Compare and contrast two ways of forming fossils?
A fossil is not alive, but mold is.
Both either used to be, or are living.
Mold feeds on organic matter, while a fossil doesn't.
In general they're not very similar at all. Mold is something that decomposed organic matter, while a fossil is a preserved remain or trace of an animal, plant, or another organism.
What issues were important in 1984 election?
The 1984 election was dominated by issues such as the economy, national defense, and foreign policy. President Reagan's record on economic recovery and his strong stance against communism were key points of debate. The Democratic nominee, Walter Mondale, focused on social welfare programs and criticized Reagan's economic policies.
Ductility is the characteristic of a metal or another material that allows it to be drawn or rolled to be made longer without the material breaking. To get a little more technical, it is the ability of a material to undergo plastic deformation without failure. It is one of the physical properties of a material. Some nice, soft taffy can be pulled and will "string out" without breaking. But if that taffy is cold and not completely processed, pulling on it will result in a little stretching and a quick break. The metals copper, which is drawn into wire for use as an electrical conductor, and aluminium, which is rolled repeatedly until it is turned into foil which we use in the kitchen, are both metals with high ductility. Their ductility and some other physical characteristics make them ideal choices for the common applications mentioned. A link can be found below.
The ductility of steel for concrete reinforcement can be defined as an ability to achieve significant deformations without marked increase of stresses beyond the yield strength of steel. This term applies to the behavior of a construction in the conditions of nonlinear deformations, in which ductility plays an important role.
For many years there have been observed large differences between the actual durability of statically indeterminable elements of a construction and the values determined according to the principles of linear - elastic theory. The next phenomenon observed was the behavior of a construction at the load close to the destructive load, when there followed a considerable increase of deformations in the presence of a small increase of stresses. More recently, it has become more and more popular to apply the plasticity theory to the construction calculation. It is related to the developed knowledge in this area, the greater power of computer calculations as well as to the introduction of the simplified computational method, taking the plasticity condition under consideration, which relies on the assumption of redistribution of bending moments in a calculation carried out with the linear elastic method. The need for ductility Yield strength is a property of steel used for calculation of reinforced concrete constructions. Regarding the stretch of steel, the standards (e.g. PN-B-03264:2002) determine two parameters of reinforcing steel: the yield strength for a given grade of steel and the tensile strength.

The need for ductility in construction, which cannot be ensured by concrete, is met entirely by steel.

Which ingredient gives the shimmery effect in pearlised enamal?
The shimmer effect in pearlized enamel is typically achieved by adding mica or other similar reflective pigments to the enamel formulation. These pigments reflect light and create a shimmery or pearlescent appearance in the enamel when applied and dried.
How do you write Field of study?
"Field of study" can be written as a general reference to the area of academic specialization or interest that someone has chosen to focus on in their education or professional development. It typically refers to a specific discipline or subject area, such as biology, psychology, or engineering.
Technology can be both a friend and a foe. It has the potential to enhance communication, access to information, and productivity. However, technology can also lead to issues like privacy concerns, addiction, and job displacement. Ultimately, how we use and manage technology determines whether it is a friend or a foe.
What is the definition of experimental research?
Experimental Research:
Experimental research is guided by educated guesses that guess the result of the experiment. An experiment is conducted to give evidence to this experimental hypothesis. Experimental research, although very demanding of time and resources, often produces the soundest evidence concerning hypothesized cause-effect relationships.

