o Punctuated Equilibrium

o Evalutation Timeline

Topic

Number One

Review

Darwin verses Lamarck

Key differences in vocabulary

Lamarck

Acquired Characteristic

Law of Use and Disuse

Darwin

Struggle for existence via Malthus

Competition and survival of fittest via Wallace.

Remember 4 Examples included those found in the text.

What neither knew was the source of diversity in traits in a population.

The idea of adaptive radiation is a noun..it is a concept that proposes the the more diverse the population the easier it is for that population to radiate and adapt to a larger range of areas.

Lab due at end of the week

Topic

Number Two

So whose theory did Darwin argue with?

Darwin verse Lamarack

Darwin’s argument

A yahoo version

https://ca.answers.yahoo.com/question/index?qid=20081117214639AAYoR72

An more academic version

http://www.plosin.com/work/OneLongArgument.html

Lets revise..and simply

If a population grows without any limiting factor is grows at a geometric rate.

Geometric growth leads to over population

Yet there is no over population and this is due to “a struggle for existence” ( related to economics idea by Malthus)

Part two

With a population, the is a diverse range of how a trait is shown. (think about a litter of puppies).

Those traits that allow the species to survive, are passed onto the next generation.

The mechanism that select which traits are passied onto the next generation is a natural selection.

Note..”survival of the fittest” was not first written by Darwin.

https://en.wikipedia.org/wiki/Survival_of_the_fittest

Also

Wallace also noticed a selection process by natural sources in his collection of animals.

http://people.wku.edu/charles.smith/index1.htm

The main focus of Darwin’s argument was to challenge Lamarck’s idea that individual species changed with time due to use and disuse of traits.

He used fossil records and data acquired in his five year voyage to propose “the origin of the species”.

In regards to his interpretation of changes in beak structure of finches, we should not that

Each island had limited predation, a unique habitat that created a variety of food sources. These factors within the environment were used to support his argument.

Focus Questions:

Is a theory a fact?

How does the scientific method provide structure to create a theory?

How are direct and indirect evidence used to replace an actual experiment that validates Darwin’s ideas?

Is there a way to create an experiment that could validate the mechanisms of evolution?

For Darwin, what selects a trait?

How does this differ with Lamarck?

What is a common missing factor that both Darwin and Lamarck did not know about?

How could you disprove Lamarck idea of an acquired characteristics?

Take Home Message

A theory is a form of an objective argument based upon evidence that is usually used to support a hypothesis that has been replicated in a variety of formats.

Theories can change with time and they are not facts.

To create a logically sound argument, it is wise to examine objective evidence that both supports and argues the premise that you are defending.

Do not go into a battle of wits with an unarmed opponent.

Bio 12 (2016-17) Lesson 48 action potential

Biology 12 (16-17) L 48 Date: May 8

Last lessons Objective	1. Intro to Nervous System	Evaluations
Today’s Objective	1. Review Neuron structures 2. Action Potential 3. Action Potential Sheets
Topic One	It is a neuron and not a nerve! Intro video https://www.youtube.com/watch?v=DLN1UsvmVvM Tricks: There are five distinct cell structures that allow you to classify three neuron types. Key questions: Were is the cell body? Which is longer, axon or dendrites? Which cell types have myelin 2 minute lesson https://www.youtube.com/watch?v=6qS83wD29PY
Topic Two	How do you make a wave? Lets start with basic wave structures. You have a high point and a low point. On a y axis, this high and low in action potentials is in millivolts. Simplified, voltage is the amount of “push”. Bozeman https://www.youtube.com/watch?v=HYLyhXRp298 So breaking it down into three steps there is Depolarization Inside the actual neuron, the voltage is shifting from negative to positive. This is done by the inflow of sodium into the axon. Outside of the axon, the charge shifts from positive to negative. Note which way “the wave” moves. Repolarization Once the action potential reaches it’s peak, then the charge needs to shift from positive to negative. Now, potassium moves out of the cell, shifting the voltage back to negative. Recovery Period Now the cell become too negative and so some fine tuning is needed via active transport, to move some sodium in and at the same time move potassium out. So let’s find some “links” to visualize this process. A simple step by step video https://www.youtube.com/watch?v=ZAmUjvgoO0A Khan academy feedback https://www.khanacademy.org/science/biology/human-biology/neuron-nervous-system/a/depolarization-hyperpolarization-and-action-potentials Entering “sodium gates” https://www.youtube.com/watch?v=qDUjVzVq7xE Like this one https://www.youtube.com/watch?v=ooI7xT59hE8
Topic Three	So here are some key focal points 1) It is the movement of Sodium going into the cell and the movement of potassium going out of the cell that generates “the wave”. 2) This wave can be faster by moving from “node to node” verses opening several gates in a sequence. 3) Action potential starts with a specific electrical voltage within the axon. This is an all or nothing phenomena. You either have the initial voltage to start the wave or you have no message sent. 4) This process involves four protein carriers. One is active transport during the recovery period. 5) If you think you have seen this graph before, you are right. Remember the circulatory system?

Topic

Number Three

Problems to solve:

· What is Monera?

· Classification of Monera

· What do bacteria do?

· How to observe bacteria

General characteristics of the kingdom Monera are as follows:

• They are primitive organisms.

• All organisms of the kingdom are prokaryotes.

• They are present in both living and non-living environment.

• They can survive in harsh and extreme climatic conditions like in hot springs, acidic soils etc.

• They are unicellular organisms.

• Membrane bound nucleus is absent.

• DNA is in double stranded form, suspended in the cytoplasm of the organism,referred as nucleoid.

• A rigid cell wall is present.

• Membrane bound cellular organelles like mitochondria are absent.

• Habitat – Monerans are found everywhere in hot springs, under ice, in deep ocean floor, in deserts and on or inside the body of plants and animals.

• Nutrition – autotrophs – can prepare their own food, heterotrophs – depend on others for food, saprophytes – feed on dead and decaying matter, parasitic – live on other host cells for survival and cause, symbiotic – in mutual relation with other organisms, commensalism – it is where one organism is benefited and the other is not affected, mutualism – where both the organisms are benefited.

• Respiration – respiration in these organisms vary, they may be obligate aerobes – the organisms must have organisms for survival; obligate anaerobes – the organisms cannot survive in the presence of oxygen; facultative anaerobes – these organisms can survive with or without oxygen.

• Circulation – is through diffusion.

• Movement – is with the help of flagella.

Reproduction is mostly asexual, sexual reproduction is also seen. Asexual reproduction is by binary fission, sexual reproduction is by conjugation, transformation and transduction.

Key Points

· Kingdom verse Domain

· By structure and by function

· Defining what is a primitive structure

· Defining by metabolism
