When writing a scientific paper, look for the most credible sources. Science doesn’t show bias, but we humans tend to show bias. Beware of sites and articles that provide facts without proper scientific evidence. Avoid using information from such sites. You must be able to identify reliable sites so the data in your paper is credible.

Use sources that end in .gov (government sites), such as CDC.gov. They are reliable sources. You can also use sites ending in .edu. They can be deemed trustworthy, but sometimes the information is written by students rather than scientists. Always find out who the author of the article is before proceeding. Some .org and .com sites are credible, but you need to analyze the content to verify their authenticity. As you review a source, try to answer these questions:

Who authored the article?
Is this person a scientific expert in the species I’m researching?
What is the purpose of the article?
Does the article state facts that scientists can prove with evidence?
Are there opinions in the article?
How old is the article?
Do other credible sources support the statements in this article?

Explanation:

Cancer is the name given to a collection of related diseases. Cancer is more than one type of disease. In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation. CAD, Stroke, Respiratory illness, COPD are all diseases related to cancer. Inherited genetic mutations play a major role in about 5 to 10 percent of all cancers. There are many environmental pathogenic factors that can cause cancer. For example , Tar and Coal-Tar Pitch , Emissions , Secondhand Tobacco Smoke (Environmental Tobacco Smoke) , Arsenic , Soot , Asbestos , Wood Dust. When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system. Cancer is hard to treat in later stages because it probably has already spread through out the body. The grade of a cancer depends on what the cells look like under a microscope. In general, a lower grade indicates a slower-growing cancer and a higher grade indicates a faster-growing one. Some examples of cancer treatments of cancer are, Surgery, Chemotherapy, Radiotherapy, Cancer drugs, Hormone therapy, Stem cell and bone marrow transplants, Targeted cancer drugs. A new treatment involving a photosensitising agent that makes cells more sensitive to light and, by doing so, causes cancer cells to be destroyed when a laser light is directed on a cancerous area. One challenge is, druggable genomic alterations are diverse and represent only small subsets of patients in certain tumor types, which limits testing their clinical impact in biomarker-driven clinical trials. Next-generation sequencing technologies are increasingly being implemented for molecular prescreening in clinical research, but issues regarding clinical interpretation of large genomic data make their wide clinical use difficult.

What would be different on Earth if the Moon did not exist?

Answers

The moon influences life as we know it on Earth. It influences our oceans, weather, and the hours in our days. Without the moon, tides would fall, nights would be darker, seasons would change, and the length of our days would alter.
1.) There would be an effect on the tides. For example El Niño and La Niña are lunar tidal phenomenon that is partially caused by the moon. Tides would be nearly 2/3 shorter.
2.) The earth would rotate about 3 times faster.
3.) With no moon, the tilt of the Earth’s axis which would cause a large shift in seasons and weather.
4.) There would be no lunar eclipses.
5.) The moon provides a lot of light at night, so if there was no moon, the nights would be extremely dark.
6.) Days would also be much shorter.

Answers

1: Equilibrium

[] When two forces are equal in opposite directions, they are in a state of equilibrium

2: Friction

[] It can be hard to sometimes slide a paper across a table, roll a car across the ground, etc etc. This is because of a force called friction which resists motion

3: Displacement

[] Work is only "done" when the object or surroundings are having movement, or in motion, and this creates displacement

4: Force

[] A force is a push/pull in any direction, this is a simple definition so not much can be added.

5: Inertia

[] Inertia is a force that likes to remain unchanged, or without movement

6: Effort

[] "Meg is holding up weight without movement. She hasn't done any work since it did not move, but is tired. Why?" Effort! She still put in effort even though no "work" happened

7: Work

[] Force times displacement is the equation for work

8: Motion

[] Look back to #3, when there is motion we can tell work is done

Thus, Since the turn of the 20th century, glass has been made with calcium fluoride, a novel substance. It is a solid that dissolves readily in water and has a special physical and chemical makeup that makes it suitable for usage as a glassmaking material.

Glass used in windows, bottles, and other glass goods was formerly created from calcium silicates before the invention of this substance. The new glass, referred to as glass with added fluorides, has a number of advantages over calcium silicates, which have drawbacks that make them unsuitable for the creation of modern glass.

Answers

The sound of a flute is poetic, light, mellow, and soft. Flute is a woodwind musical instrument produces the mild sound.

How flute produces sound?

Sound is a vibration that propagates as an acoustic wave, through a transmission medium such as solid, liquid ang gases. When an object vibrates, it causes a movement in surrounding air molecules. The molecules collide with the molecules close to them, causing them to vibrating as well.

The sound from flute comes due to the vibrating columns of air inside it. In a flute, the air gets vibrated and the resonator amplifies the vibration and gets modified into sound. When air is blown into the holes of flute, it creates the vibration in the air molecules inside the flute and hence, sound is produced.

The flute can produced continuous sound by the presence of number of holes in it. The flute sounds may be high pitch or soft tone depends on the position of upper and lower lips on flute.The sounds of flute are rich, gentle and gracefull.
