Answer:
3.You might think this should mean you need to cut out salt completely, but salt is actually an important nutrient for the human body. Your body uses salt to balance fluids in the blood and maintain healthy blood pressure, and it is also essential for nerve and muscle function.
4.Cooling the mixture is to prevent the DNA from being degraded by the heating.
5.The ethanol pulls water from the DNA molecule so that it then collapses in on itself and precipitates. The DNA will become visible as white mucous strands that can be spooled with the wooden applicator stick.
6.The colder the ethanol is the greater the amount of DNA that is precipitated. (You could try having some of the students use room temperature ethanol and see if the amount of DNA they can spool is the same or less than that for the groups using the ice-cold ethanol.
7.The reason is every strawberry seed contains different genetic material, the product of a myriad of potential gene combinations. Because the genetics of strawberries are so diverse (humans are diploid, strawberries are octoploid)

Explanation:
All organisms must regulate_____ by turning genes on and off different cells at different times. In prokaryotic cells, related genes may be organized into_____, which can be turned on and off as a single unit. Eukaryotes have more complex modes of control, including the packing of chromosomes,____(which can produces several mRNAs from a single gene), and the control of translation. An understanding of gene regulation mechanisms has led to several interesting and important applications. For example, the loss of gene regulation can result in cancer, or out-of-control cell growth. And___can produce new live individuals, while___can produce potentially therapeutic stem cells.
Answer:
All organisms must regulate gene expression by turning genes on and off different cells at different times. In prokaryotic cells, related genes may be organized into operons , which can be turned on and off as a single unit. Eukaryotes have more complex modes of control, including the packing of chromosomes, RNA slicing (which can produces several mRNAs from a single gene), and the control of translation.
An understanding of gene regulation mechanisms has led to several interesting and important applications. For example, the loss of gene regulation can result in cancer, or out-of-control cell growth. And reproductive cloning can produce new live individuals, while therapeutic cloning can produce potentially therapeutic stem cells.
Why is DNA locked in the nucleus of the cell?
Answer:
Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.
Explanation:
Answer:
In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. ... Researchers refer to DNA found in the cell's nucleus as nuclear DNA.
Explain how stem cell therapy helped Lucy break down deoxyadenosine
Answer:
It helped her fight off the stop protein, eventually helping her create more amino acids.
The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.

What are some ways that stars can be different?
Answer:
hello
Explanation:
the star is the far from earth they are big as the not look from the earth .they look twinkel because of atomphere refraction which make the wavelengh of star into the increasing and decreasing wave when increase wave come to our eyes it look bright and when decrease it look dim while plant can not doAnswer:Their brightness is one of the 3 reasons on how you can tell them apart Their brightness is a factor of how much energy they put out–known as luminosity an also how far away they are from earth .Color can also fluctuate from star to star because Not all stars are the same temperature!Some are more cool and some are warmer!Hot stars appear white or blue, rather with cooler stars appear to have orange or red hues.We would normally think a orange or red would mean hot but no in this case!
What are stars made up of?
Stars are made mostly of hydrogen and helium that produce light and heat from the churning nuclear forges inside their cores. All the dots of light we see in the sky are all light-years from Earth!
Solid or gas?
Stars are The first state is a solid and it is the coldest state of matter.
Are stars alive?!
No silly stars are not alive !Their “birth and death.” It's a convenient, if fanciful, way of describing the ultimately ill-fated relationship between matter and energy that is a star.

The location for the SI gene is 3q26.1. What does this information tell you?
The SI gene provides instructions for producing the enzyme sucrase-isomaltase
Annotation 3q26.1. indicates a specific localization of a gene on chromosome number 3.
The localization of a gene in a chromosome is indicated by a specific pattern of bands generated by different cytogenetic staining techniques.The first number/letter used in this code indicates the chromosome (in this case, 3 indicates chromosome number 3).The letter q represents the long arm of the chromosome, whereas the shorter arm is referred to as p (in this case, 3q)The following numbers represent the position of the gene on the chromosome arm, which is evidenced by specific patterns and staining techniques.In conclusion, annotation 3q26.1. indicates a specific localization of a gene on a chromosome.

Explanation:
The table below Anton Leeuwenhoek devised a primitive microscope to observe a sample of his tooth scrapings. How did this help contribute to cell theory?
It helped to show that cells cannot function independently.
It helped to show that some bacteria can swim like fish.
It helped to show that some bacteria are just one cell.
It helped to show that cells can be created from thin air. shows the average wind speeds of four hurricanes in Florida.
Answer:
The correct answer is - option C.
Explanation:
Anton Leeuwenhoek observed the presence of organisms in his tooth scratch or scrapings under the primitive microscope made by himself. At that time there was no knowledge about the bacteria and he named these small creatures as animalcules. These animalcules were bacteria actually.
These creatures were single-cell organisms and able to perform the function as an entity and postulate that bacteria is a single which is a fundamental unit of function and structure of all living organisms.

A track and field coach is trying to decide what beverage is the best pre-training beverage for athletes to drink before a daily training session. The coach has chosen three beverages: a soda, a Gatorade, and water for the athletes to drink before training. The coach will then collect data on their performance during the period of time while training.
Afterward, the coach will track the performance of the athletes over an eight week period to see how their performance has changed.
What is the best Hypothesis for the experiment above? Explain why that is the best Hypothesis.
Answer:
The correct answer is - "which beverage would help athletes the best if he takes it before a daily training session".
Explanation:
The coach is trying to decide which beverage is going to help best for the athletes before their training session. He tried soda, water, and Gatorade and compare the data he gets after his experiment.
According to his experiment, he wanted to find the best beverage that will help athletes best. For this, the best hypothesis would be "which beverage would help athletes the best if he takes it before a daily training session", as it provides the real idea of the experiment.
