PLZ HELP ME PLEASE DON'T PUT TINGURL OR ANY WEBSITE THANKS Earthquake Information
Read the graph and answer the following questions.

1.How long does it take for a primary wave to travel 2000 kilometers?

2. How long does it take for a secondary wave to travel 2000 kilometers?

3. How far does a secondary wave travel in 10 minutes?

4. How far does a primary wave travel in 10 minutes?

5. What happens to the time difference between primary and secondary waves as the distance traveled gets longer?

6. Suppose a primary and secondary wave both travel a distance of 4000 kilometers before they are picked up by a seismograph. Which wave will arrive first?

7. How much time lag at 4000 lm will there be between these two waves?

8. Suppose both a primary and secondary wave start together and travel for 5 minutes. Which wave will travel farther?

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure

i don't know. if i were you, i would search it up online : d

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

i think that it is c, d, and e, hope this
