Please answer this: Given the background: Matter, dark matter, and dark energy are distributed homogeneously throughout the Universe over length scales longer than 300 million light-years or so. However, over shorter length-scales, matter tends to clump hierarchically; many atoms are condensed into stars, most stars into galaxies, most galaxies into clusters, superclusters and, finally, large-scale galactic filaments. The observable Universe contains approximately 300 sextillion (31023) stars and more than 100 billion (1011) galaxies. Typical galaxies range from dwarfs with as few as ten million (107) stars up to giants with one trillion (1012) stars. Between the larger structures are voids, which are typically 10150 Mpc (33 million490 million ly) in diameter. The Milky Way is in the Local Group of galaxies, which in turn is in the Laniakea Supercluster. This supercluster spans over 500 million light-years, while the Local Group spans over 10 million light-years. The Universe also has vast regions of relative emptiness; the largest known void measures 1.8 billion ly (550 Mpc) across. and the situation: Rob is an amateur astronomer. He was looking at the sky with his telescope. First he took a longer length observation. He noted his observation as case A. Then he took a shorter length observation. He noted that observation as case B. He found that it's beneficial to take both observations to get a fuller view of the observable universe. Answer the following question: In case B would matter be distributed less or more homogeneously than in case A?

Answer: less

Problem: Given the background: When the temperature of reactants is higher, the rate of the reaction is faster. At higher temperatures, particles of reactants have more energy, so they move faster. As a result, they are more likely to bump into one another and to collide with greater force. For example, food spoils because of chemical reactions, and these reactions occur faster at higher temperatures (see the bread on the left in the Figure below ). This is why we store foods in the refrigerator or freezer (like the bread on the right in the Figure below ). The lower temperature slows the rate of spoilage. and the situation: Rob is a chemist with a pharmaceutical company. He is trying to devise a technique that would be able to control chemical reactions. For that, he conducted two tests. In the first test, he used warmer reactants. He called it reactant A. In the second test, he used cooler reactants. He called it reactant B. Answer the following question: Would particles would collide with smaller or greater force in reactant A than in reactant B?

A: greater

Problem: Given the question: Given the background: Sugaring is a food preservation method similar to pickling. Sugaring is the process of desiccating a food by first dehydrating it, then packing it with pure sugar. This sugar can be crystalline in the form of table or raw sugar, or it can be a high sugar density liquid such as honey, syrup or molasses. The purpose of sugaring is to create an environment hostile to microbial life and prevent food spoilage. Sugaring is commonly used to preserve fruits as well as vegetables such as ginger. From time to time sugaring has also been used for non-food preservations. For example, honey was used as part of the mummification process in some ancient Egyptian rites. A risk in sugaring is that sugar itself attracts moisture. Once a sufficient moisture level is reached, native yeast in the environment will come out of dormancy and begin to ferment the sugars into alcohol and carbon dioxide. This leads to the process of fermentation. Although fermentation can be used as a food preservation method, it must be intentionally controlled, or the results will tend to be unpleasant. and the situation: John has to live in the tundra for six months. He is preparing for the harsh arctic winter. He bought three bags of foods, bag A, bag B, and bag C. He kept bag A on his table top. Just out of curiosity, he applied the sugaring method he learned from the internet on bag B and bag C foods. Afterwards, he kept the bag B foods in a place with no moisture, and the bag C foods in a place with high moisture. Answer the following question: Which foods would be more susceptible to spoilage, bag A or bag B?
++++++++++++++++++++++++++++++++
The answer is:
bag A

Q: Given the background: Declines in population size can result in a loss of genetic diversity, and owing to genetic variation's role in the evolutionary potential of a species, this could in turn result in an observable Allee effect. As a species' population becomes smaller, its gene pool will be reduced in size as well. One possible outcome from this genetic bottleneck is a reduction in fitness of the species through the process of genetic drift, as well as inbreeding depression. This overall fitness decrease of a species is caused by an accumulation of deleterious mutations throughout the population. Genetic variation within a species could range from beneficial to detrimental. Nevertheless, in a smaller sized gene pool, there is a higher chance of a stochastic event in which deleterious alleles become fixed (genetic drift). While evolutionary theory states that expressed deleterious alleles should be purged through natural selection, purging would be most efficient only at eliminating alleles that are highly detrimental or harmful. Mildly deleterious alleles such as those that act later in life would be less likely to be removed by natural selection, and conversely, newly acquired beneficial mutations are more likely to be lost by random chance in smaller genetic pools than larger ones.Although the long-term population persistence of several species with low genetic variation has recently prompted debate on the generality of inbreeding depression, there are various empirical evidences for genetic Allee effects. One such case was observed in the endangered Florida panther (Puma concolor coryi). The Florida panther experienced a genetic bottleneck in the early 1990s where the population was reduced to 25 adult individuals. This reduction in genetic diversity was correlated with defects that include lower sperm quality, abnormal testosterone levels, cowlicks, and kinked tails. In response, a genetic rescue plan was put in motion and several female pumas from Texas were introduced into the Florida population. This action quickly led... and the situation: Molly and Brian are two friends who moved away from one another after becoming close in college. They still talk on the phone regularly and see each other a couple times a year. During a recent conversation, the subject of population comes up. Molly's town is currently increasing a steady decrease in population, and Brian's town has been seeing an increase in population. Answer the following question: An Allee effect is not currently happening in which town?
A:
Brian's town
