The people of Finland, who are secluded to some degree from the rest of the world by water, develop certain diseases due to the lack of genetic material from other ethnicities and races.
Physical barriers prevent fish from one stream from mating with fish from another stream, leading to a less varied gene pool among those fish. As time passes, the fish become unable to successfully mate with other groups.
A mountain range prevents two types of goat from mating, causing the gene pool to become less varied.<span>

Answer:
-) Acid-base reaction
-) Carboxylic acid, alcohol, alkene and ketone
Explanation:
For the reaction between acetic acid and triethylamine, we will have an <u>acid-base reaction</u>. Therefore a s<u>alt would be produced</u> in this case an <u>"ammonium quaternary salt"</u>. Also, we have to remember that on this reaction the acid is the acetic acid and the base is the triethylamine. See figure 1
For the second question, we have to check the <u>structure of Prostaglandin</u> E1 in which we have the functional groups:
<u>1) Carboxylic acid</u>
<u>2) Alcohol</u>
<u>3) Alkene</u>
<u>4) Ketone</u>
See figure 2.

Hey there!
Sucrose is C₁₂H₂₂O₁₁.
Find molar mass of sucrose:
C: 12 x 12.01 = 144.12
H: 22 x 1.008 = 22.176
O: 16 x 11 = 176
--------------------------------
342.296 grams
That is the mass of one mole of sucrose.
We have 0.0287.
342.296 x 0.0287 = 9.82
The mass of 0.0287 moles of sucrose is 9.82 grams.
Hope this helps!
