Compare and contrast the four types of memory; episodic memory, semantic memory, working memory, and procedural memory.

Then on neuron one show me what the neuron is like at resting state, please include:

a. sodium potassium pump The sodium-potassium pump (PDB entries 2zxe and 3b8e ) is found in our cellular membranes, where it is in charge of generating a gradient of ions. It continuallypumps sodium ions out of the cell and potassium ions into the cell, powered by ATP.

b. sodium Na+ It's also called a serum sodium test. Sodium is an essential mineral to your body. It's also referred to as Na+. Sodium is particularly important for nerve and muscle function.

c. potassium K+ The chemical notation for potassium is K⁺. The proper level of potassium is essential for normal cell function.

On neuron two show (via a drawing) me what happens during an action potential (depolarization), describe what happens to the voltage within and without the neuron. Include the movements of the Na+ and K+ ions.

On Neuron three show me via your drawing how a neuron goes back to resting state. Describe the movement of Ions across the neurons membrane and show me where all this takes place on the neuron. Please include hyperpolarization.

Similarly to assignment one, I want you to draw me a close up picture of a synapse (what happens between the Axon terminals of the presynaptic neuron and the dendrites of a post synaptic neuron communicate). Please take a picture of your drawing and attach it to the assignment, in lieu of this write up a document that parallels this assignment as close as possible and attach that to the assignment instead.  Include the following elements and describe briefly what they are doing to produce a synaptic event.

a. vesicles

b. neurotransmitter - explain where it is and what it does

c. synaptic gap

d. reuptake mechanism - describe its function and how it works.

e. receptors

f. extra credit calcium and its channel

As you may know, gene transcription begins with the assembly of the transcriptional machinery (TFIIA-H proteins) at the core promoter of genes. Where do you think core promoters are more likely to be located? Nucleosome DNA or Linker DNA?

Go ahead and formulate a hypothesis on the more likely location of core promoters of genes in DNA, and defend it with molecular biology arguments (in other words, why would one or the other be a preferred location for core promoters, based on what you know about nucleosome DNA and linker DNA?).

Then, I want you to imagine that you have access to a standard molecular genetics lab, and I want you to propose an experimental test of your hypothesis. You don’t need to get too technical, just a description of how you would design an experiment that tests your hypothesis, indicating samples, treatments, and the measurements or readouts that that you plan to take. Your imaginary lab has the following equipment:

1)  Antibodies for immunoprecipitation: these are molecules that can bind to several kinds of proteins, and allow you to physically pull them down (along with anything that is bound to them). In this case, imagine that you have access to antibodies that allow you to separate any proteins bound to DNA and isolate them along with any DNA bound to them!!

2)DNA sequencer: a machine that allows you to “read” the sequence of a given DNA sample.

3)Core promoter sequences: Information about what a typical core promoter sequence looks like.

So go ahead and design an experiment using any combination of one or more of the resources listed above, and do not forget to describe what results you expect to see, should your hypothesis be correct.

Your submission should be 200 words or fewer,

PLEASE use ONLY the equipment mentioned above.

Compare and contrast Gleasonian vs. Clementsian community Ecology. Provide examples that support each. What is the consensus as to which seems to best describe most communities?

Compare the adaptations of plants in Tropical Rainforests and Temperate Forests

Compare and contrast exotoxins and endotoxins with regard to their: a) chemical nature, b) source, c) effects on human body cells and resulting symptoms, and d) examples.

Which gives off the most energy?

c. translation

d. Calvin Benson cycle

e. cell division

5-8 different features of the native PNW Temperate evergreen forest biome.

Which of the following represents an example of coevolution?

Group of answer choices

Over time, peppered moths shift from having mostly light-colored wings to mostly dark-colored wings.

The majority of human babies are born weighing between 5.5 and 10 lbs.

The flower of the plant species, Centropogon nigricans, is exclusively pollinated by the tube-lipped nectar bat, Anoura fistulata. The bat has the longest tongue relative to its body length of any mammal and it uses its long tongue to reach the nectar inside of the long, thin C. nigricans flower.

Dark mice on lava and light mice on sand are predated upon less than gray mice in either habitat.

The greenhouse effect:

Group of answer choices

A) has caused extreme fluctuations in climate over the past thousand years.

B) causes seasonal differences in day length every year.

C) is primarily caused by humans through burning of fossil fuels and deforestation.

D) is caused by atmospheric gases that trap heat in the Earth’s atmosphere.

E) is synonymous with global climate change – they mean the same thing.
