Recall that E. coli can grow in glucose-salts medium, which contains only glucose and a few inorganic salts. This means the glucose is serving what two purposes in the cell? Starting point from which all cell components are made Energy source Source of nitrogen A monosaccharide from that the cell can assemble into polysaccharides such as cellulose for its cell wall Source of phosphate Solution The answer is E.coli, mainly uses glucose as the energy source Escherichia coli is a heterotrophic organism, carbon is very important to E. coli because the bacterial cell is composed almost entirely of carbon molecules bound to other important elements. E. coli\'s main source of carbon comes from glucose molecules. This is then broken down into useable carbon by means of central metabolism, which consists of three steps: 1. Embden-Meyerhof-Parnas (EMP) Pathway: converts glucose to pyruvate 2. Tricarboxylic Acid (TCA) cycle: oxidizes Acetyl CoA to CO2 3. Pentose Phosphate Cycle (PPP): oxidizes glucose to CO2.

Question: Hello, I need some assistance in writing a java pr... Hello, I need some assistance in writing a java program using stacks (LIFO). Create a Calculator w/ GUI Write a program that graphically displays a working calculator for simple infix expressions that consist of: single-digit operands, the operators: +, -, *, and /, and parentheses. Make the following assumptions: unary operators (e.g. -2) are illegal all operations, including division, are integer operations (and results are integers) the input expression contains no embedded spaces and no illegal characters the input expression is a syntactically correct infix expression division by zero will not occur (consider how you can remove this restriction) Create a GUI application, the calculator has a display and a keypad of 20 keys, which are arranged as follows: C < Q / 7 8 9 * 4 5 6 - 1 2 3 + 0 ( ) = As the user presses keys to enter an infix expression, the corresponding characters appear in the display. The C (Clear) key erases all input entered so far; the < (Backspace) key erases the last character entered. When the user presses the = key, the expression is evaluated and the result appended to the right end of the expression in the display window. The user can then press C and enter another expression.

If you are monitoring a 1 V source on an oscilloscope and the scope measures the signal as 10 V, identify two possible causes. Solution Ans) One of the possible cause is the probe which connects 1 V source to oscilloscope is 10x probe ,which means it will give a gain of 10 ,because of that 1 V looks like 10 V in scope Another reason may be due to DC offset added because incorrect 0V position in the scope,adjusted by putting in GND.

following concepts from Johnson\'s book in Ch. 1, Ch. 2 or Ch. 3-- what are the aspects and definition of Moral Reasoning, Nature of harms, moral disengagement and moral imagination, what is shadow of Irresponsibility and the Shadow of Privilege? what are the basic characteristic traits of wisdom, diligence, humility? and how does Moral compass and golden rule relate to emotional and ethical intelligence as discussed by Weinstein and Maxwel? Solution Moral Reasoning Moral reasoning can be defined as the process in which an individual tries to find out what is right or wrong, taking into consideration personal postion, and with the help of logic. Every day epople ahve t use this concept and in several situation. Every day people have to ask several questions before taking into consideration various factors before telling a lie, that whether the lie outweighs its consequences. Moral disengagement Moral disengagement is a term used to define a process wherein one convinces that ethical standrds do not apply to the person in a particular situation, by separating moral standrads from the inhumane conduct. Moral imagination Moral imagination is a term which implies that men and women are human beings and that the power of imagination enables the human being to imagine beyond appearances, a heirarchy of worth and truth. Shadow of irresponsibility A leader can either be a shadow of light or a shadow o darkness. The laeder who is allous, corrupt, intoleran is a shadow of irresponsibility..

