what is the transport process for a methane gas leak? Solution Scientists have developed a material made out of a mixture of silica and water which can soak up large quantities of methane molecules. The material looks and acts like a fine white powder which, if developed for industrial use, might be easily transported or used as a vehicle fuel. Methane is the principal component of natural gas and can be burnt in oxygen to produce carbon dioxide and water. The abundance of the gas and its relatively clean burning process makes it a good source of fuel, but due to its gaseous state at room temperature, methane is difficult to transport from its source. Many natural gas reserves are geographically remote and can only be extracted via pipelines, so there is a need to look for other ways to transport the gas. It has been suggested that methane gas hydrate could be used as a way of containing methane gas for transportation. The disadvantage of methane gas hydrate for industry use is that it is formed at a very slow rate when methane reacts with water under pressure. To counteract these difficulties, a method to break water up into tiny droplets to increase the surface area in contact with the gas can be used. Mixing water with a special form of silica – a similar material to sand – which stops the water droplets from coalescing. This ‘dry water’ powder soaks up large quantities of methane quite rapidly at around water’s normal freezing point. ‘Dry water’ could be more economical than other potential products because it is made from cheap raw materials. The material may also have industrial applications if methane could be stored more conveniently and used to power clean vehicles..

Compare and contrast protein import into the ER and into the nucleus. List at least two major differences in the mechanisms and speculate on why the nuclear mechanism might not work for ER import. Solution The Proteins are imported into the nucleus from the cytoplasm only after thay have been synthesized,folded and properly assembled into complexes. They carry a sequence of amino acids that acts as a tag called as Nuclear localization signals (NLS) ,bound by importins. In contrast, all the unfolded polypeptide chains will be imported or translocated into ER as they are been made by the ribosomes. Though ribosomes function in the cytosol they are assembled in the nucleus where as the enzyme complexes function in the nucleus and assembles in the cytosol. But, both these ribosomes and enzyme complexes are transported through a nuclear pore intact. These Nuclear pores are gates, always opened for small molecules; in contrast, translocation channels in the ER membrane will be normally closed and open only after the ribosome has attached to the membrane. The ER membrane remains impermeable to small molecules during the translocation process, as the ER is a major store for Ca2+ ions in the cell, and Ca2+ ions released into the cytosol must be tightly controlled. Nuclear localization signals (NLS) are not cleaved off after the protein is imported into the nucleus; in contrast, ER signal peptides are usually cleaved off. Nuclear localization signals (NLS) are needed inorder to reimport nuclear proteins repeatedly after they have been released into the cytosol i.e during mitosis, when the nuclear envelop breaks down..

Dimitri and Rita eat some donuts for breakfast and then spend the morning at an amusement park. After a few hours of riding the Super Looper Double Twist Dimitri feels nauseous and regurgitates the donuts. Rita is fine, but Dimitri has developed a ________, and the next time they stop for donuts, Dimitri immediately feels ill. a. taste aversion b. taste response c. unconditioned aversion d. unconditioned response Solution Taste aversion is a condition which is generally developed after ingestion of food that causes nausea, vomiting, and sickness. This condition serves as a mechanism to avoid poisonous substances before they can cause harm to our body. This condition is most commonly seen in human beings. When a person eats bad food, he develops nausea and becomes aversive to that food. The same thing happened in the above case. Dimitri has developed a food aversion for donuts. The next time they stop for donuts, Dimitri immediately feels ill. Therefore, option A is correct..

