visit.  Please contact me if, for any reason, you would like to apply for a one of our school museum bursaries to attend this trip.
