what type of weather is typically associated with the air pressure system near Salem

Answers

Answer:

According to common weather maps of the region surrounding Salem, Massachusets, the weather typically associated with the air pressure system is rain.

Explanation:

Given the nature of warm air and its tendency to rise, warmer regions tend to fall under the low-pressure system category. These systems, due to the movement of the warm air, have lower pressure at their center than in the areas surrounding them. As the wind blows towards the low-pressure air systems, the cooler and warmer air meet within the atmosphere, which causes the water vapor to condense and form clouds. Oftentimes, these clouds then precipitate, causing rain.

Which side will gain water
What is c ?

Answers

Answer:

1-b

2-b

3-phospholipid bilayer

B side is hypertonic. It will gain water. C is Phospholipid layer.

What is Hypotonic Solution?

A hypotonic solution is a type of solution that has a lower osmotic pressure than any other solution to which it is compared. It is a solution in which a small amount of solute passes across a semipermeable membrane compared to the amount of solute in the other solution.

If the solute concentration outside the cell is lower than inside the cell, these solutes cannot cross the membrane, so the solution is hypotonic to the cell.

The cell membrane consists of a phospholipid bilayer containing embedded proteins present between these two solutions where a hypotonic solution has a relatively low concentration of solutes.

Thus, B side is hypertonic. It will gain water. C is Phospholipid layer.

Compare and contrast light microscopes, scanning electron microscopes, and transmission electron microscopes. Sort each statement into the correct box. some statements may apply to more than one type of microscopes. Some statements may not be used.

Answers

Answer: Light microscope:

use a beam of light to produce magnified images

can be used to examine living cells and tissues

Scanning electron microscope:

use a beam of electrons to produce magnified images

can be used to examine DNA

can be used to examine cells

Transmission electron microscope:

use a beam of electrons to produce magnified images

can be used to examine DNA

can be used to examine cells

Explanation: Light microscope: is a commonly used microscope also known as compound microscope. Magnifies images from 40X upto 1000X. It uses ray of visible light to produce a magnified image. The light microscope can be used to view specimen of both living and dead cells or tissues. However, it doesn't give a detailed view of a specimen like electron microscope.

Scanning electron microscope: It uses electron beam as an illuminating source. It has a much higher resolving power than light microscope because it uses electrons instead of light. It magnifies object upto 500000 times the actual size. Internal structures can also be viewed. However, only dead specimen can be used because the beam of electrons can kill the cells. They are of two types:

1. Scanning electron microscope(SEM): an electron beam passes over the specimen's surface and displaces electrons which are then focused on  a screen to form an image. Images appear in 3-D

2. Transmission electron microscope: electromagnets magnify the image by passing beam of electrons through a thin specimen. Images appear in 2-D

Researchers identify a gene in cockroaches that is responsible for their ability of nerve regeneration. How might it be possible for this gene to be used in treating human paralysis?

Answers

This gene could be analyzed to determine its homology level with a human gene, which then could be restored in its normal expression. This strategy can restore the normal phenotype in defective human cells.

Sequence homology, which refers to the level of evolutionary relationship among genetic or proteins sequences, is a fundamental subject matter to determine gene function.

From this approach (sequence homology search), researchers can identify valuable genes involved in diseases in which the restoration of their normal expression levels can be used to restore the normal phenotype in defective cells.

In this case, the identification of a gene in cockroaches that is responsible for nerve regeneration could be used for subsequent identification of a human homologous gene sequence, which then can be restored in order to treat human paralysis.

how do i write an email to apply for university

Answers

Answer:

Well personally I haven't written an email to apply for a university but i'll try to help.

Composing your Email

1. Find your admissions officer

If possible, locate the email of the admissions officer for your region. For example, if you live in Florida, you want to target the email to the admissions officer that reads for the Southeast. It is important to locate the admissions officer for your region since they will be the person reading your college application when you submit it. They should be familiar with your name and remember you positively.

2. Address the admissions officer properly

Begin your email by addressing the admissions officer in a kind, proper manner. Don’t use slang or abbreviations that you might use with your peers while texting. Your writing should highlight your maturity and ability to communicate in a professional setting.  

“Good morning, Ms. Smith,”

“Hello, Mr. Johnson,”

3. Introduce yourself

Admissions officers receive hundreds of emails a day from prospective students so a concise email that simply gets to the point saves time and energy. Therefore, you shouldn’t spend a great deal of time introducing yourself. You are unlikely to increase your probability of acceptance by sending an email detailing your life’s accomplishments. Instead, write a brief sentence or two, providing your name and any relevant background information that may inform their answer.

“My name is Hayley Hall and I am applying to Pomona College in the Fall of 2020. I am particularly interested in majoring in Engineering.”

4. Be specific

Once you have provided your name and relevant information, ask specific questions. Don’t ask generic questions you should already know the answer to from your college search.

Avoid questions like:

“What’s the acceptance rate for UCLA?”

“What does Yale look for?”

“How much does each credit hour cost for in-state students?”

Colleges provide lots of general information about the school on their website. Search their website thoroughly before reaching out. If you ask for information that the college already provides, it might signal to an admissions officer that you haven’t done your due diligence looking for information on your own.

Instead, ask more detailed questions like:

“What types of companies does the College of Engineering have partnerships with?”

“When do most students start performing research?”  

“What would you say students are most excited about on campus?”

These kinds of questions prove that you have done your research but want more in-depth information about their university. Your curiosity will bode well with an admission officer. It will signal you are seriously considering their university. Their answers will help you make informed decisions about the schools you are considering and potentially provide information for your “Why This College” essay!

5. Do not be afraid to ask questions about your required materials

You can also email admissions officers to confirm they have received all of your materials. For example, if you have sent in your SAT/ACT scores but haven’t received a confirmation email from the school that they received it, you can follow up with the school. The email should be detailed, concise, and professional.

In intramembranous ossification, bone develops directly from sheets of mesenchymal connective tissue. In endochondral ossification, bone develops by replacing hyaline cartilage, bone formation, also called ossification, process by which new bone is produced. ... Soon after the osteoid is laid down, inorganic salts are deposited in it to form the hardened material recognized as mineralized bone. The cartilage cells die out and are replaced by osteoblasts clustered in ossification centres.

Biology which statement applies to cholesterol?
A. It is hydrophobic and found on the outside of the phospholipid biyaler
B. It is hydrophilic and found inside the phospholipid bilayer
C. It impacts membrane fluidity.
D. It is transported in association with glucose in the blood.

Answers

The true statement about cholesterol is that; " It impacts membrane fluidity."

Cholesterol is one of the steroids in the body and serves as a constituent of many hormones. Cholesterol consists of a hydrophilic and a hydrophobic part hence it is able to interact both with aqueous and nonpolar environments.

Cholesterol impacts membrane fluidity in the sense that it regulates the direction of membrane fluidity. At high temperatures, cholesterol raises the membrane temperature whereas at high temperatures, it intercalates between phospholipids thereby preventing stiffening.

If each of these food chains start with 10,000 grams of phytoplankton, how much reaches the highest trophic level in each food chain

Answers

Energy is transferred from one trophic level in a food chain to another. However, not all the energy available at a trophic level is transferred to the next.

Only about 10% of the energy in the lower trophic level gets to the immediate higher trophic level and the rest is lost as metabolic heat.

Thus, if a food chain starts with 10,000 grams of phytoplankton, the quantity that will get to the highest trophic level would depend on the number of intermediate trophic levels in between the lowest and the highest.

For every step the energy is transferred up the trophic level in the food chain, 90% of it is lost.