\"Ageism disproportionately affects women since they outlive me.\" This could be understood as a form of intersectionality. FIRST explain the concept of intersectionality. THEN, identify and explain two other ways (i.e. not pertaining to the intersection of advanced age and gender) in which intersectionality might negatively affect medical treatment and/or outcomes. FINALLY, identify and explain one way in which each of those negative effects could be migrated or counteracted. Suggested term(s): intersectionality, intersectionality and health disparities. Solution Intersectionality is the study of the overlapping (intersecting) social identities of oppression, domination or discrimination. identities which intersect include gender, race, social class, ethnicity, nationality, sexual orientation, religion, age, mental disability, physical disability, mental illness, and physical illness etc.,. Incase of intersectionality of mothers with HIV the mothers does not reveal that they have HIV due to their cultural problems and does not take treatment for their disease. They have additional responsibility of taking care of their children and other house hold activities. The negative effects could be migrated or counteracted by utilization of intersectionality to aid nurse scientists in knowledge development and inform nursing practice regarding issues of social injustice and health inequities there by the people under the need have awareness about the treatment and the need for it..

2. The Lorenz curve measures inequality in person income distribution. What is the difference between personal income distribution and functional income distribution? Solution Personal income distribution shows differences in income of citizens among a nation. On the otherhand, functional income distribution may occur due to difference in factor rewards to production, viz. wages, rent, interest and profits. The former one belongs to the discussion of labour market and the later one is determined in input/factor market that ultimately show factor rewards..

1.) In some forms of epigenetic modification, when a gene is “marked”, a.) its expression is semi-permanently altered. b.) it is tagged for deletion. c.) its genetic code is temporarily modified. d.) all of the above 2.)A case in which Littorina snails upregulate shell deposition and develop a thicker shell when crabs are present is an example of: a.) seasonal polyphenism b.) phenotypic plasticity c.) genomic imprinting d.) amplification Solution 1. (a) its expression is semi-permanently altered. 2. (b) Phenotypic plasticity Phenotypic plasticity refers to the ability of a genotype to exhibit alternative morphological, behavioral and physiological characteristics in response to environmental condition. Inducible defenses are a ubiquitous form of plasticity that involve the production of chemicals, morphologies, or behaviors by prey species in response to predator cues. These changes reduce prey vulnerability to inducing predators or herbivores..

Will th ebelow code work andif not please help me fix it. Basically I am taking in a line of code and we are supposed to use fail state to figure out which kind of format the line will follow. It will either follow one of two formats. So I am trying to say if while reading in it hits something that doesn\'t work it must be the OTHER kind of line. Am I using clear and fail functions correctly? It is important that when it fails the next value being read in goes into the place where it failed reading in. So if it tries to read something in and it fails the next value read in should go into THAT value and not the next one. Solution Reasons: i) You cannot start read vertexOne or vertexTwo, before you open the stream ii) Set up your file reading in streams based on the layout of your files, so what you can do is to have if-else statements that select the right stream setup bases on the filname. Program: #include \"Triangle.h\" #include \"Graphics.h\" #include \"Shape.h\" #include using namespace std; Triangle::Triangle() { } Triangle::Triangle(Point pt1, Point pt2, Point pt3, Color color) { vertexOne = pt1; vertexTwo = pt2; vertexThree = pt3; vertexOneColor = color; vertexTwoColor = color; vertexThreeColor = color; } Triangle::Triangle(Point pt1, Color col1, Point pt2, Color col2, Point pt3, Color col3) { vertexOne = pt1; vertexOneColor = col1; vertexTwo = pt2; vertexTwoColor = col2; vertexThree = pt3; vertexThreeColor = col3; } void Triangle::setColor(Color col) { vertexOneColor = col; vertexTwoColor = col; vertexThreeColor = col; } void Triangle::setVertexOne(Point pt) { vertexOne = pt; } void Triangle::setVertexTwo(Point pt) { vertexTwo = pt; } void Triangle::setVertexThree(Point pt) { vertexThree = pt; } Point Triangle::getVertexOne() { return vertexOne; } Point Triangle::getVertexTwo() { return vertexTwo; } Point Triangle::getVertexThree() { return vertexThree; } void Triangle::setVertexOneColor(Color col) { vertexOneColor = col; } void Triangle::setVertexTwoColor(Color col) { vertexTwoColor = col; } void Triangle::setVertexThreeColor(Color col) { vertexThreeColor = col; } Color Triangle::getVertexOneColor() { return vertexOneColor; } Color Triangle::getVertexTwoColor() { return vertexTwoColor; } Color Triangle::getVertexThreeColor() { return vertexThreeColor; } void Triangle::read(istream& ins) { // These are values of the each vertex and color Point vertex1; Point vertex2; Point vertex3; Color col; Color vertex1Color; Color vertex2Color; Color vertex3Color; ins >> vertex1 >> vertex1Color >> vertex2 >> vertex2Color >> vertex3; // Checks whether ins has entered a fail state of not if (ins.fail()) { ins.clear(); Triangle(vertex1, vertex2, vertex3, vertex1Color); } else { ins >> vertex3Color; Triangle(vertex1, vertex1Color, vertex2, vertex2Color,vertex3, vertex3Color); } } void Triangle::write(ostream& outs) { Point out_vertex1 = getVertexOne(); Point out_vertex2 = getVertexTwo(); Point out_vertex3 = getVertexThree(); Color out_vertex1Color = g.

