In which layer of the atmosphere does the aurora borealis form? O A. The troposphere OB. The mesosphere O C. The thermosphere O D. The stratosphere SUBM​

Answers

Answer 1

Answer:

The Thermosphere

Explanation:

Just took the test on A P E X, it's right. Hope this helps :)

Answer 2

Aurora Borealis forms in the thermosphere layer of the atmosphere. Therefore, option "C" is correct.

What are the different layers of the atmosphere?

The atmosphere is made up of different layers which protect the life on Earth and make it habitable. There are four layers of the atmosphere troposphere, stratosphere, mesosphere, and thermosphere.

In the troposphere, the temperature rises from bottom to top.  The ozone layer is present in the stratosphere. This is also known as the flying zone as no clouds are present in this layer. In the mesosphere, the air is much colder as there are gas molecules present that absorb solar radiation whereas the density of molecules in the thermosphere is very low.

The atmospheric layers protect the life on Earth.

A. number of atoms
B. chemical bonds
C. total mass
D. total energy

Answers

Answer:

I think it's chemical bonds I'm not of that helped

The changes occurs in chemical bond during a chemical reaction between two compounds. The correct option is B.

What is chemical bond?

A chemical bond is a long-lasting point of attraction among atoms, ions, or molecules which then allows chemical compounds to form.

Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.

A covalent bond is the strongest bond in chemistry. In such bonding, each atom shares electrons that bind them together.

The bonds that hold molecules together break apart and form new bonds during chemical reactions, rearranging atoms into different substances.

Each bond requires a different amount of energy to break or form; without this energy, the reaction cannot occur, and the reactants remain unchanged.

Thus, the correct option is B.

How big of an advantage does a variant of a gene have to give to start becoming more common in a population?

1. Greater than 0%

2. Greater than 5%

3. Double

Answers

Answer:

The correct answer is 1. Greater than 0%. An allele to become common must have a frequency of at least 0.005%

Explanation:

A polymorphic gene has more than two alleles. The more alleles there are in a population, the more polymorphic the gene is.

In a polymorphic gene, the allelic frequency of the most common allele must be minor of 99%, while the less common allele must have an allelic frequency superior to 0.005%. If any allele does not reach this frequency in the population, it is not considered to be common. In fact, it is considered to be a rare allele.

Explain why the steroid hormone estradiol (MW 272) readily crosses membranes by simple diffusion but the much smaller H requires transport proteins

Answers

Answer:

Estradiol has a higher partition coefficient than H+ ions

Explanation

Estradiol is a non-polar and hydrophobic molecule that has a higher partition coefficient than H+ ions, it means that the cell membrane is more permeable to this molecule because it can dissolve in and diffuse within the hydrophobic phase of the membrane. The movement of polar charged molecules (even small H+ ions) requires the input of energy to be able to dissolve within the lipid bilayer. In consequence, the movement of H+ ions requires proteins capable of transporting these protons through the membrane.

White blood cells called B cells produce proteins that can be used for the treatment of certain illnesses. However, these B cells do not live for very long on their own. To keep the B cells growing for a long time in laboratories, scientists fuse the B cells with cancer cells (fused B-cancer cells) that do grow for a very long time. The particular cancer cells used for the fusion are treated with chemicals that make them unable to produce the nitrogenous bases adenine and guanine, but the B cells with which they are fused do produce these nitrogenous bases. The scientists grow the large fused B-cancer cells in a growth medium that contains necessary nutrients for the cells and includes a source of carbon.
(a) Describe the role of carbon in biological systems.

Proton pump

Cyt C Ribosome

Explanation:

The nucleus of the cell is the largest of all of these structures, all of the others are located inside the nucleus of the cell or interact with it, the nuclear pore is a pore in the nucleus that allows the transport of proteins through the membrane, the proton pump passes through the nuclear pore, and a Ribosome is a protein that transports nutrients, so that would be the smallest.

