Why are models useful in Earth science?

Biology

solmaris [256]2 years ago

Models are a simplified representation of an object or an idea that describes an event that is too complex, too big or too small to study in real life. These models come in handy when studying geology because scientists couldn't fit the Earth's surface into the laboratory to study it.

In the citric acid cycle, the acetyl group of each molecule of acetyl-coa is converted into two molecules of ________.
Tatiana [17]

In the citric acid cycle, the acetyl group of each molecule of acetyl-CoA is converted into two molecule of carbon dioxide and water. It is the pathway that connects carbohydrates ,fat and protein metabolism.

The cycle which carried out by eight enzymes that completely oxidase acetate by which two carbon molecules in the form of acetyl -CoA into two carbon dioxide and water molecules.6- carbon glucose molecule is split into two 3- carbon molecules called pyruvate , which needs in order to create acetyl CoA.

Citric acid cycle is also known as krebs cycle or TCA cycle it is the series of chemical reactions to release to releases stored energy through the oxidation of acetyl-CoA from carbohydrate, fats and protein.

Which statement BEST characterizes the general relationship between air pressure and elevation?
Ad libitum [116K]

Both have an inverse relationship.


Explanation:

The two have an inverse relationship, that is, when elevation increases, atmospheric pressure decreases.

This is due to the amount of air on top of you at your current elevation.

At lower elevations, you have more air above you, and thus more pressure.

At higher elevations, you have less air above you, and thus less pressure.


At high elevation food takes longer time too cook due to low pressure, so at high altitude pressure cooker is used to cook food.


OK, :)

“The genetic code is universal.” This statement means that
Lemur [1.5K]

The correct answer is B

The genetic codes language in all living organisms is the same. This is to say that the molecules of life namely DNA and RNA share the same make up in all living things .

There are five types of nucleotides in nature which are the building blocks of RNA and DNA and these are the same in all living organisms . These nucleotides are Adenine, Thymine, Guanine, Cytosine and Uracil.

According to base pairing rules, in all DNA molecules Adenine will always pair with Thymine while Guanine will always pair with Cytosine.

This  rule is the same with RNA except that here Thymine is replaced with Uracil.  Otherwise the base pairing rule applies in all living organisms, that is to say it is universal.

Question 4....??? What effect can bottleneck events have on population that have nearly become extinct????
ArbitrLikvidat [17]

The answer is; D

It reduces the diversity of the population because some variations in the population can be completely eliminated by the bottleneck effect. Even if the population recovers in population size, the genetic variation will have reduced as compared to the initial population before the bottleneck. For a mall population, this effect can be grave because the reduced genetic variation may mean that the population may be unable to adapt to new selection pressures hence may go extinct.
