Layer of Earth made up of the crust and upper mantle: 1. lithosphere

long, underwater mountain ranges: 6. mid-ocean ridge

idea that the world's land masses are slowly moving over time: 9. continental drift

magnetic qualities "frozen" into rocks when they are formed showing the direction of the magnetic field at that time: 8. paleomagnetism

describes how Earth's plates move and what happens when they interact with each other: 10. plate tectonics

circulating flow of a gas or liquid due to density differences: 11. convection

force that pulls objects towards the Earth: 12. gravity

boundary where two tectonic plates are moving away from each other: 4. divergent boundary

boundary where two tectonic plates are moving towards each other or colliding: 3. convergent boundary

upper part of the mantle that is........ 2. asthenosphere

boundary where two tectonic plates move in opposite directions alongside each other: 5. transform boundary

place where one plate gets pushed under another plate: 14. subduction zone

deepest part of the ocean; steep-sided canyon: 7. ocean trench

super-continent made of all the continents that existed millions of years ago: 15. pangea

section of the lithosphere that slowly moves over the asthenosphere, carrying pieces of continental and oceanic crust: 13. tectonic plate

*numbers 10 and 13 are the same thing*

how to determine the net charge of the tripeptide Asp-Gly-Leu at pH 7. Can someone show in details and tricks on how to solve it

Ugo [173]

Answer:

Explanation:

You need to search your pKa values for Asn (2.14, 8.75), Gly (2.35, 9.78) and Leu(2.33, 9.74), the first value corresponding to -COOH, the second to -NH3 (a third value would correspond to an R group, but in this case that does not apply), and we'll build a table to find the charges for your possible dissociated groups at indicated pH (7), we need to remember that having a pKa lower than the pH will give us a negative charge, having a pKa bigger than pH will give us a positive charge:

-COOH -NH3

pH 7------------------------------------------------------

Asn - +

Gly - +

Leu - +

Now that we have our table we'll sketch our peptide's structure:

This will allow us to see what groups will be free to react to the pH's value, and which groups are not reacting to pH because are forming the bond between amino acids. In this particular example only -NH group in Ans and -COOH in Leu are exposed to pH, we'll look for these charges in the table and add them to find the net charge:

+1 (HN-Asn)

-1 (Leu-COOH)

The net charge is 0!

I hope you find this information useful and interesting! Good luck!

Explain how a drought poses a threat to life and the biosphere. Use complete sentences.

Marina CMI [18]

Answer:

A drought poses a huge threat to all life. If a drought occurred the entire food chain would disintegrate within months. There would be no water for any animals or plants. Small mammals would not be able to eat plants, and reptiles would not be able to the small animals, and so on. A drought can destroy an ecosystem in a short amount of time.

Water is only being moved into the air through water vapor, so the air will become hotter than water. Land is also not moving in the atmosphere and absorbing heat like air is, so air will also be hotter than land, depending on what the land is made of.

Through precipitation, water in the atmosphere can return to the hydrosphere or percolate into the ground to become groundwater—part of the geosphere. ... Water in the biosphere can be released into the atmosphere through transpiration in plants, or respiration in animals.

According to the rate law, how do concentrations affect rate?

IrinaK [193]

D, the rate increases as concentrations increase.

Typically, reaction rates decrease with time because reactant concentrations decrease as reactions are converted to products. Reaction rates generally increase when reactant concentrations are increased.
