How/why does the DNA separate? Discuss porosity
or pores, electricity, DNA's charge & size of DNA
pieces. Highlight each term.
Answer:
Gel electrophoresis is a technique used to separate DNA fragments (or other macromolecules, such as RNA and proteins) based on their size and charge. Electrophoresis involves running a current through a gel containing the molecules of interest. Based on their size and charge, the molecules will travel through the gel in different directions or at different speeds, allowing them to be separated from one another.
All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only. Using electrophoresis, we can see how many different DNA fragments are present in a sample and how large they are relative to one another. We can also determine the absolute size of a piece of DNA by examining it next to a standard "yardstick" made up of DNA fragments of known sizes.
What is a gel?
As the name suggests, gel electrophoresis involves a gel: a slab of Jello-like material. Gels for DNA separation are often made out of a polysaccharide called agarose, which comes as dry, powdered flakes. When the agarose is heated in a buffer (water with some salts in it) and allowed to cool, it will form a solid, slightly squishy gel. At the molecular level, the gel is a matrix of agarose molecules that are held together by hydrogen bonds and form tiny pores.
At one end, the gel has pocket-like indentations called wells, which are where the DNA samples will be placed:
Before the DNA samples are added, the gel must be placed in a gel box. One end of the box is hooked to a positive electrode, while the other end is hooked to a negative electrode. The main body of the box, where the gel is placed, is filled with a salt-containing buffer solution that can conduct current. Although you may not be able to see in the image above (thanks to my amazing artistic skills), the buffer fills the gel box to a level where it just barely covers the gel.
The end of the gel with the wells is positioned towards the negative electrode. The end without wells (towards which the DNA fragments will migrate) is positioned towards the positive electrode.
How do DNA fragments move through the gel?
Once the gel is in the box, each of the DNA samples we want to examine (for instance, each PCR reaction or each restriction-digested plasmid) is carefully transferred into one of the wells. One well is reserved for a DNA ladder, a standard reference that contains DNA fragments of known lengths. Commercial DNA ladders come in different size ranges, so we would want to pick one with good "coverage" of the size range of our expected fragments.
Next, the power to the gel box is turned on, and current begins to flow through the gel. The DNA molecules have a negative charge because of the phosphate groups in their sugar-phosphate backbone, so they start moving through the matrix of the gel towards the positive pole. When the power is turned on and current is passing through the gel, the gel is said to be running. [What voltage is used to run a gel?]
DNA samples are loaded into wells at negative electrode end of gel.
Power is turned on and DNA fragments migrate through gel (towards the positive electrode).
After the gel has run, the fragments are separated by size. The largest fragments are near the top of the gel (negative electrode, where they began), and the smallest fragments are near the bottom (positive electrode).
DNA samples are loaded into wells at negative electrode end of gel.
Power is turned on and DNA fragments migrate through gel (towards the positive electrode).
After the gel has run, the fragments are separated by size. The largest fragments are near the top of the gel (negative electrode, where they began), and the smallest fragments are near the bottom (positive electrode).
Based on similar diagram in Reece et al.^2
2
squared
As the gel runs, shorter pieces of DNA will travel through the pores of the gel matrix faster than longer ones. After the gel has run for awhile, the shortest pieces of DNA will be close to the positive end of the gel, while the longest pieces of DNA will remain near the wells. Very short pieces of DNA may have run right off the end of the gel if we left it on for too long (something I've most definitely been guilty of!).
Visualizing the DNA fragments
Once the fragments have been separated, we can examine the gel and see what sizes of bands are found on it. When a gel is stained with a DNA-binding dye and placed under UV light, the DNA fragments will glow, allowing us to see the DNA present at different locations along the length of the gel.

Do the same thing with your second piece of evidence. Write a third paragraph, using stating your evidence, using facts and details from the story, and a quote from the story to prove your explanation.
Answer:
“I don’t see the money . . . and I bet I never shall.” Herbert’s suggestive wish foreshadowed Herbert was going to die, thus creating suspense because the readers would want to know when this event would occur or how. It’s ironic because the reader didn’t expect him to wish for his own death by accident. It also creates suspense for the readers because they want to know what will happen next, how will they deal with the fact their son died in such a horrific way by merely wishing for money.

