D) It is used to break down DNA molecules.
Answer:
used to separate mixtures of DNA, RNA, or proteins according to molecular size
Gel electrophoresis is used for the separation of genetic material present in the cell such as DNA, RNA and even proteins. Thus, the correct option is A.
What is Gel electrophoresis?Gel electrophoresis is a technique which is used to separate the genetic material such as DNA fragments, RNA and proteins on the basis of their size and charge. Gel Electrophoresis involves running an electric current through a gel containing the molecules of interest in it.
The principle of Gel electrophoresis is that the DNA or protein sample to be separated is loaded on to a porous gel placed in an ionic buffer. On the application of electric charge, each of the molecules having different size and charge will move through the gel at different speeds and therefore separates out.
Therefore, the correct option is A.

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.
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.

Which pair of triangles can be proven congruent by SAS?
Answer:
Explanation:
The seconded one
The second triangle can be proven congruent by SAS (side-angle-side). Therefore, option B is correct.
What is SAS property?SAS stands for "Side-Angle-Side" and it is a property of congruent triangles. This property states that if two triangles have two pairs of corresponding sides that are proportional and the included angles between those sides are congruent, then the triangles are congruent.
In other words, if two triangles have the same length of two sides and the angles formed by these sides are the same, then the triangles are congruent.
This property is one of several ways to prove that two triangles are congruent, and it is a useful tool in geometry and trigonometry. The other ways to prove the congruence of triangles are SSS (Side-Side-Side), ASA (Angle-Side-Angle), AAS (Angle-Angle-Side), and HL (Hypotenuse-Leg) properties. Hence, option B is correct.

4.hydrosphere, cryosphere, geosphere
Answer:
When a volcano erupts particles of rock and ash are released into the atmosphere after this water droplets form around?
When a volcano erupts, particles of rock and ash are released into the atmosphere. After this, water droplets form around the rock and ash particles and fall to Earth as rain. The rainwater helps plants grow. Which scenario describes an interaction between two of Earth's spheres?
Explanation:
The spheres of Earth that interact in this scenario are the geosphere, hydrosphere, and biosphere.
The geosphere, which makes up the solid Earth, spews rock and ash particles into the atmosphere during a volcanic eruption. These ascenting particles come into contact with the hydrosphere, or the water systems of Earth. Rain is created when water droplets gather around the particles. This rain, which has been enhanced with minerals from volcanic material, falls to the biosphere and fosters the growth of plants.
The interplay between the geosphere, hydrosphere, and biosphere demonstrates the complex interrelationships between Earth's constituent parts, demonstrating how changes in one sphere can have an effect on others, eventually influencing the environment and sustaining life.

calculate the magnification of the drawing below, If the length of the leaf is 30mm and the length of the drawing made was 100mm
Answer:
10
Explanation:
The magnification of the drawing made was 10 because it had a length of 100mm and originally had a length of 30mm. It can also be said that the magnification is 3 since dividing by the original length (30) we get: 100/30 = 3.

how do i write an email to apply for university
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.

3. Would a cliff in the desert or a cliff along the seashore experience more weathering? Explain your answer.
Answer:
A sea shore would have more weathering, because the gust of wind from the shore line will surley weather out the mountain, including the waves washing out rocks.
Explanation:
Pls give brainliest
A seashore would experience more weathering than the desert. This is because of the gust of wind on the cliff of the mountain.
What is Weathering?
Weathering can be considered as the breaking down or dissolving of rocks and minerals on the Earth's surface. Once a rock or mineral has been broken down by the process called erosion, it transports the small bits of rocks and minerals away from each other. Water, acids, salt, plants, animals, and change in temperature are all the agents of weathering and erosion.
A cliff along the seashore would experience more weathering, because of the gust of wind from the shore line. This will surely weather out the mountains, including the waves washing out the rocks and minerals.
