Answer:

Explanation:

Hydrogen bonding is usually occur wen interaction with hydrogen atoms occur.

Hydrogen bonds joins DNA polymers because an hydrogen atom occur on on one base which is called hydrogen bond donors and another oxygen or nitrogen atoms on the base across from it which is called hydrogen bond acceptors.

Adenine “A” a purine and Thymine “T” a pyrimidine each have a donor and one acceptor, whereas Cytosine “C” a pyrimidine has one donor and two acceptors, and Guanine “G” a purine has one acceptor and two donors.

This atoms allows for hydrogen bond between them that gives them structure of DNA molecule.

A nucleotides is hydrogen bonded to T nucleotides while C nucleotides is hydrogen bonded to G nucleotide this is called complementary base pairing.

Explain how the melting of the sea ice may affect<br><br> people living on the coast of Florida.
Levart [38]

Since 2000, melting ice from the continent totaled enough to raise sea levels globally by about four tenths of an inch, according to the report which relied on the work of 90 scientists.  With what’s already baked into the atmosphere, faster melting land ice will likely add between 7.5 and 9.8 inches to earlier U.N. estimates by 2100, the report said.  And because of its position downstream, in an area of “preferential excitement,” South Florida could experience rise at the high end as water sloshes around the planet, Kirtman said.  “Think of it as pushing down the ocean [in Greenland]. The ocean is fluid, so it’s going to respond somewhere else and that somewhere else is down here,” he said.  In South Florida, planners already confronting flooding from sea rise have been more aggressive in assessing sea rise.

What is the most likely explanation for the results in the graph?
Delicious77 [7]

Answer:

B. The apple orchard releases toxic chemicals into the water of the  bay.

Explanation:

Option B is the correct answer. It is the most likely explanation for the results in the graph.

From the graph, we can see that the population of the fishes sharply dropped. Since the fertilizer is applied to the apple orchard and the orchard was planted beside the bay, during the rain it is possible that the water has washed some of the fertilizers into the bay. The chemicals used in making fertilizer are harmful and toxic.

This reveals that the toxic chemicals released from the apple orchard are responsible for the decline in the population of the fish.
