Comparisons

People often examine things and objects by comparing their similarities or differences in order to judge the specific characteristics, qualities and the degree of their merit. This category includes all the questions and answers to relate things with their similarities and to distinguish with their differences that decide their specific nature in contrast to their counterparts being compared.

What is the relationship between transistor densities and the improvement in computer speed and miniaturization?

Of course a less dense transistor would be smaller enabling you to fit more of them in a confined space. Then you have the challenge of making a less dense transitor work as fast for it is less conductive. This is silcon technology.

What are the three types of chemical bonds?

Covalent- Strongest (Split up into polar and nonpolar)

Ionic

Hydrogen- Weakest
Three types of chemical bonds include the ionic bond, the covalent bond, and metallic bond. Ionic occur between oppositely charged ions, covalent bonds occure when atoms share electrons. Metallic bonds form in metals. Basicaly, in metals, the atoms of each metal share their electrons in a "sea of electrons."

Which one of the five makes the best comparison fwawwfa is to 9323392 as affwwaf is to?

This comparison is based on the reverse order of the letters in the words. Therefore, applying the same pattern, the answer would be 2939239.

In a concentrated solution there is?

a high amount of solute relative to the amount of solvent. This results in a high concentration of solute particles in the solution, making it more potent or intense compared to a diluted solution.

What is the definition of outwash?

Outwash is a glacial deposit formed by the melting and retreat of a glacier, resulting in the sediment being washed away by meltwater and deposited in front of, beside, or beyond the glacier. It typically consists of sands and gravels that were transported and sorted by the flowing water.

What is the definition of pestle?

A pestle is a tool used for grinding. It is usually paired with a mortar, which is a solid robust bowl. The pestle is a heavy rod with a rounded end that is used to grind items within the mortar.

PESTLE stands for - Political , economical , social, technological, legal and environmental.

Where can one find an extractor for a Marlin 50E also known as a Ranger 34A?

The marlin model 50 and model 50e do not use an extractor. There is only an extractor pin/post.

Try these sources:

Numrich gunpartscorp.com

Jack First jackfirstgun.com

Bob's Gun Shop gun-parts.com

Some versions of the model 50 do indeed have a manual extractor. It sets in a slot in the side of the rifle, just ahead of the bolt handle slot. I suppose it's main use is to extract an unfired round. Many are lost and never replaced. I'd sure like to find one

What is the epicenter of an earthquake?

The epicentre of an earthquake is the point on the Earth's surface directly above the point within the Earth where the earthquake actually occurred (known as the focus or hypocentre).

From this point on the surface the waves of the earthquake radiate outward like the ripples in a pond when a stone is thrown in.

How are artificial sweeteners compared with natural sweeteners?

The calorie-free sweeteners permitted now in Britain

Saccharin

Discovered in 1879, this molecule (formula C7H5NO3S) is about 300 times as sweet as sucrose. It has a bitter aftertaste.

Aspartame

The molecule is two amino acids, aspartic acid and phenylalanine, linked by a methyl group. It is about 200 times as sweet as sugar and has no aftertaste. It breaks down slowly at room temperature, and rapidly at higher temperatures, making it unsuitable for baked foods. People with the inherited disease phenylketonuria cannot tolerate phenylalanine

Acesulfame-K

The molecule contains sulphur and nitrogen, is up to 300 times as sweet as sugar and is rapidly gaining a foothold on the market in soft drinks, desserts and puddings.

Thaumatin

Derived from the plant Thaumatococcus daniellii, this is a large peptide polymer whose taste builds up slowly. Less than 1 per cent of the British population currently consumes it. It can be used to sweeten a variety of products, such as chewing gum, jam and soya sauces.

Sweeteners that will probably be permitted in 1992:

Cyclamates

These are the calcium and sodium salts of cyclamic acid. They are only 30 times as sweet as sugar, but are widely used in foods, drinks and pharmaceuticals. Britain banned them in 1969.

Neohesperidine DC

A substance derived from oranges, now used for speciality beers in Belgium. No other country currently permits it to be used as an additive.

*Intakes of Intense and Bulk Sweeteners in the UK, 1987-1988, HMSO, 1990

From issue 1735 of New Scientist magazine, 22 September 1990, page

  • Sucralose is found as Splenda. You can use it in hot and cold foods, including in baking and cooking. Processed foods often contain it.

What is the cost comparison for crushed concrete vs lime rock?

This pricing will be extremely regional and based on available supplies. That said, in central Florida I'm currently looking at $26/cy for limestone (57's) and approx $19-20/cy for crushed concrete that is DOT approved.

