Last lessons Objective

Pesky Protist Project (Due next Wednesday)

1.   How to compare and contrast

2.   Split in the road

3.   Protist vs Fungi,Plant,and Animals

Number One

Consider that an activity of life is something you can observe, either quantitatively or qualitatively.

A concept is using a group of observations to explain an association between those observations.

Number Two

Groups divided into 3 groups\

To compare similarities and differences between observations (activities of life) and concepts (big ideas in biology).

Use Bio 11 “Bio Intel Mission One” to decide what work needs to be done.

Number Three

To organize your group task consider the following

·      How does a biologists use a dichotomous key to compare different types of living things?

·      How do observations lead to concepts?

·      What would be useful tools or terms to have in order to navigate into new worlds?

Wound antiseptics and sterile techniques

https://meds.queensu.ca/central/assets/modules/basic_suturing/wound_antisepsis_and_sterile_technique.html

Focus question

With each technique what is being cleaned or killed?

How did sterile technique save lives?

Number Two

A “gram” stain is a means to identify if a bacteria has a cell wall or not.

We use two stain, one to stain the cell wall and the other to stain the cell membrane

Gram stains can also be used to identify pathogenic bacteria

Source for bacteria will be yogurt

You will make a slide, draw what you see and then research what bacteria are found in yogurt.

Number Three

Next class we will design an experiment to test a gram positive and gram negative bacteria.

Here are some references to discuss the biology of gram positive and gram negative bacteria

o

Number One

What are the structures of viruses?

How does a virus “adapt”?

Looking at my virus top ten notes, notice five ways to debate that a virus may or may not be alive.

While it does show some similar activities of life, a virus is not a cellular and self maintained structure.

The riddle is..how did a virus gain DNA or RNA. In fact, it is truly the first “chicken verses egg” story.

The old system say that viruses can be classified by the host that they infect ..

The new system is more complex!

1.   How has the classification of viruses changed with the increased information on viruses?

2.   Can viruses evolve?

3.   Why do standard methods of taxonomy not work for virus?

4.   What evidence for viruses being alive are being used related to their classification?

Looking up myths about viruses and the first thing you find is computer viruses!

Which came first the actual biological virus or computer viruses is quite obvious.

·      It is both alive and not alive.

·      It is both lethal and yet can be linked to evolution. You take antibiotics for bacteria yet they are of no use for viruses.

Truth is stranger than fiction.

Last lessons Objective

2.   Evolution’s patterns

3.   Using DNA to link Taxonomy and Evolution

o

Number One

The role of protein synthesis is to make proteins.

Proteins are made from having or not having the code in DNA. For simplification, this is referred to as “a gene”

It is currently a theory that for each gene there is a protein.

The role of genetics in evolution became clearer when Hardy and Weinberg showed that the frequency of a particular allele or trait in a population influenced how that population could evolve. (Chapter 6)

Number Two

Taxonomy can be seen as a means to take the diversity of life and create an orderly system based upon classification.

This system came about to have a universal means to classify living things using a language that was not subject to change.

Using a dichotomous key, a series of yes or no questions allows the classifier to go from a whole group to specific genus and species.

A cladogram or family tree can show both taxonomy and evolutionary trends

To classify we go from:

Kingdom,Phylum,Class,Order,Family,Genus and Species

A species includes the genus that it came from.

Evolution looks at how species are formed and the mechanisms that allow genetic information to be displayed.

In chapter six, we note that genetic material influences how traits can be displayed within a population.

Genetic information can flow between populationsn.

A population has a “gene pool”

Traits within a population can shift and evolution can select traits, which causes gene frequency to “drift” from one frequency of alleles to a different value.

Number Three

Prokaryotic: Pre chromosome cells (Monera)

Eukaryotic: True cells with chromosomes and membrane bound organelles.

While the actually origins of life on the planet is still a theoretical idea, we can now use genetic traits and dna to show an indirect proof of how life has evolved.

All species lead back to a universal ancestor cell. This cell was probably prokaryotic.

Family trees and cladograms attempt to trace the lineage of how this ancestor cell changed with time.

Watch taxonomy video!

We now have three “domains” verses kingdoms to show both a genetic and taxonomical history of living things on earth.

Bacteria, Archea and Eukaryea are the three domains.

This form of classification helps to clear up a previous taxonomical system that had no information on genetics and gene interactions. It also considers the metabolism of simple prokaryotic cells that used to be classed simply as monera.

Evolution attempt to understand the origin of a species and how species can diverge or converge.

DNA is the universal “language” of all living things. It is a molecule that can change with time and it can influence the mechanisms of evolutionary change
