What do you know about earthquakes?

From class, earthquake is any shaking or rapid motion of the Earth's solid layer. the plate tectonics cause stress on rocks which leads to breakage and breakage causes energy which causes earthquake :) 

There are also different types of Earthquake waves such as P. Waves, S. Waves, and Surface Waves

-P.Waves: "Primary" or "push-pull" and it travel faster than other waves

-S. Waves: "Secondary" or "side-to-side" and it leaves the epicenter at the same time as the P. Waves but travel slower and it reaches the location after the
P.waves hit

-Surface wave is the strongest and it only travel on the crush. it is a combo of the P. and S. waves

An earthquake is the sudden release of energy from the crust of the Earth, that results in a seismic wave. Using a seismograph, the interior of the Earth is mapped, finding the epicenter (origin) and magnitude (strength) of the quake.

What is the layer of stem cells that constantly divide to renew the epidermis?
Mnenie [13.5K]

Answer: I think, I may be wrong, but I think the answer is stratum basale.  i <em>found this online</em>

Explanation: The topmost layer is dead and sheds continuously. It is progressively replaced by stem cells that divide in the basal layer (stratum basale). The dermis connects the epidermis to the hypodermis and provides strength and elasticity due to the presence of collagen and elastin fibers.

What would be the best negative control to use when testing for any organic compounds
ra1l [238]

Explanation:

A similar question was asked online, here is the answer it gave:

'“Negative control” is a treatment that by definition is expected not to have any effect (neither positive effect, nor negative effect). “Positive control” is treatment with a well-known chemical that is known to produce the expected effect with the assay that you are studying. Application of an antagonist is not a negative control in your case. “Negative control” is condition that should be treated with the same solutions or buffers as your “treatment” condition, with the only difference that instead of the chemical that you investigate you should add just the solvent that was used to dissolve you chemical in the respective final concentration that you have in the “experimental treatment” condition. For example if your chemical is dissolved in DMSO – than the correct negative control will be to add to the medium/buffer just DMSO in the same final concentration that you reach with your “treatment” condition. One of the reasons of using such negative control is to verify that the solvent is having no effect in your assay. Note that among all treatment conditions (“negative control”, “positive control”, “experimental treatment you are investigating”) the volumes and the composition of the treatments that you are doing should be uniform: always treat with the same volume of medium or buffer, always containing the same concentration of the used solvent (e.g., DMSO). The only difference should be the presence or absence of the defined compound-treatments (agonist, antagonist, the chemical for the experimental investigation etc.).'

My best advice is to use the textbook you have, or use examples of a negative control when testing organic compounds because you have to find something that you can assign, like a worm in a box of dirt, the worm could have enough food to survive, so that is your negative control, but when it comes to finding the best, that would have to rely on something within the parameters of being self sufficient like a plant getting its energy from photosynthesis, etc.