Explain how the structure and function are linked together for the following organs of the digestive system: 1) Mouth 2) Oesophagus 3) Stomach 4) Small intestine 5)Large intestine 6)Rectum 7) Anuss Solution I.Mouth: It is the first organ of the digestive system and food is first taken into the body via the mouth. It consists of tongue, teeth and saliva. These three elements work together to aid the procedure of swallowing. Teeth are used for the process of mastication to make the food smaller is size which is softened by the saliva and turned into bolus by the tongue for aiding the process of swallowing. Saliva is used for softening the food and digesting starch by the salivary amylase. Swallowing occurs bytwo involuntary actions - the soft palate, the back of the roof of the mouth, closes off the nasal cavity, and the epiglottis, a flap of cartilage, tilts downwards to seal the trachea. II.II. Oesophagus – the food passes through the throat and enters the food pipe or trachea. The walls of the oesophagus are muscular and elastic and helps propel the food towards the stomach by rhythmic muscular contractions called peristalsis. Just before the opening to the stomach is an important ring-shaped muscle called the lower esophageal sphincter (LES). This sphincter opens to let food pass into the stomach and closes to keep it there. LES prevents regurgitation. III.Stomach – the food is propelled into the stomach where it stays for upto five hours. The food along with the gastric juices of the stomach is converted to chyme by the churning action of the stomach walls. The stomach walls secrete strong acid (HCl) to make the food acidic in order for the enzyme pepsin to work. Pepsin is important for the breakdown of proteins. Once the contents of the stomach are properly processed they are released into the upper small intestine through the pyloric sphincter. IV.Small intestine – Small intestine is the longest organ of the digestive system and its composed of three segments called the Duodenum, Jejunum and ileum. The food is released into the duodenum from the pyloric sphincter where the pancreatic juices are released along with bile juice from the bile duct. The bile turns the food alkaline so that the pancreatic enzymes can process the food. These enzymes require a alkaline medium to digest the fats and lipids. Contents of the small intestine start out semi-solid, and end in a liquid form after passing through the organ. Water, bile, enzymes, and mucous contribute to the change in consistency. The duodenum is largely responsible for the continuous breaking-down process, with the jejunum and ileum mainly responsible for absorption of nutrients into the bloodstream. Once the nutrients have been absorbed and the leftover-food residue liquid has passed through the small intestine, it then moves on to the large intestine, or colon. The small intestine has a folded lining to absorb nutrients; the lining of the large intestine is flatter V.Large intestine -.

Describe the parts of the cytoskeleton and what role do they play. Suppose you get an infection, which element in the cytoskeleton is important in combating it and WHY? The answer must be in long paragraph form. Please be detailed. (Hint: the answer is linked to white blood cells) Solution The cytoskeleton is responsible for cell shape, motility of the cell as a whole, and motility of organelles within a cell. There are three types of filaments these are microfilaments, microtubules, and intermediate filaments Microfilaments form a band just beneath the plasma membrane that Microtubules participate in a wide variety of cell activities. Most involve motion. The motion is provided by protein \"motors\" that use the energy of ATP to move along the microtubule. There are several types of intermediate filament, each constructed from one or more proteins characteristic of it. III intermediate filament proteins of cells, including fibroblasts, smooth muscle cells, and white blood cells Intermediate filaments element in the cytoskeleton is important in combating infection it provide tensile strength to the cell. Vimentins are required for Endothelial transmigration - white blood cells leave the bloodstream to combat infection.

C. The lipid bilayers found in cells are fluid, yet asymmetrical in the composition of the monolayers. Is this a paradox? Explain your answer. D. Why do transmembrane domains of proteins typically fold into alpha helices or beta-barrels rather than exist as disordered chains? Solution C) The lipid bilayer is made up amphipathic lipid molecules, that is it contains a polar head (hydrophilic- water loving) and non- polar tails (hydrophobic). The polar heads face the aqueous envoriment and the tails towards the inside. An important property of the lipid bilayer is its fluidity . This property is due to the non-polar tails and is dependent on temperture and the lipid composition. Fludity in the bilayer helps in the movement of the molecules within the structure and in maintianing permeability. The two monolayers are asymmetrical in their structure as well as in function. The asymetrically nature of the layers is based on the different kinds of protiens found in the monolayers and their specific orientation in the membrane. This asymmetric nature helps cells to distinguish between the inner surface of the cell and the outer surface of the cell and plays an important role in the during apoptosis and other numerous cellular functions..
