The picture is a scientific model which is used to explain the concept of the water cycle by means of pictures and descriptions.

<h3>What is a scientific model?</h3>

A scientific model is a representation which may be in form of pictures, illustrations, objects, or ideas which are used to explain a particular concept by scientists.

Scientific models are usually employed to explain either difficult to understand concepts or scarcely observable phenomena in order to enrich the knowledge and comprehension of others.

The given illustration is an example of a scientific model. It is used to explain the concept of the water cycle. By means of pictures and descriptions, the various processes of the water cycle can be fully comprehended.

Also, by means of a cyclical illustration, the model helps to explain that the water cycle is a continuous repetitive process.

In conclusion, scientific models may be in form of pictures, illustrations or objects.

Hypothesis A: If heart rate is related to caffeine intake, then coffee drinkers will have higher heart rates.

Katen [24]

Answer: D. Hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

Hypothesis A and B both are suggesting that caffeine intake is related to higher heart rate. But hypothesis B is proving it more certainly by suggesting the affects of caffeine intake on heart rate. As, heart rate of most people will be higher 30 minutes after they drink a cup of coffee is testifying the fact, that higher heart rate is related with caffeine intake.

Therefore, hypothesis B is more useful because it suggests a way to test the relationship between heart rate and caffeine intake.

The human genome contains about 3 billion base pairs. During the first cell division after fertilization of a human embryo, S ph

Nataly [62]

Answer:

5556

Explanation:

If a DNA polymerase synthesizes in average 50 nucleotides/second, that means that in three hours (10800 seconds) it synthesizes about 540000 nucleotides.

However, if the human genome is composed of 3000000000 (3 billion) base pairs (nucleotids), the minimum number of DNA polymerases (working in the same number of origins of replication) to finish the duplication of all the genome in three hours is 5555,5. (3000000000/540000). As we know there is no half polymerase, so we round to 5556.

5556 molecules of DNA polymerases acting on 5556 origins of replication are needed.

Explain in your own words?

Oksanka [162]

Answer:

There are many green house gases and carbondioxide is one of them. Green house gas has the ability to stop the heat from going to the atmosphere. This heat energy reduces the atmospheric carbondioxide to dissolve in the ocean water so more concentration of carbondioxide is present in the atmosphere which stop the reflected sunlight rays into the space and thus increase the temperature of the earth surface. This increase in temperature called global warming.
