Explain what friction, corollas, and a low pressure gradient does to an air parcel. IF YOU CAN PLEASE GIVE A SHORT ANSWER.

Answers

Answer:

sorry big answer Answer with Explanation:

Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.

Air parcel - refers to a body of air that is "imaginary."

Pressure gradient - the change in pressure across a given distance.

Pressure gradient force - the net force that is being directed from high pressure to low pressure.

When an air parcel is at rest, the pressure gradient force acts upon it. It will then move from high pressure to low pressure.

However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.

Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."

When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.

este fenómeno?

Answers

La troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

En la capa de la troposfera, que es la capa más baja de la atmósfera, hay vapor de agua, dióxido de carbono, metano y algunos otros gases que son responsables de la absorción de la radiación infrarroja. Parte de la radiación infrarroja se escapa al espacio, pero una parte es detenida y absorbida por los gases de efecto invernadero presentes en la atmósfera.

Esta absorción de radiación infrarroja por los gases de efecto invernadero contribuye a un aumento de la temperatura de la superficie de la tierra y de la atmósfera. Entonces, podemos concluir que la troposfera es la capa de la atmósfera donde una parte de la radiación infrarroja es absorbida por los gases de efecto invernadero.

Answers

Answer: This picture has the answer

Explanation:

The nucleotides which are found in the DNA molecule are made up of nucleoside moieties and phosphate molecule. These are of five types which include adenosine, guanosine, uracil, thymine, and cytosine.

What is a nucleotide?

Nucleotides are the organic molecules which consist of a nucleoside and a phosphate moiety. The nucleotide molecules serve as the monomeric units of the nucleic acid polymers such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all life forms on the Earth.

A nucleotide is one of the main structural components, or the building blocks, of DNA and RNA molecules. A nucleotide consists of a base which has one of four nitrogenous base which could be purine and pyrimidine such as adenine, thymine, guanine, and cytosine plus a molecule of sugar and one molecule of phosphoric acid.

the genes stc1 and stc2, which share a common ancestor, are found in both zebrafish and humans. all four stc genes display similar patterns of exon and intron sequences. based on these facts, what is the most likely explanation for the origin of stc genes?

Answers

Based on these facts, we can state that the genes of the two organisms had a eukaryotic origin.

We can arrive at this answer because:

Despite having exons, prokaryotes do not have introns in their genomes.This means that if two organisms have the same sequence of introns and exons, they have a common ancestor, in addition to having their genes originated in a eukaryotic organism, which explains the sequence of introns.

This means that the genetic expression of these two organisms has similarities, even if they are organisms with different biological processes.

What is one reason that the surface water at the equator is less dense than

Answers

Answer: At low latitudes, near the equator, direct overhead sunlight received all year warms surface waters.

Cold water is also more dense, and as a result heavier, than warm water. Colder water sinks below the warm water at the surface, which contributes to the coldness of the deep ocean.

1) conduct translation differently
2) contain different DNA
3) contain different chromosome
4) transcribe many different genes
5) conduct replication differently
6) have different transcription factors
7) contain different genes

Answers

Given our understanding of the mechanisms behind genetic expression, we can confirm that when comparing skin cells to kidney cells, the only correct option is option 4 which states that the cells "transcribe many different genes".

The human genome encodes for every gene in the human body. This genome sequence is stored in the chromosomes of cells. These chromosomes are identical for every single cell in the human body. Therefore, every cell contains the same DNA, genes, and transcription factors in its chromosomes.

What allows each cell type in the human body the ability to differentiate from one another and complete vastly different functions is the way in which these genes are expressed. Though every cell contains the entire genetic code, only some genes for each cell are transcribed, which results in a different combination of proteins in each cell and leads to the difference between skin and kidney cells (as just one of many examples).

It is an autosomal recessive disorder.

The chances where the two two individuals having a child with Tay-Sachs if both individuals are not of Ashkenazi or Franch-Canadian descent is 25 % that is the child will not have any disease.

The chance where  the child inherits a mutated one  from one parent and becomes a carrier, but will not have  the condition themselves. 1 in 4 (25%) chance that means  the child inherits a faulty gene from both parents and develops Tay-Sachs disease.

In the original game, it was virtually impossible to get through to Level 22 before Mario was killed by the game. This was an unintended consequence of how the number of bonus points was calculated and stored.The number of bonus points a player starts with when they move onto a new level depends on the number of the level that they are moving onto. Behind the scenes, Donkey Kong takes the level that is about to be entered, multiplies it by 10 and adds 40, thus yielding the first two digits of the players starting bonus.So, for example, if a player is about to start Level 2, the bonus number is calculated like this:2 10 + 40 = 60.This bonus number is stored in a single byte as an unsigned integer. The bonus number will never be 0. i.Write down and evaluate an expression for the number of different unsigned integers that can be represented in a single byte. Then write down the largest unsigned integer that can be represented if no representation for 0 is required. ii.Find the bonus number associated with Level 22.