Summarize the article \"Trading liberty for illusions\" by Wendy Kaminer in 300 words by following these steps: - the central idea of the passage - what, who, why, where, when and how - the author\'s conclusion - the subject of the description and it\'s key feature(s) Solution The central idea of the article is about how the September 11 attacks have affected the civilian population. In such circumstances, people are really scary and it is the responsibility of the government to take all necessary precautions to secure its citizens. But the actions adhered to go beyond the logical approach to safety by using several surveillance devices to track criminals or abnormal behavior. Kaminer accuses government of ignoring the civil liberties and the processes followed were pointless and demonstrated its failures. She further adds that Americans have had to trade their privacy with security, which means there is no privacy. The ways facial recognition was used and abused, she says it constitutes a threat to security and liberty, not a promise of security. The hard-core trained criminals fooled the intelligence surveillance system by suppressing their emotions, behaviors, and facial expressions which proved the systems to be highly inefficient. This leaves technology surveillance system a very controversial topic in the United States. She goes on to say that the government is divided between using law as it was intended or breaking law to meet special interest breaching security of the people it is supposed to protect. The government should not exploit the gullibility of the citizens, for dissenters will start questioning the credibility of the American philosophy. What she concludes is that though technological advancement is geared up at improving security, it should be relied upon as the most accurate measure against threat. The government need a sober approach to security and privacy and should not rely upon the existing systems, laws, and technology. *****.

what is a shared derived charterer and how is it useful for constructing a phylogeny ? Solution Phylogeny can be understood as the science of developmental history of an organism with respect to other organisms. Since the origin of an individual remains unknwon and developmental characters can be measures only relative to other known organisms, the science of phylogeny is based upon relavance of the features of a developing organism with respect to other organisms whose features have been already well studied. For this purpose, the extent of relatedness and differences between two or more organisms are generally studied. There are some features which remain exclusive for a species whereas some features are common in different species. These common features are termed as \'shared derived characters\' because it is supposed that owing to their presence, anatomical relavance and similarities in physiological function in different species, these features must have been orginated from a common ancestor and gradually shared by different species for development. Thus, the more is the number of shared derived characters between two or more species, the more likely is their evolutionary relatedness. For example, while constructing a phylogeny tree, the index of these shared derived characters remains highly useful. It helps in grouping and clssifying organisms based upon their evolutionary history and evident relatedness based upon number of shared characters. For example, all organisms with jointed feet are placed under phylum arthropoda. After that, organisms with paired feet and un-paired feet are differentiated either as millipeds or centipeds. After that, organisms are differentiated based upon their mouth structures and so on. Thus, the occurence of jointed feet, nature of feet and distribution of body plates on mouth cavity represent shared derived characters. These characters can be further elaborated at anatomical and molecular levels. Thus, this clearly explains the role of shared derived charterer and its usefullness for constructing a phylogeny tree..
