If a protein is destined to be a part of the cell membrane or to leave a cell, describe how the protein is processed and transported to the cell membrane. Solution The cellmembrane is chemically made of phospholipoprotein that is combination of phospholipid and protein. Though protein is an integral part of plasma membrane, it allows certain protein to enter into the cell through p.m.. The protein is known as membrane transport protein..which is of two types that\'s carrier protein and channel protein. Carrier protein may be open or closed to both external environment or extracellular fluid and internal environment or intra cellular fluid but channel protein is always open to both the environment allowing entery of ions, molecules and solutes and solvent. Due to this reason p.m. is selectively permeable allowing some proteins in to the cell and restricting others. The carrier protein is either open or closed to both external environment and internal environment. Active transport is done by sodium potassium transport mechanism. ATP (adenosine tri phosphate) is needed for active transport. Active transport occurs against the concentration gradient. Lipid bilayer is generally not permeable. So active transport occurs with utilisation of ATP against concentration gradient. Another type of transportation is facilitated diffusion. It doesn\'t require any energy. Generally the polar bodies, the charged bodies and dissolve molecules pass through the membrane by this mechanism. The hydrophobic tail of lipid molecules opposes the movement of soluble molecules..

How do angiosperms increase the likelihood that their embryos arc moved away from the parent plant? Why does moving the embryos away from the parent plant increase the success of the embryo? Solution Ans: Angiosperms are the flowering plants and most are terrestrial and all lack locomotion. Gametes are delicate single cells. For two plants to cross fertilize, there must be a mechanism for the two gametes to reach each other safely. There must also be a mechanism to disperse their offspring far enough away from the parent so that they do not have to compete with the parent for light, water, and soil minerals. Seeds from the parent plant need to be dispersed away from the plant to allow the seedlings a chance at survival without having to compete with the parent plant for space, nutrients and sunlight. Dispersion also allows the species to spread its population across a wider territory to ensure its continued survival. Explanation: When too many seeds are planted in the same pot or area, the seedlings tend to be weaker and more fragile because they have to compete with the other seedlings for resources. There are several ways in which seeds are dispersed naturally in plants. Gravity is sometimes sufficient to pull down heavy seeds from tall plants. The seeds then roll away from the parent plant and begin to grow. Animals also help with seed dispersion. The seeds can have surfaces that facilitate their sticking to the fur or skin of the animals so they can be transported as the animal moves around. When animals eat fruit containing seeds, the seeds pass through the animals\' gastrointestinal tracts unaffected and are excreted at different locations along with some fertilizer nutrients to help them grow. Some seeds are light enough or have special wing- like adaptations to allow for dispersal by wind. Other seeds can float in water and move along with streams to a new location where there are sufficient nutrients and no plants to compete with for water and sun. Sometimes, seed pods burst with enough force that the seeds get thrown over a distance to allow the seedlings to grow away from the parent plants. The numerous different ways in which plants have evolved to perfect their technique of seed dispersion is a telltale sign of how important it is for seedlings to grow away from the parent plants..

How did social revolution relate to warfare development? Solution Warfare has built up and devastated nations, it has molded and destroyed cultures, since the beginning of civilization, warfare has left its impact on humanity, and it affects every aspect of human culture and life. Some historians and psychologists argue that humans naturally engage in warfare. Therefore, as long as the human race continues to exist, so will the art of warfare. Others have different views, claiming that warfare arose as human civilizations developed, the politics involved between towns, states, and countries created the conflicts that raged into war. Although the origin and future of warfare remains uncertain, history shows that many changes took place throughout the existence of war. From the small tribal conflicts of primitive man to the global threat of nuclear warfare, warfare has drastically changed. This paper will discuss the evolution of warfare, as well as the impact that technology has on it. Defining warfare is a very difficult task. A simple definition is the use of physical force to settle disputes between organized groups. On the other hand, a more complex idea states that war is an organized struggle between groups in which each side seeks to displace or dispel, to dominate or to punish, or simply to be rid of the other, by inflicting what we call defeat. Gallie defines two eras of warfare: the classic and problematic stages. The classic phase of warfare lasted from the establishment of war until about two hundred years ago. During this period, war affected every day life. Many years were spent fighting wars. Even in times of peace, war was still anticipated, and thus kept everyone prepared for war. The opposing sides gathered to fight and display their army skills, resources, and bravery in order to overcome the enemy. The classic wars ended with the collapse of the Napoleonic Age. a social revolution is a bottom-up, as opposed to a vanguard party–led or purely political, revolution aiming to reorganize all of society. In the words of Alexander Berkman, social revolution means the reorganization of the industrial, economic life of the country and consequently also of the entire structure of society. More generally, the term \"social revolution\" may be used to refer to a massive change in society, for instance the French Revolution, the American Civil Rights Movement and the 1960 hippie or counterculture reformation on religious belief, personal identity, freedom of speech, music and the arts, fashion, alternative technology or environmentalism and decentralised media. Social revolution is contrasted with purely a political revolution in which the government is replaced, or the form of government altered, but in which property relations are predominantly left intact. Social revolutions do not imply necessarily that the working class as a whole has control over the production and distribution of capital and goods - in many countries this control.