AN INTRODUCTION TO GEMOLOGY...Gemology is the study of gemstones. Some dictionaries define it as the "scientific study of gemstones," but it is almost impossible to remove the scientific element. There may be investors whose only interest is in the value of the stones, but if they ever need to distinguish one gem from another, they are dealing with science. ... There are many categories of gemologists. For the jeweler it is a key element of their business. They need to be able to answer their customer's questions and identify the gems brought into them. ... The gold smith needs specific knowledge about the physical characteristics of gems. A setting that would be ideal for a diamond would be inappropriate for an opal and vice versa. The amount of pressure used to set the prongs on a garnet would break a tanzanite. ... Some gems will withstand the heat of repair work that involves high temperature soldering. Some can be left in the setting if steps are taken to moderate the amount of heat they receive. Still others are so heat sensitive they need to be removed. ... The lapidary also needs special knowledge. Cutting and polishing techniques vary from gem to gem. What would work well for one material would be a waste of time on another and disastrous on something else. ... When faceting thought needs to be given to color management. How the rough is oriented can make a lot of difference in the appearance of the finished gem. The style of cutting is also a part of color management. The choice of cut can lighten or darken a gem which will have considerable effect in both the appearance and the value of the stone. ... The choice of a cut, which includes the shape, number and location of facets, also influences the brilliance of the gem. The angles the facets are cut at have to be carefully chosen. Then these factors are balanced, or compromises made, so as to not sacrifice too much material in the pursuit of beauty. ... Another category of gemologist are the scientists. These are people with degrees in geology, chemistry and sometimes physics. While one of the smallest categories of gemologists, they are at the same time one of the most influential. ... At the heart of gemology is gem identification. Some rubies and garnets are impossible to tell apart from each other by observation, but their values are considerably different. A precise and accurate means to tell them apart is absolutely necessary. ... When dealing with whole crystals, the ruby and garnet are easy to distinguish. Garnets form in the cubic system. While they vary in shape, they tend to be roundish and the number of sides is always a multiple of four. Rubies on the other hand, form long thin crystals. They are in the hexagonal system and always have six sides. ... Most of the material that gets cut into gems isn't found in whole crystals, but in broken pieces. Using the techniques of mineralogy, they are easily distinguished from each other. Scratch tests, where the unknown is scratched by various substances, will determine its hardness. Other useful tests are the reaction to acids and the flame of a blow torch. These are categorized as destructive tests and are obviously inappropriate for cut gems. ... For centuries it was the lapidary who was in a position to most easily recognize the differences in like appearing gems. During the cutting process gems get viewed intently, a perspective that no other gemologist has. Identifying inclusions are given a lot of attention, then as many as possible removed. Differences in hardness are readily apparent when cutting and polishing, as are other characteristics. ... A method needed to be devised where cut gems could be identified without damage. To this end scientists began to first, identify the measurable physical and optical properties of our gems. Next they devised instruments to measure these properties. There was a long process of systematically measuring and recording these properties so they could be looked up. (Though well established, this is actually an ongoing process.) Eventually all this got put together into methods that could be used by people without extensive scientific backgrounds or large and expensive laboratory equipment. ... That is not to say that it doesn't require substantial education to identify gems. It is a large and complex subject that is continuing to increase in complexity as new gems are discovered and new ones are created in the laboratory. However, one doesn't need a degree in chemistry or physics to simply measure the properties of our gems. The most esoteric part was discovering those properties and creating the tools to measure them. ... If you are interested in learning about gems the first step would be to learn how they are categorized. Also important in the early stages is learning the terminology used to describe gems. Next you can learn what the physical and optical properties are. When you have this background, you can get into gem identification. ... Of course there are many side roads to travel. You may find a fascination with phenomenal gems or their inclusions. Many people find a desire to collect gems and this often leads to making jewelry or learning how to cut gems. ... Whether your interest is casual or professional, there is much to delight and amaze. It is something you can do from your desk, or something that allows you to get your hands dirty. Plus the subject of gemology is one of those where you will never run out of new elements to discover.
Can giving up smoking give you a bad taste in your mouth?
Yes, quitting smoking can initially lead to a bad taste in your mouth as your body adjusts to the absence of tobacco and clears out toxins from your system. This unpleasant taste is typically temporary and will improve as your body begins to heal from the effects of smoking. Drinking plenty of water and maintaining good oral hygiene can help reduce this side effect.
Compare solids liquids and gases in terms of their shapes and volumes?
Solids have a definite shape and volume. Liquids have a definite volume, but no definite shape - they take the shape of their container. Gases have no definite volume and no definite shape - they expand to fill their entire container.

[Middle English fresen, from Old English frosan; see preus- in Indo-European roots.]
freeza·ble adj.
Word History: Describing the landscape of Hell in Book II of Paradise Lost, Milton depicts "a frozen Continent . . . beat with perpetual storms . . . the parching Air Burns frore, and cold performs th' effect of Fire." It is evident from these lines that frore has some relationship to frozen, but what exactly is it? The Modern English paradigm for the verb freeze is freeze, froze, frozen, with a z throughout. However, in Old English, the principal parts were frosan, fras, froren. The r in the past participle froren is from a prehistoric s that became r by Verner's Law, a sound shift that changed s in certain positions into r. (The effects of Verner's Law can also be seen in such modern English pairs as was and were, and lose and (love-)lorn.) During the Middle English period, a new past participle frosen was created using the s from the first two principal parts; this survives as frozen nowadays. The older participle, spelled froren or frore in Middle English, lived on as a poetic word for "cold," but well before Milton's day it had become archaic in the standard language.

A book reflection is a personal response to a book that involves summarizing the main points or themes, analyzing the author's writing style or message, and discussing your thoughts and feelings about the book. It requires critical thinking and introspection to explore the impact the book had on you as a reader.
Is working together considered plagiarism?
If the assignment, as set, requires group work there is no problem. If you get others to help you with an assignment there may be problems, depending on the kind of help given. Practical, 'how-to' advice such as tips on which websites and books to use or how to put apparatus together in a laboratory should generally be all right, but getting someone else to do the work for you is cheating. It seems to me more a matter of academic honesty than plagiarism.
How was religion important to the development of the cultures of Asia?
Religion played a significant role in shaping the cultural beliefs, values, and practices of various Asian societies. It served as a unifying force, providing moral guidelines and a sense of community. Additionally, religious institutions often wielded political power and influenced the cultural and artistic expressions of these societies.
A place is considered historical for different reasons. Usually it is because something important happened there. For example, Hopewell Furnace National Historic Site in PA was where cannons for the Continantal Army were made during the Revolution. Fort Buford Historic Site in ND is where Sitting Bull, after the victory at Little Big Horn in 1876, returned to from taking refuge in Canada and surrendered in 1881. Nez Perce Chief Joseph was also imprisoned there. Some cities are historical because of important things that they are known for, such as Philadelphia both the Decaration of Independence and the Constitution were written there. It does not have to be someone or something related to politics, it can be someone that contributed to society. Alexander Graham Bell's and John Wayne's birthplaces are also historical sites. In the South some of the antebellum mansions are registered historical places because of the architecture and their age. Some places are historical because they were part of the founding of a city, such as first court house, bank or school.
Diffusions refer to the spread of a substance or concept from an area of high concentration to an area of low concentration. In the context of technology, diffusions can also refer to the adoption and implementation of new technologies or innovations within a population or group.
How do the densities of solid liquids and gases compare?
The density of solid substances is generally higher than that of liquids, which in turn are higher than gases. This is because the particles in a solid are tightly packed together, while in a liquid they are more spread out, and in a gas, they are far apart.
Clonogenic assay is based on the ability of a single cell to grow into a colony.This helps us to know that every cell in the population fo rits ability to undergo unlimited division. This is to determine the cell reproductive death after treatment with ionizing radiation ,can also used to study about the effectiveness of other cytotoxic agents.
