The term Southern Oscillation most nearly refers to which of the following?
Yuki888 [10]

The term Southern Oscillation most nearly refers to a reversal of wind direction

Answer: Option D

<u>Explanation: </u>

Southern Oscillation, a component of the atmosphere in one large-scale interaction called El Niño / ENSO. The equatorial cycle fluctuates after irregular periods of about many years in response to alter in atmospheric pressure in the tropical Indo-Pacific.

With the weakening of the east-west wind during the southern oscillation phase, warm water may slide back west, increasing the flow of the equator up. Surface water temperatures and sea levels fall west and rise east, which is why this event is called El Niño.

What is present in human blood that ensures blood ph is maintained at about 7.4?
Anvisha [2.4K]
Bicarbonate buffer system. Human blood contains large amounts of carbonic acid, which is a weak acid, and bicarbonates, a strong base. If blood pH falls below 6.8 or rises above 7.8, one can become sick or die. This bicarbonate buffer system help maintain blood pH at 7.4. The bicarbonate neutralizes excess acids in the blood while the carbonic acid neutralizes excess bases.

Reviewing Main ideas

1. Replication assures that every cell has a complete set of identical, genetic information and makes a copy of the DNA so it can be passed to the new cell. ... DNA polymerase binds the nucleotides together and forms new strands complementary to each template.

2. DNA is a double helix. So during replication, it unwinds and separates into 2 strands. 1 strand will be called the non-coding and the other will be called the coding strand.

The non-coding strand will be the template for the new one.

3. The DNA Polymerase detects if there is an error, it removes the incorrect nucleotide and replaces it with the correct one.

Critical Thinking

4. The main function of DNA polymerase is to synthesize DNA from deoxyribonucleotides, the building blocks of DNA. ... By contrast, RNA polymerases synthesize RNA from ribonucleotides from either RNA or DNA. When synthesizing new DNA, DNA polymerase can add free nucleotides only to the 3' end of the newly forming strand.

5. Why is it important that human chromosomes have many origins of replication? because cells need to be copied quickly to replace cells in our bodies that have died, having many origins of replication helps the process happen faster.

The words that are in bold are the words you should write down. You don't have to write the whole thing. The other words are just for a better understaning.
