Information Science and Libraries

Variable means 'can change'. If a science experiment is to produce clear information, we should change only one thing at a time. The condition we change is called the independent variable. For instance we might decide to change the temperature of hot water and see how that affects how long potatoes take to cook in it. Temperature is the independent variable, and cooking time is the dependent variable. If we want to be sure that changing the temperature is the only thing affecting the results, we must ensure nothing else changes from run to run. We must keep the size of the potatoes, their variety, the amount of salt in the water and the cooking vessel the same. These are the controls, or control variables.The controls are the substance or material or measurement in the experiment that stays constant and doesn't change while the variable is the object compared to the control which varies in results and can change through out the course of the experiment.

Plant stems transport water and nutrients from the roots to the rest of the plant via xylem tissue, while distributing sugars and other organic compounds produced during photosynthesis throughout the plant via phloem tissue. This dual function allows plants to both absorb essential resources and distribute energy efficiently.

Yes, real diamonds do not melt ice. Diamonds have a very high melting point of about 4,027 degrees Celsius (7,280 degrees Fahrenheit), much higher than the temperature required to melt ice.

A type of mudflow associated with violent eruptions is called a lahar. Lahars are fast-moving mixtures of water, volcanic debris, and mud that can travel down the slopes of a volcano at high speeds, posing a significant hazard to anyone in their path. These mudflows are often triggered by the rapid melting of snow and ice during an eruption or heavy rainfall.

Three sequential mRNA nucleotides are called a codon, which codes for one amino acid.

mRNA or messenger RNA has to carry the protein code from the nucleus to the cytoplasm for protein synthesis. It is like a VERY long sentence (or word) in a book. Proteins, being complex need a lot of letters so they are strung out. The other types of RNA, tRNA (transfer RNA) and rRNA (ribosomal RNA) have different functions and do not have to be so long. tRNA only has to carry a single amino acid (protein building block) and rRNA is used to attach this to the end of a protein.

it is a type of RNA molecule that is made up of about 75 nucleotides. there are at least 20 different types of RNA for each amino acid. the rna is folded to for a t shaped structure like a clover leaf.

it has the following arms:

1) anticodon arm-contains 5 bp stem and an anticodon loop and a Y strand for modifies purine nucleotides.

2) T arm- has a 5 bp stem and T pseudouridine C sequence.

3) a D arm- has a 4 bp stem and a loop containing dihydrouridine.

4) an accepter stem-made up of 5' terminal phosphate group and 3'OH terminal nucleotide that has a CCA base that attaches the amino acids and recognisestRNA enzyme. it has 7bp stem.

5) variable stem.

It is really hard to make insulating materials charged.

There is very large gap between conducting band and a valence band.

It would require a lot of energy to make electrons jump from the valence band and go into conducting band.

Work is force times distance.

A Force divided by Distance: looking at the units,

Force = newtons = kg m / s^2 = mass x length / time^2 so ML/T^2

Distance = m = length so L

Force/Distance = (ML/T^2)/L = ML/LT^2 = M/T^2

So the units of a force divided by distance are mass/ time^2

This would be the rate of change of mass change with respect to time.

The start codon on an mRNA is always AUG. It codes for the amino acid methionine and signals the start of translation.

I want to knkow which type of rice is used for making Puffed Rice...There is a Different type of rice available in the market so i want to about the type & any one know how to make Puffed Rice plz Guide also.

Phylum (Chordata), as class is located at a lower taxonomic level than phylum for classification of organisms.

Freshly squeezed orange juice is a heterogeneous mixture, specifically a suspension. This is because the pulp and other insoluble particles from the orange are suspended in the liquid portion of the juice.

Ingesting rust itself would not typically result in death. However, if someone consumes a significant amount of rust that contains toxic substances or contaminants, there is a risk of poisoning which could potentially lead to death. It is important to seek medical attention if someone has ingested something potentially harmful.

the reason is that certain gases, dubbed greenhouse gases by us scientists have the ability to trap heat radiation from the suns rays in our atmosphere, heat that would normally dissipate into the vacuum of space. those gases include methane and carbon dioxide. when in suitable amounts those gases are actually beneficial to life on earth as without them the earth would be far too cold to support any interesting life. unfortunately human activities are releasing huge amounts of said greenhouse gases into the air, meaning that more heat rays are trapped and hey presto, the world heats up

It takes the moon approximately 27.3 days to complete one orbit around the ecliptic, which is the apparent path of the sun in the sky as seen from Earth. This period is known as the sidereal month.

Yes, if a mixture scatters light and does not settle upon standing, it is likely a suspension. Suspensions consist of larger particles that are not soluble in the solvent and remain suspended due to their size and density.

Heat energy helps us in many ways, such as keeping our homes warm, cooking food, and generating electricity. It also plays a crucial role in various industrial processes, like manufacturing and transportation. Additionally, heat energy is essential for our bodies to function properly and maintain the required temperature.

Water will release the greatest amount of heat when 1.00 mol is frozen because it has a high heat of fusion compared to other substances. The heat of fusion of water is 6.01 kJ/mol, which is higher than most other common substances.

Materials like glass, water, and air are known for transmitting light because they allow light to pass through them with minimal absorption. Scattering of light occurs when it interacts with rough surfaces, particles, or molecules in the medium, leading to its redirection in different directions. Examples of materials that scatter light include fog, frosted glass, and certain plastics.

Vision is not needed for taste, although the presentation of a plate can increase the appreciation of a meal.

The sense needed for taste is smell. A large part of taste is sensing the volatile compounds released as you chew. The tongue can only sense sweet, salt, sour and bitter. There is a classic experiment, usually performed in High School Biology classes: the subject is blindfolded so they can't see what is being offered, and the nose is plugged so the sense of smell is removed. The experimenter offers some chopped raw potato to be chewed and swallowed. He then offers chopped raw onion to be chewed and swallowed. The subject cannot tell the difference between the two foods until the nose is unplugged, at which point there is a violent reaction when the volatile oils in the onion hit the sensors in the inner parts of the nose and sinuses,

There have been studies done with elderly people complaining that food has no taste anymore, and it's been found that the problem is not reduced sensitivity in the tongue and mouth, but a reduction in the sense of smell.

Yes, the Moon does alter in size to an Earth based observer. This is a real effect caused by the fact that the Moon's orbit round the Earth is not a perfect circle but rather it is an ellipse. The elliptical orbit brings the Moon nearer to the Earth at Perihelion and takes it further away at Aphelion thus at Aphelion it is smaller to the eye than at Perihelion. The Moon also APPEARS to be bigger to the eye when it is close to the horizon this is called the Moon illusion. The link I will place below explains this.