When we lose an organism to extinction, we are no longer able to study it.
What kind of discoveries may we miss out on if an organism goes extinct?
How might the crisis in biodiversity lead to a food crisis for humans?
Answer:
there is a high chance that we may miss out on the evolution of the specimen.
Explanation:
I don't know the second one
Answer:
Hello there,thanks for using brainly! (To whoever keeps camping in my profile stop reporting and deleting my answers its getting annoying)
Explanation:
Answer to number one: When we lose an organism to extinction we loose the chance to be able to study it more thoroughly, see an evolution of the species, identify which animal,insect,etc family it came from, and see what it was capable of doing when it was alive (an example of this was learning that pterodactyls were capable of flying)
Answer to number two:The crisis of biodiversity will lead to a food crisis for humans because:
1.No varieties in certain foods like plants and animals that are healthy
2.The Less food there is,more animals go extinct which means humans will go extinct too.
and finally 3: Without certain types of species like the bee, humans have no chance of survival (since bees pollinate flowers,fruits,and plants which could be used for human consumption and medicine)

essay about circulatory system
Answer:
The circulatory system is one of the most important systems in the human body. It consists of the heart and blood vessels. It is what makes the blood in our body go round. The blood carries oxygen, nutrients and hormones and takes them to where they are needed and removes the waste products like carbon dioxide.
The circulatory system nourishes every cell, tissue, organ and organ system in the body. There are approximately ten pints of blood constantly circulating through seventy- five- thousand miles of blood vessels. These blood vessels reach every cell in the human body. Once they reach the cells they deliver much needed oxygen and remove carbon dioxide and other…show more content…
Arteries have walls that are much more elastic than veins because they transport under high pressure. The arteries cause you to feel a pulse in your wrist because of the great force of the heart pumping new blood into them. All the blood in the arteries, except for the pulmonary arteries, is oxygenated. The arteries divide up into smaller vessels called arterioles so have more muscle fibres and less elastic tissue than the larger arteries which allows them to contract and make the vessels narrower to restrict the blood flow. The arterioles divide up even more to form a branching network of vessels passing between the cells of every living tissue. The final branches are the capillaries.

One unfortunate side effect of these price ceilings is that they will likely lead to a shortage as prices are kept from rising to their equilibrium level.
A price ceiling is a form of price control where the government sets the maximum price of a product. The price of the good is usually set below equilibrium price.
Effects of a price ceiling
It leads to shortages. This is because the profit that can be earned by producers has fallen and this discourages the supply of goods and services. It leads to the development of black markets. Consumer surplus increases. This is because price is below equilibrium price.

What does Canada and climate change have to do together:
4-5 sentences
Answer:
Over the years with increasing temperatures from centuries Canada's weather temps has increased highly. You see, Canada has always been a country with low temperatures. With global warming and carbon dioxide being reused for decades causes build-up in the atmosphere and since that reused carbon has been through the layers (of the atmosphere) it releases higher tempratures. Carbon can reach the thermosphere. But you may be wondering why Canada is still a cold place if the thermosphere is the hottest layer. That's because CO2 is the primary gas that radiationally cools the thermosphere, but at solar maximum, increases in other minor gases cause CO2 cooling to be less important. The "build-up" in the atmosphere gets released because that's how we are still alive.

Explanation:
The amount of slang i use on a daily basis can range from medium amounts to larger amounts depending on how im feeling that day and typically I use a variety of slang every day, I like to use slang as a way to shorten the words and also to talk to friends in a funnier manner.
And yes infact the slang i use depends on if im with friends or other people i might switch up what im saying to sound more proper or to just joke around with my homies.
My favorite slang words include, Bussin, Sheesh, Homies, and I know its weird but sussy baka. I think it adds color to what im saying or just makes it a lot funnier. Because Bussin just means good but it sounds funnier than saying this is good because you are saying this is bussin.
I use more of the popular slang so i feel it might be popular for a few years and than die down just like the dab or any other popular moves that people did in like 2018-
In fact i do use the urban dictionary sometimes for the laughs and i do look up slang on there and i can find the definition but no i havent really posted anything onto the urban dictionary or voted for any :)

The true statement about the part of the poem has Harriet Tubman. The movie "Harriet Tubman" is a significant and effective tool to keep in mind the challenges that Black people in Tubman's day experienced.
The poem employs straightforward and easy-to-understand language. There are no instances of terms, phrases, or concepts that a wide range of readers wouldn't be able to understand.
Eloise Greenfield's "Harriet Tubman" provides a thoughtful account of Tubman's life and accomplishments.
The opening line of the poem is devoted to the poet's description of how Tubman realized she wasn't intended to be a slave and that she wasn't going to stay one. She bid her friends farewell and fled, taking nothing with her.
Therefore, Harriet Tubman appears in the poem in a truthful statement.
