Did you model weathering, erosion, or both in this lab? Give an example of a step of the lab in which you modeled a process to s
kolezko [41]

Modeling of weathering and erosion can be performed in lab.

<h3>Procedure of Modeling Weathering and Erosion using graham cracker:</h3>

1. Fill the ice cube tray or other tiny containers with 100 drops of water in each of the two or three cells using the eyedropper. Make the water entirely solid by freezing it for however long(for 3-4 hrs.).

2. Insert one graham cracker section into the bowl. To create a ramp-like structure out of the Graham Cracker, place one end on the bowl's lip and the other end at the bottom. To secure the cracker to the side of the bowl, dab some icing on the back of the cracker.

3.Add water to the eyedropper. Hold the dropper at a height of about 1 inch above the cracker's top. the dropper over the cracker in the middle. Apply 100 drips, always aiming for the same area.

4.Keep an eye on what the cracker does. Keep a record of your findings.

5. Pour the water into a glass that is clear after removing the Graham cracker. Make notes about the water, grading its cloudiness among your observations.

6.In the same manner as in step 2, clean and dry the bowl and add a Graham cracker to it. Grab an ice cube and wipe it over the graham cracker until it melts completely.

7.Remove the graham cracker and pour the melted water into the clear glass.

<h3>Result:</h3>

Appearance of water collected after is moved across graham cracker.

How do the diffuse modulatory and point-to-point synaptic communication systems in the brain differ? list four ways?
Vesna [10]

Diffuse modulatory synapses or neuromodulation function different than simple point-to point synapses.

1. Number of postsynaptic neurons

In neuromodulation neuron uses one or more neurotransmitter to regulate several neurons. In Synaptic point-to-point transmission only one particular neuron receives signal from the presynaptic neuron.

2. Neurotransmitter sin neuromodulation (neuromodulators) are not reabsorbed broken down by the pre-synaptic neuron like those in classic synapse. Neuromodulators stay in cerebrospinal fluid.

3. Receptors are also different: the receptors for the neuromodulators are typically G-protein coupled receptors while in classical chemical neurotransmission, they are ligand-gated ion channels.

4. Neuromodulation is a slow process, while classic synaptic transmission occurs fast.

The backlit screens of computers emit enough light to suppress the hormone _____, which normally rises in the evening and orches
san4es73 [151]

The backlit screens of computers emit enough light to suppress the hormone melatonin. This hormone rises in the evening and orchestrates daily rhythms.

<h3>What is melatonin?</h3>

Melatonin is a hormone whose secretion in the brain is connected to sleep (i.e. the time of day or circadian cycle).

Melatonin is produced by the pineal gland as an environmental response to darkness.

This hormone (melatonin) is well known to be involved in different sleep disorders, thereby having therapeutic applications.
