1.  Collect the diffusion Lab and hand back and review the Energy 2 Test.
 

2.  Cell signaling – Transduction signaling pathway

a) Long distance vs short distance cell to cell signaling..

                2. Life cycle of the lets say Painted Ladies
 
       c) Termination of signals – Phosphodiesterase (stops the Epinephrine secondary messenger cAMP)
          Apoptosis – programmed cell death.

3/16 – Wednesday –  B Day 

 
Main focus –

b) To observe more examples of a cell to cell communication.

1.  Review of the Regulation of the Cell Cycle

2:  Embryonic development – It is an older video and the presenter is a bit froggy but it is a great presentation on embryonic development.  Make sure you dig in!
     
       A) Stem Cell lecture – Holiday lectures
 
 I am asking that you will play the following video with the link below and take notes* on the video
especially on the embryonic development. I will link a google doc for you to do so. Please make notes* to 37:40 min mark.
Make sure you take notes on:
*Remember we left off with a Blastocyst embedding itself on the endometrium wall in the Reproductive cycle form!
 
Stem cell and cell differentiation by chemical messengers for normal development. 
– Germ layers
– cytoplasm factors
 
– CONNECTIONs!! =  (larva lab – painted lady) (Organ Transplants)
 
LINK TO VIDEO:
I will have linked you a google doc for you to complete your notes.    
 
*If these notes are outstanding I will place a 100 in one of the your last forms!
Think NORTS – maybe screen shots!!

3/17 – Thursday –  B Day 

Main focus –                                                                                                                                                          
a)  To observe the larva stage of the life cycle of the Painted Lady butterfly.
 
b)  To identify the changes in the stages of the life of the Painted Lady require cell signaling and cell apoptosis.
 

1.  Painted Lady larva Lab:

Calculating the Biomass in Primary Consumers:

 

A. Weigh one of the cups with a lid.  Write the weight on the outside and code as ‘C” for cup.

B. Tare out the cup (with the lid) and add about 6 grams of mixed butterfly diet. Press the food against the side of the cup.  Write the weight of the food (6 grams) on the outside of the cup and code as ‘F” for food. The food is mixed such that the dry weight is one- third of the total weight after mixing with water.

C. Add 1 – 2 larva per Cup (and lid).  Mass out the entire system (Cup , lid with food and larva).  Subtract this value from the mass of your “C” (cup and lid), F (food).  Write 

Write the calculated weight of the larva on the cup and code as “L”.  The total weight of all these items should be the sum of the numbers written on the cup from the scale.  Next, tare with nothing on the scale, and then weight the entire combination.

2:  Embryonic development – Continue with video at about the 37:40 mark
     
       A) Stem Cell lecture – Holiday lectures
 
–Stem cell and cell differentiation by chemical messengers for normal development. 
– Germ layers
– cytoplasm factors

3/17 -Thursday’s Homework: –

1. Please use your textbook (page 934 –  ) to complete the following form.       

 
1: Immune System Form 2 21 -22:

3/18 – Friday – A Day

Main focus –                                                                                                                                                          
a)  To Compare and contrast the innate and adaptive immune system
b)  To describe the inflammatory response     

 

Cell Cycle – fluctuations – (internal signals vs external fluctuation signals)
                 Internal
 
                             a) protein kinases for cell cycle – Cdk’s (cyclin dependant Kinases) – constant
                             b) Cyclin – fluctuating proteins that bind to Cdk’s —–>  MPF
                             c) Cdk’s —–>  MPF = Maturation Promoting factor
                 
                External
                            
                            a) growth factors (100 known in animals) – cell to cell signaling
                                    example: PDGF  (platelet driven growth factor ) – Fibroblasts have receptors 
                                     for PDFF to that will cause a transduction for the fibroblasts to divide.
                                      Fibroblasts – connective tissue that produces collagen (secondary protein) 
                                                                
                            b) nutrients – without some nutrients cell will not undergo mitosis

 

1. Innate vs Adaptive
2. Leukocytes vs. Lymphocytes
3. Lymphatic system
     (did not get to the Inflammatory response – nor how the current covid vaccines)
 
Notes – on the immune system – non – adaptive (innate) vs. adaptive   
 
immune system review – What connects innate to adaptive?? 
Note taking – 
size of animal = metabolism = Surface to Volume ratio.
checking for health of cells – MHC – I
inflammatory response, fever,
 
                                                     Innate                                    vs                                            Adaptive
                                        1st Response                                                                   Secondary Response
