Answer:
can you give me more information
Answer:

aka Ethenone
Explanation:
Ethenone is an organic compound made out of the elements Carbon, Hydrogen, and Oxygen. It is an example of a covalent molecule. The Hydrogens are single bonded to the carbon and then the carbons and oxygen are double-bonded to each other. Additionally, because there are 2 Hydrogens and 1 Oxygen the ratio is 2:1, as stated in the question.
Answer:
(C) Only BamHI and BglII fragments are compatible.
Explanation:
First we can visualize how the enzymes cut by completing the strand below and cutting where indicated. The three enzymes cut with cohesive ends.
Then we can complete the sense of the strands and serach compatible ends. Keep in mind that we can only join 5 'ends with 3' ends.
BamHI = G...3' 5'...GATCC
CCTAG...5' 3'...G
XbaI = T...3' 5'...CTAGA
AGATC...5' 3'...T
BglII = A...3' 5'...GATCT
TCTAG...5' 3'...A
In bold, leave the bases that remain in single strand and must be compatible with those of the other end.
To be compatible they must be complementary bases. A with T and C with G.
Now you can see that only BamHI fragments are compatible with those of BglII.
Answer:
Oceans upwelling decreases, reducing levels of nutrient-rich water
Explanation:
Typically, trade winds blow from east to west in the Pacific pushing warm surface ocean waters towards Asia. This causes upwelling of cold ocean currents from the depths of the oceans on the west coast of South America bringing up nutrients from the depths.
During Elnino, however, these trade winds weaken, and predominant winds blow eastwards, reducing this upwelling of colder deeper waters.
