Which planet do most known extrasolar planets least resemble ?

Shure_mikrofon_55S

Answer :

Most of them are Jupiter-like. Some are so close to their star they orbit in just a few day, some are further away.

The 2 main methods of extra-solar planet detection are by measuring a transit, or the stars “wobble”. With the transit, we look at a star a carefully and precisely measure its intensity, if the planet moves in front of the that star, it blocks some of the light, thus decreasing its intensity. we can measure that, and even watch it happen on occasion (the fast orbiting planets).

The wobble method, is built around the fact that a Star and a planet orbit around their COMMON center of mass, not the center of the star. If the planet is big enough it can move this common center far enough from the star center to give the star a wobble like appearance to us as the Jupiter size planet tugs it around.

How is the sickle cell allele maintained through natural selection ?

Answer :

Heterozygous individuals pass the dominant and recessive alleles to offspring. The heterozygous condition confers some resitance to malaria, especially in children. So, those who possed this condition would tend to survive more often in malaria country and live to have more children, some of which would inherit the trait.

Importance of hydra ?

Answer :

Researchers from Kiel (Germany) have examined why the polyp Hydra is immortal — and unexpectedly discovered a link to aging in humans.
Human longevity gene discovered in Hydra

“Surprisingly, our search for the gene that causes Hydra to be immortal led us to the so-called FoxO gene,” says Anna-Marei Böhm, PhD student and first author of the study. The FoxO gene exists in all animals and humans and has been known for years. However, until now it was not known why human stem cells become fewer and inactive with increasing age, which biochemical mechanisms are involved and if FoxO played a role in aging. In order to find the gene, the research group isolated Hydra’s stem cells and then screened all of their genes.

Pros and cons of finger tattoos ?

Answer :

Pros: You obviously want it, it’s your body so you can do what you want with it, infection is unlikely if you get it done professionally, they’re quite easy to show off as and when you want and can be hidden in some situations if needs be.

Cons: It will fade quite quickly as the skin on your hand renews regularly and, since you use your hands a lot, it may fade quicker than on the back of your hand. It probably won’t disappear but may blur and the ink will not be as vibrant for long, The tattoo will also probably be small and most tattoo shops have a minimum price, even for small tattoos. Therefore you may have to spend a considerable amount of money for a small tattoo. As the skin is quite thin, this is quite a painful place to get a tattoo. Also, be aware that hand tattoos may be difficult to hide in a workplace setting.

Classify each situation by the equation that would quantify it ?

Answer :

A. A container of ammonia cleaner is stored in the janitor’s closet off a lecture hall after being used at night for cleaning. The container has a very small hole in the lid. The next morning the entire lecture hall smells of ammonia. How would you calculate the speed of the ammonia molecules as they move out into the lecture hall?

B. The pressure on a tire pump is read. The handle of the pump is pushed down as far as possible. The reading of the pressure on the gauge is taken again. How would you calculate the final pressure?

C. The burner under a hot air balloon is ignited and the balloon expands. How would you calculate the expanded volume of the balloon?

D. A front-end collision causes the air bag in an automobile to deploy by the reaction of sodium azide to produce nitrogen gas. How would you calculate how much sodium azide is needed to fill a standard size bag with nitrogen under STP conditions?

E. Aerosol cans have a label that warns the user not to use them above a certain temperature and not to dispose of them by incineration. Even an empty can contains residual gaseous propellant.

If the residual pressure in the can is 1.31 atm when it is sitting on a shelf near a furnace, how could you calculate the pressure when the can is placed on top of the furnace where the temperature reaches the boiling point of water?

F. In an automobile engine, at the end of the upstroke the piston is at its maximum height in a cylinder of exact dimensions. At this time, a precisely measured mixture of fuel and oxidant ignites to form gaseous products. If the ignition temperature is known, how could you calculate the pressure inside the cylinder just before the piston moves downward?

Match with appropriate answers.

1. P1V1=P2V2
2. U=square root:(3RT/m)
3. (T1/V1)=(T2/V2)
Others
4. (P1/T1)=(P2/V2)

Answer :
A = 1
B = 1
C = 3
D = PV=nRT
E, F = 4

Which two particles in an atom are equal in number ?

Answer :

Protons and electrons.

How are tone and the meaning of words related ?

Answer :

Which of the following is a definition of ethic ?

Answer :

First, ethics refers to well-founded standards of right and wrong that prescribe what humans ought to do, usually in terms of rights, obligations, benefits to society, fairness, or specific virtues. Ethics, for example, refers to those standards that impose the reasonable obligations to refrain from rape, stealing, murder, assault, slander, and fraud. Ethical standards also include those that enjoin virtues of honesty, compassion, and loyalty. And, ethical standards include standards relating to rights, such as the right to life, the right to freedom from injury, and the right to privacy. Such standards are adequate standards of ethics because they are supported by consistent and well-founded reasons.

Secondly, ethics refers to the study and development of one’s ethical standards. As mentioned above, feelings, laws, and social norms can deviate from what is ethical. So it is necessary to constantly examine one’s standards to ensure that they are reasonable and well-founded. Ethics also means, then, the continuous effort of studying our own moral beliefs and our moral conduct, and striving to ensure that we, and the institutions we help to shape, live up to standards that are reasonable and solidly-based.

d. They were all from poor families.

Answer :

c. They were all from the same town.

The Civil War soldier’s home away from home was his regiment. Regiments were often composed of men who had lived in the same neighborhoods and had known each other before the war. In some cases, regiments had a distinctive regional or ethnic character—Irish, German, Italian, Jewish, Indian, or black, among others. In some cases, such as the Zouaves, regiments were distinguished by their vivid uniforms.

Trace lineage of nco back to ?

Answer :

Trace lineage of nco (noncommissioned officer) back to?

The history of the United States Army and of the noncommissioned officer began in 1775 with the birth of the Continental Army . The American noncommissioned officer did not copy the British. He, like the American Army itself, blended traditions of the French, British and Prussian armies into a uniquely American institution. As the years progressed, the American political system, with its disdain for the aristocracy, social attitudes and the vast westward expanses, further removed the US Army noncommissioned officer from his European counterparts and created a truly American noncommissioned officer.

Bohr’s theory of the hydrogen atom assumed that ?

1. the electron can exist in any one of a set of discrete states (energy levels) and can move from one to another by emitting or absorbing radiation.
2. electromagnetic radiation is given off when the electrons move in an orbit around the nucleus.
3. energy, in the form of radiation, must be continually supplied to keep the electron moving in its orbit.
4. the electron in a hydrogen atom can jump from one energy level to another without gain or loss of energy.
5. because a hydrogen atom has only one electron, the emission spectrum of hydrogen should consist of only one line.

Answer :

1. the electron can exist in any one of a set of discrete states (energy levels) and can move from one to another by emitting or absorbing radiation.
The first one almost works but hydrogen can be excited to 2 other different energy levels from ground state and so emit different wavelengths of red when jumping orbits.
It may be option 1 because its tendency of any element to achieve stability by losing energy and practically after losing 1 electron hydrogen atom becomes positive ion.