Hope this helps.

On April 5th 2010 I got an estimate for $45.00/cubic yard for limerock - Rex D.

What is a polygene?

A polygene is a group of multiple genes that work together to influence a particular trait or characteristic in an organism. These genes may have additive effects, meaning the more present, the stronger the trait. Polygenes are often involved in complex traits like height or skin color.

What do you call a phobia of elbows or joints especially double jointedness?

There is no specific term for a phobia related to elbows or joints, including double jointedness. Phobias related to specific body parts are uncommon, and if someone has an intense fear of elbows or joints, it may fall under a broader category of specific phobias or somatic symptom disorders. It is important to consult a mental health professional for a proper diagnosis and treatment.

How light travels?

Simply put, light travels in straight lines. If you want to prove this, look at a beam of light coming from a small torch, or find a tube or hose. You can see through the tube when it's straight, but if it's bent, you can't see anything.

How do you build an elbow joint?

An elbow joint is a complex structure of bones, ligaments, and tendons. To build a model or understand its construction, you would need to study the anatomy of the humerus, radius, and ulna bones, as well as the ligaments and tendons that connect them. This information can be found in anatomy textbooks or online resources.

What is the definition of genomic footprinting?

Same as genetic footprinting, only at a high throughput, systems level way. Typically you use a transposon library to insert mutations to cells that inactivate genes (you assume one transposon/inactivation per cell). Then you trascription profile (dna microarray, rna-seq) after selection (whatever you want to select for, growth, resistance etc) and try to map the mutations/genes inactivations to the fitness changes in the cells.

For example if you select for growth in a particular environment and the deletion of a gene confers this, then during selection that mutant will be over-represented, so when you run a microarray, you will see no expression of the deleted gene in reference with the wild type strain.

How deep can light travel in ocean?

In the first 3 ft., more than half of the light that penetrated the surfaces is absorbed by the water. Red is the first to be completely absorbed.

By 30 ft., only 20% of the original amount of the surface light is still visible.

Blue light is the last to go. At around 100 meters or 330 ft, only .5% of light is visible.

Red: 1 m/ 3.3 ft

Yellow: 10 m/ 33 ft

Green: 50 m/ 165 ft

Blue: 100 m/ 330 ft

What activities make plant and animal cells different in how they obtain energy?

One of the ways that plant and animal cells differ in how they obtain energy is the chloroplasts in plants. Plants take visible light, mostly red and blue, however they do take some green light waves, in through their chloroplasts, and do photosynthesis with the energy that they have attained from the sunlight. Plants are autotrophes; meaning they obtain their energy from abiotic sources, such as sunlight or inorganic chemicals. Animals are heterotrophs; meaning they obtain their energy and nutrients by consuming other organisms. I hope that helps!

What is the relationship between genectics and hereditary material?

Genetics is the study of how traits are passed from parents to offspring through hereditary material. Hereditary material, such as DNA, carries genetic information that determines an individual's traits and characteristics. Genetics explores how this information is inherited, expressed, and passed on to future generations.

What is the act of making land suitable for human use?

The act of making land suitable for human use is known as land development. This involves altering the land to prepare it for construction or other human activities, such as grading, paving, and installing utilities. Land development can range from residential subdivisions to commercial developments.

What is the difference between a mixed culture and a contaminated culture?

A mixed culture is a container that holds two or more identified and easily differentiated species of microorganisms. A contaminated culture was once pure or mixed (and thus a known entity) but since had contaminants (unwanted microbes of uncertain identity) introduced into it.

What is a mechanical mixture?

A mechanical mixture or heterogeneous mixture is a mixture with different parts that you can see. For example an omelette is a mechanical mixture because you can see the different parts that make up the omelette.

What is the definition of microflora?

The bacterial colonies found in the large intestine. These bacteria are important for proper digestion and fecal excretion of waste products.

I think micro means small or microscopic, and flora is from botany, meaning plants. So, I think this meant the microscopicplants of either land or water, because plants live in both soil and water. I don't know about the bacteria found in the intestines, I think that would be microbiological, or microorganism, don't place any huge bets on that, but I think that might be right.

In microbiology, flora (plural: floras or floræ) refers to the collective bacteria and other microorganisms in an ecosystem (usually in human and animal hosts or in a single part of itsbody)

Why is alcohol used in thermometers?

AnswerAlcohol can be used in some thermometers due the fact of its very low freezing point. It may be used in cold atmospheres such as freezers. It however would not be suitable in vey hot atmostpheres due to the boiling point.

because of it's very low freezing point
