A scientist carried out an experiment to follow the movement of carbon atoms within animal cells. To do this, the scientist added glucose with radioactively labeled carbon atoms to a culture of cells growing in a Petri dish.

After a certain amount of time had passed, the scientist tested parts of cells for radioactivity. Radioactivity was detected in various biomolecules, including DNA.


Which of the following statements best explains why radioactivity was detected in the DNA?
Choose 1 answer:

(Choice A)
The DNA was in close proximity to the radioactive glucose during its formation.

(Choice B)
Carbon atoms that were once in the radioactively labeled glucose were used to form DNA.

(Choice C)
The DNA was made up of radioactively labeled glucose subunits.

Answers

Answer 1

Carbon atoms that were once in the radioactively labeled glucose were used to form DNA -  this statement best explains why radioactivity was detected in the DNA.

What is radioactivity in DNA?

Radioactivity is known to induce tumors, chromosome lesions, and minisatellite length mutations.

Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coil around each other to form a double helix carrying genetic instructions.

The radiation could damage the cell’s DNA, but the DNA repairs itself. The radiation could prevent the DNA from replicating correctly. The radiation could damage the DNA so badly that the cell dies.

The correct answer is option B.

why are there earthquakes​

Answers

Answer:

Earthquakes are usually caused when underground rock suddenly breaks and there is rapid motion along a fault. This sudden release of energy causes the seismic waves that make the ground shake. The earthquake starts at the focus, with slip continuing along the fault. The earthquake is over when the fault stops moving.

Causes of Earthquakes in General

- Induced Earthquakes. Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
- Volcanic Earthquakes. Volcanic quakes are associated with active volcanism.

From when we are very little, we are taught to know the difference between right and wrong and how to follow rules. As we get older, rather than the rules that we followed as children, we learn to follow laws that allow us to function as adults in today’s society.

We are all probably familiar with traffic laws or laws about stealing or committing crimes, but did you know that there are laws and public policies written specifically for and about families?

If you didn’t already know about these particular laws, now is your chance to find out!

For this activity, you will be researching the various laws and public policies related to families. In addition, you will be creating several scenarios where these laws might come into play.

Activity Guidelines:
You will start by researching various laws and public policies that pertain to families. You can really take this research in any direction that you like, while keeping in mind that the ultimate goal will be to write five short scenarios and connecting each one to a different family law or policy. For example, you could write a scenario that involves a parent who is intentionally hurting their child and connect this scenario to a child abuse law.

Each scenario description should be no more than about one paragraph in length. You are welcome to include dialogue in your scenario or simply summarize and explain your scenario idea. After each scenario, you will write the specific family law or policy being broken in the scenario or how it otherwise pertains to the scenario. The name of the law or policy and a brief explanation of its connection to the scenario is all that you need to include.
WILL MARK BRAINLY-IST
A basic template is included below. Feel free to use it or create your own in a word processing or slideshow program.

Your grade will be based on creating all five scenarios and your ability to connect each one to a different family law or policy. For further details on how you will be graded, see the rubric below.

Explanation:

The Maine Department of Transportation (DOT) has a fleet of roughly 400 plow trucks that are used to control snow and ice on
approximately 8300 lane miles of Maine's state roads. They usually plan on an average of about 30 treatable events in a winter. This
includes the use of rock salt, salt brine and winter sand, a mix of sand and salt. Salt brine is used on roads and bridges prior to a
storm to delay ice and snow from sticking to the roadway and is also used in plowing to fight the buildup of ice and snow throughout
the storm. Rock salt helps keep roads safe when winter storms hit, reducing winter road accidents, but it can also have negative
effects on plant life and aquatic ecosystems. What is something your community can try to reduce the environmental impact of
salting? Select ALL that apply.
A)
Buy more snow plows and use less salt.
B)
Ban all salt based solutions in the state.
C)

Explanation:

2.After entering the bloodstream, the hematopoietic stem cells travel to the bone marrow. There, they begin to produce new white blood cells, red blood cells, and platelets in a process known as engraftment.

3.Red blood cells are an important element of blood. Their job is to transport oxygen to the body's tissues in exchange for carbon dioxide, which they carry to the lungs to be expelled. Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts.

"Women who have served in the Palace, but who later get married and live at home, are called Madam and receive the most respectful treatment. To be sure, people often consider that these women, who have displayed their faces to all and sundry during their years at Court, are lacking in feminine grace. How proud they must be, nevertheless, when they are styled Assistant Attendants, or summoned to the Palace for occasional duty, or ordered to serve as Imperial envoys during the Kamo Festival! Even those who stay at home lose nothing by having served at Court. In fact they make very good wives. For example, if they are married to a provincial governor and their daughter is chosen to take part in the Gosechi dances, they do not have to disgrace themselves by acting like provincials and asking other people about procedure. They themselves are well versed in the formalities, which is just as it should be. What conclusion can be drawn about the authors point of view in this passage? Women who serve in the court are not graceful. Serving in the palace benefits women later in life. Serving in the palace should be the goal for all women. Women who get married later in life receive the most respect. 10. John is mixing paint.He uses black, green and blue in the ratio 6:3: 1.