Explain the benefit of designing a foundation with LRFD as opposed to ASD Solution The LRFD is certainly an improvement over the ASD. It takes better account of variability in both loading and resistance. LRFD is a reliability based design. Even before taking my reliability based design class, I always had my doubt in applying a single factor of safety for an output derived from inputs of varying reliability. The one disadvantage of LRFD is the lack of sufficient statistical data to select appropriate factors in certain specific cases, but still better than ASD..

describe the three major categorical theories of language development,as listed below .consider the emphasis each places on innate abilities versus environment influences.also attribute key terms and theorist with one if the following categories. write a one page report on a language theorist or researcher who asserts a position that is different from your own preferred notion. .Behaviorist .Nativist .Interactionist Solution 1). Behaviourist: This is proposed by the behavioural theorists Skinner. As per his theory, children imitate what they see and hear and all behaviour is acquired by learning, so it can be unlearned by either the positive reinforcement or negative reinforcement. Skinner proposed that the speech of children is shaped by adults by reinforcing the babbling of infants. 2). Nativist: Nativist Noam Chomsky proposed a “LAD”, Language Acquisition Device, and believed that children are born with certain innate skills of language learning, which determines their speed of learning. They can learn the native language at a high speed and can improve their grammatical skills without much effort. The same inheritance factor is responsible for the skill of learning multiple languages in certain people. 3). Interactionist: Lev Vygotsky described the concept of “zone of proximal development,” which explains how the children learn better from the other children, i.e. collaborative learning. School environment play an important role in improving the intellectual skills of the children by means of classroom teachings and also learning from the other children. Interaction with the other school children also influences the development of communication skills in the society. Children learn from the other children in a better way than do from the adults..

What are the six categories of concrete wall systems in current use? Solution 18) Bleeding in fresh concrete refers to the process where free water in the mix is pushed upward to the surface due to the settlement of heavier solid particles such as cement and water. Some bleeding is normal but excessive bleeding can be problematic. The way you work that bleed water can affect the durability of your products. The biggest factor in bleed water rates is the water-to-cement ratio. A higher ratio can lead to excessive bleeding. The cement type and fine aggregates can play a role in determining the bleed rate. The fewer fines you have in your mix, the more bleeding will occur. Factors also include concrete height and pressure. The relationship between bleed water and concrete heights starts off as linear, but eventually becomes nonlinear at increased heights. Ways to reduce bleeding in concrete include: 19) Portland cement is a basic cement mixture and a fundamental ingredient for many common cement applications. Because Portland cement is very common, it is also often called “Ordinary Portland Cement” or simply “OPC.” Since the early 20th century, Portland cement has been used internationally for a wide variety of applications including concrete projects, mortar pastes, stucco decorations, and grout fillings Roman cement was the predecessor to ordinary Portland cement. A crude form of Roman cement was rediscovered by English engineer John Smeaton in 1756. The formula for Roman cement was refined and patented in 1796 by James Parker. Around 1811, James Frost developed British cement: a new way of processing cement that became instrumental in making Portland cement. In 1824, the first form of Portland cement was patented by English cement manufacturer Joseph Aspdin. Aspdin’s version of Portland cement was further refined by his son, William, in 1843, and it closely resembled the ordinary Portland cement we know today. The United States imported Portland cement from Germany and England as early as 1868. Between the 1970s and 1980s, the United States began manufacturing their Portland cement in Michigan and Pennsylvania. Within a few years, most of the Portland cement used in the United States was produced locally. 20) For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals o.

Which members of the truss are zero-force members? Solution assuming all members to be weightless. at the joint E, the only force possible in the vertical direction is due to DE. so the vertical component of force in DE should be zero, because the joint E is at equilibrium. If the vertical component is zero means there is no force in that member; it is a pin jointed member and force will be along the bar and it is an inclined bar. if there is a horizontal component, there will be a vertical component. EF is a zero force member, because there is no force in x direction at E as discussed before. at joint D sum of forces along x direction should be zero. Since the DE is a zero force member, CD should also be a zero force member DF should also be a zero force member because at D both others are zero force members and there will be no member to offer reaction force. CF will have some force since it will have to compensate the vertical 10KN. and all other members will havesome force from there onwards. the values of force will depend on the lengths of the members. so the zero force members are CD, DE, DF, and FE.

Autotrophs depend on heterotrophs to oxidize sugar and release CO2 into the atmosphere. The majority of heterotrophs on Earth do not use aerobic respiration as a form of energy conversion. Heterotrophs evolved on Earth before autotrophs. The majority of autotrophs on Earth require aerobic respiration in order to survive. Heterotrophs are dependent on autotrophs to generate O2 from H2O in order to support aerobic respiration. Heterotrophs depend on autotrophs for conversion of light energy to chemical energy. There are no metabolic differences between autotrophs and heterotrophs. Heterotrophs that do not eat autotrophs every day will die in a short time. Autotrophs depend on heterotrophs to oxidize sugar and release CO2 into the atmosphere. The majority of heterotrophs on Earth do not use aerobic respiration as a form of energy conversion. Heterotrophs evolved on Earth before autotrophs. The majority of autotrophs on Earth require aerobic respiration in order to survive. Heterotrophs are dependent on autotrophs to generate O2 from H2O in order to support aerobic respiration. Heterotrophs depend on autotrophs for conversion of light energy to chemical energy. There are no metabolic differences between autotrophs and heterotrophs. Solution the correct statement would be : 4: because autotrophy is more complex than heterotrophy , the very first organisms were heterotrophs because they could feed on the molecules surrounding them. 6: Heterotrophs are dependent on autotrophs to generate O2 from H2O in order to support aerobic respiration. because if the autotrophs do not produce oxygen then heterotrophs can\'t live. infact the earth\'s atmosphere before autotrophs was without oxygen 7: Heterotrophs depend on autotrophs for conversion of light energy to chemical energy. similarly, heterotrophs never had the ability to convert sunlight into chemical energy. they only depended on autotrophs to produce food when the moleclar food was scarce..