The order from largest to smallest is nucleous>> >> ribosome >> nuclear pore >> proton pump >> Cyt C.

The nucleus is the organelle that contains the genetic material in a eukaryotic cell, whereas ribosomes are protein factories.

The nuclear pore is a  structure that allows the passage of certain molecules between the cytoplasm and the nucleus.

The proton pump is an integral protein-membrane, whereas Cyt C is a mitochondrial protein.

You are performing an experiment with Primase, using a specific DNA template. In this experiment, you provide NTPs (ATP, UTP, CTP, GTP) which contained only one radioactive phosphate group, in the alpha-phosphate position (the alpha- phosphate is the one attached to the sugar. the other phosphates are beta and gamma). After RNA synthesis occurs, you separate the resultant RNA strand any of the NTPs that have not been incorporated into the RNA, and measure the radioactivity of the newly synthesized RNA.A) In this experiment, would you expect the newly synthesized RNA be radioactive? Explain why.B) If you forgot to add CTP when you did the experiment, would the resulting RNA be radioactive?C) If you did the experiment, with all the NTPs provided, but only the beta phosphate was radioactive for each of the NTPs, would radioactivity be found in the RNA? Explain why.D) If you did the experiment, with all the required NTPs, but only the ATP was radiolabelled Would radioactivity be found in the RNA? Explain why.

Answers

Answer:

(a). Yes.

(b). RNA becomes Radioactive.

(c). No.

(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.

Explanation:

So, let us do right into the explanation behind the answers to the questions asked.

(a). The answer to this part of the question is "Yes" because in creating or in the formation of the glycosidic bond, all the alpha phosphate group were taken into consideration that is they were all used, thus making the newly synthesized RNA to be radioactive.

(b). The RNA becomes Radioactive is the answer to this part of this question because CTP is needed in the experiment.

(c). The answer to this part (c) of this question is ''No'' because the only thing that takes part in bonding is the alpha phosphate.

(d). It depends. If the gamma phosphate and beta phosphate are not labeled, then the RNA will have certain degree of radioactivity.

The diffusion of water molecules a secectively permeable membrane.

What is Diffusion?

The net passive movement of molecules or particles from areas of higher concentration to areas of lower concentration is known as diffusion. There needs to be a concentration gradient for diffusion to happen.

The dissimilarity in the quantity of solutes, particles, or molecules between the two locations will drive them to travel between the two regions.

The gradient created by the uneven particle concentration between two fluids will cause the particles to move in order to balance the discrepancy in concentrations. However, solutes do not migrate in a single direction during the diffusion process.

Therefore, The diffusion of water molecules a selectively permeable membrane.

New Technology Leads to Bigger CitiesIn the 1800s, the Uniodd States was still a very young nation, trying to solidify its identity. The Industrial Revolution began in Great Britain, a fast development ofsociety following the introduction of machines. The United States was slower than Great Britain to fully embrace the changes. Yet key technological developmentscaused a rapid growth in American urban areas.Better farming methods and tools in the 1800s increased food production. Americans were able to grow enough food for their families as well as to sell. Theabundance caused food prices to fall.The expansion of cotton and the growth of textile factories in northern states helped produce the first wave of American industry. More people turned to work innorthern factories as a way to support their families. Thousands of immigrants to the United States also settled in or near port cities, looking for work. Even today,the need for work is a common reason people move to urban areas.As a result, cities grew in numbers of people and physical space. As more people and businesses moved in, they needed buildings for living and working. They needed ways to move around the city. We call this process urbanization,In 1820, the United States had only a few cities of 10,000 residents or more. About seven percent of U.S. residents lived in urban areas. The number of cities withmore than 10,000 people grew quickly over the next 40 years, especially in the Northeast and Midwest. By 1860, about 20 percent lived in cities. Philadelphia andNew York City were the most populated cities in 1860 and would soon reach one million residents.The urbanization of the United States quickened due to technology improvements.
