Science Experiments

yes it can
depends how much covering the egg has if the egg has 1 layer of paper it wont protect it. But if the egg is covered by play doe it will protect it. There will be a crack or a scratch.

Myelin is the material that covers the spinal cord. It protects the cord from damage. If the myelin wears away, then a person is said to have Multiple Sclerosis.

the newton's rings are formed due to the phenomenon of thin film interference.

here, the condition for constructive interference(the ring appearing bright) is that the optical path difference between interfering waves should be an integral multiple of the wavelength.

the optical path difference is given by 2t-(l/2) if t is the thickness of the air film at that point and l is the wavelength of light.

at the central point, the lens touches the surface so thickness t=0. thus the optical path difference is simply l/2, which is the condition for destructive interference, not constuctive interference.

so the central spot has to always be dark.

They use a variety of tools such as a highly complex microscope, telescope or something as simple as a ruler and piece of string, the tools depend entirely on the experiment.

Sort of. First off rubbing alcohol doesn't have to be all alcohol, it can be some water in it too, and water can promote rust. Next thing rubbing alcohol can remove a possibly protective layer of grease, which can make metal rust faster.

A salad is a mixture because you can take it apart. Even water and salt can be taken apart so its a mixture. A mixture is when two things have been put together and both chemical properties are still there. Where as wood and fire, the fire and wood turn into ash and some gases. So its not a mixture its a chemical reaction.

There are some exceptions to this. Some mixtures, (like chemical mixtures) when put together form a new chemical and you are not able to separate them again.

So think of a mixture as two things being put together.

The answer is an allele. I hope your not cheating on a fill-in-the blank biology worksheet. ;) It's alright. That's why I changed this because it said, "Your mom". That's not the right answer.

Molecular formula of Hypo solution. & laboratory prepration method of the hypo solution?

Newton is a measure of force, Joule is a measure of work done. Newton refers to the mechanical energy of moving matter, while joule refers to any form of energy possessed by matter.

E.g. W = f X d where W is work in joules, f is force in newtons, and d is distance in meters.

Objects that allow light to pass through but that are not clear.

For example: A x-ray because you can bones, it's see through.

The purpose of the experiment was to discover how the type of bread affected the amount of mold. The bread was cut and placed in separate Ziploc bags. The bread was measured for mold every day and was recorded on the data sheet. My hypothesis was "If the white, wheat, whole wheat, sourdough, and sweet bread were placed in Ziploc bags and left for 20 days, then the sweet bread would grow the most mold because the sweet bread had the most energy (sugar) that the mold can use to grow." Whole Wheat bread was the type of bread that grew the most mold, while white, wheat, and sourdough did not grow any mold. When Whole Wheat bread was left to mold, it grew an average of 60.91 square cm. When sweet bread was left to mold, it grew an average of .58 square cm. of mold. When white, wheat, and sourdough were left to mold, they grew no visible mold.

A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.

microscopic analysis of mouth cells: a closer look at bacterial growth and colonies...hope this helps( it probs will)

causation

Milgram's experiment showed a number of things. The initial experiment involved participants being asked to give apparently harmful and potentially lethal electric shocks to a stooge (who they thought was simply a participant) upon the stooge's incorrect answers. It was estimated by Psychiatrists that most people would drop out early on and refuse to keep on giving shocks, and that nobody would go all the way to 400 volts. In actuality, everyone sent severe and dangerous shocks of 300 volts, and most went all the way.

This shows that people are generally willing to obey an authority figure, even when it might lead to harming or even killing another person.

Milgram also did a number of variations on his experiment, with it taking place in an old office block, with the experimenter phoning through instructions, with other stooges acting as support, or refusing to continue the experiment, and so on.

These variations showed that people are less likely to obey if their victim is closer, if the setting doesn't suggest legitimate authority, if the experimenter is not nearby, or if other participants are refusing to obey. They also showed that someone is much more likely to obey if the participant believes someone else is sending the shocks, not them.

Myelin is a fatty substance that insulates and protects spinal nerve cells, and allows for faster signal transmission. Therefore as myelin increases in children, their coordination improves.

The live R bacteria had acquired polysaccharide capsule.

Liquid-Plumr is a highly alkaline product that contains 0.5-2% sodium hydroxide and 5-10% sodium hypochlorite. The pH in the original answer is for an acidic product. The correct pH is about 13.

Sugar crystals grow faster in tap water because there are more chemicals in tap water.

In short, a hypothesis is a statement believed to be true - because of observation or reasoning, for example - but one not yet tested by experiment, or, in mathematics, not formally proven to be true. Hypotheses in science are often predictive, and their predictions can form the basis of experiments to prove or refute them.
That really captuers the spirit of it. Thanks for posting.

Looking back on your experiment, what would you change?

The dissolution medium commonly used for testing Rabeprazole enteric-coated tablets is acidic buffer solutions such as Simulated Gastric Fluid (SGF) with a pH of 1.2 for the initial stage and then transitioning to Simulated Intestinal Fluid (SIF) at pH 6.8 to simulate conditions in the stomach and intestines, respectively. These buffers help to mimic the pH conditions the tablet will encounter in the gastrointestinal tract and assess its release characteristics.

The candle flame has 4 zones from innermost to outermost:

1)Blue zone: It is near the base of the flame. Here the fresh air rapidly mixes with was vapour formed from the molten wax.A part of wax vapour completely burns and gives rise to blue flame.

2)Dark inner zone: This part consists of unburnt wax vapour given off by molten wax.It is the coldest part of the flame It is dark because of of decomposed carbon particles.

3) Luminous zone: In this zone partial combustion takes place with liberation of a lot of heat. This zone is hotter than the dark inner zone.

4) Non luminous zone:It is a zone were complete combustion takes placeIt is hottest part of the flame and is hardly visible.

For example stainless steel is practically insoluble in water.
