Prokaryotic and eukaryotic cells Name three key differences (one for each of the following) 1. DNA 2. RNA 3. Cell organization Differentiate Gram positive and Gram negative bacteria. Solution 1. DNA Prokaryotes have small amount of DNA with no introns and few non functional regions. DNA is not bound by proteins and is naked.DNA is circular. Eukaryotes have large amount of DNA with introns and large amount of non functional regions. DNA is bound by histone proteins. DNA is linear. 2. RNA Prokaryotic RNA is polycistronic, ie; a single mRNA is transcribed by the several structural genes of an operon. Life span is short. Poly A tail is absent. Eukaryotic RNA is monocistronic, i.e; only one site for initiation and also termination of protein synthesis. Life span is longer. Poly A tail is present. 3. Cell organization Prokaryotes are usually unicellular with no cell organelles like endoplasmic reticulum, golgi apparatus and mitochondria. Nuclear membrane is absent. Eukaryotes are usually multicellular, but unicellular eukaryotes are also present like yeasts. THey have cell organelles like Endoplasmic reticulum, golgi apparatus and mitochondria. Nuclear membrane is present. Bacteria are classified as Gram positive and Gram negative based on the color they take up on performing Grams Staining. The differences between these two types of bacteria is due to the structure of cell wall. Gram positive bacteria remain purple in color in grams staining. The cell wall is made up of multiple layers of peptidoglycan. Teichoic acid is present. Cell wall is thicker but fewer varities of chemicals are present. Periplasmic space is absent. Gram negative bacteria get decolorised on treatment with acetone or alcohol and take up pink color when stained with grams staining. The cell wall is made up of very few layers of peptidoglycan, and large amount of lipopolysaccharide which acts as endotoxin. Teichoic acid is absent. THe cell wall is thinner compared to gram positive bacteria and has various types chemicals present. Periplasmic space is present. It also has outer membrane proteins..

What are the main functions of the components of prokaryotic vs. eukaryotic cells? Could either cell type survive without any of them? (Answer must be at least a page long, very detailed and in paragraph form please) Solution Prokaryotes are unicellular living beings that need organelles or other interior film bound structures . In this manner, they don\'t have a core, at the same time, rather, by and large have a solitary chromosome: a bit of roundabout, twofold stranded DNA situated in a territory of the phone called the nucleoid. Most prokaryotes have a cell divider outside the plasma film. Like a prokaryotic cell, an eukaryotic cell has a plasma film, cytoplasm, and ribosomes. Nonetheless, not at all like prokaryotic cells, eukaryotic cells have: a film bound core various film bound organelles (counting the endoplasmic reticulum, Golgi contraption, chloroplasts, and mitochondria) a few bar formed chromosomes Since an eukaryotic cell\'s core is encompassed by a film, it is regularly said to have a \"genuine core. \" Organelles (signifying \"little organ\") have specific cell parts, similarly as the organs of your body have particular parts. They permit diverse capacities to be compartmentalized in various territories of the cell. The piece of the cell divider varies altogether between the areas Bacteria and Archaea, the two spaces of life into which prokaryotes are separated . The structure of their cell dividers additionally varies from the eukaryotic cell dividers found in plants (cellulose) or organisms and bugs (chitin). The cell divider works as a defensive layer and is in charge of the life form\'s shape. A few microorganisms have a container outside the cell divider. Different structures are available in some prokaryotic species, yet not in others. For instance, the case found in a few animal types empowers the living being to connect to surfaces, shields it from lack of hydration and assault by phagocytic cells, and expands its imperviousness to our invulnerable reactions. A few animal categories likewise have flagella utilized for velocity and pili utilized for connection to surfaces. Plasmids, which comprise of additional chromosomal DNA, are likewise present in numerous types of microorganisms and archaea. Commonly, the core is the most conspicuous organelle in a cell. Eukaryotic cells have a genuine core, which implies the cell\'s DNA is encompassed by a layer. Thusly, the core houses the cell\'s DNA and coordinates the blend of proteins and ribosomes, the cell organelles in charge of protein union. The atomic envelope is a twofold layer structure that constitutes the furthest bit of the core. Both the internal and external layers of the atomic envelope are phospholipid bilayers. The atomic envelope is punctuated with pores that control the section of particles, particles, and RNA between the nucleoplasm and cytoplasm. The nucleoplasm is the semi-strong liquid inside the core where we discover the chromatin and the nucleolus. M.

Aneuploidy is the presence of an abnormal number of chromosomes in a cell.It can be monosomic or disomic or trisomic. Monosomy is lack of one chromosome of the normal complement.Monosomy of the sex chromosomes(45,X) causes Turner syndrome. Trisomy is the presence of three copies,instead of the normal two,of a particular chromosome.The presence of an extra chromosome 21,which is found in Down syndrome. Triploid is having three homologous sets of chromosomes..

If your organization is going to apply for a grant, when do you think, if ever, it would be appropriate to make the application public? What would be the benefits and drawbacks of doing it before the application is submitted? What about after? Solution Answer ) Grants in general term conside as money awards to organization to take care or start a social project .In real life, grant may be given in kinds other than cash ( travel expenses, data collection supports ,software, time off the job). and occasionally, mainly for research, it can be made to individuals. An organization apply for grant for many reason , like, times when we don\'t have much money to do excellent community work,Government is ready to give special funding for some unique projects, organization are asked to get some community work .and organization is well aware about its capability to meet the eligibility standards for such awards. If my organization is going to apply for a grant, it would be appropriate to make the application public once the purposal of grant get accepted by granting agencies . The schedule of disbursement of fund is out. Drawbacks of making public before application is submitted Benefits Diclosing after getting approved : Drawback s Benefits.

If the characteristic followed in the pedigree is x-linked recessive allele, what is III-1\'s genotype? a. Hemizygous for a dominant allele b. Hemizygous for a recessive allele c. Definitely heterozygous d. dominant e. Either heterozygous or homozygous dominant Solution 1st generation parents 1,2 though are normal but must be heterozygotes (Pp) since their children are affected i.e. 2nd generation males 1,3. Since 1st generation male 3 is affected (pp) and 4 is normal but regardless if 4 in 1st generation is PP or Pp their children will be either 4 Pp i.e. heterozygote or 2 affected pp and 2 heterozygotes Pp. But the 2nd generation 4, 5 female are normal but heterozygotes Pp. So the cross between a 2nd generation affected male 3(pp) and a normal but heterozygote female 4(Pp) would have a normal male child only if hemizygous for a dominant allele condition exists. Hemizygous is a condition in which only one gene copy/DNA sequence exists in diploid cells. Males are hemizygous for most genes on sex chromosomes since they have only one X and one Y chromosome unlike two X for females. A recessive X-linked gene requires two mutant alleles to affect the female phenotype. Rules followed here are.

How and when do we learn ethics? How and when do we learn ethics? Solution Ethics is actually a branch of philosphy. It guides us about right conduct and wrong conduct. Directly or indirectly everyone is learning ethics from childhood. Children are taught to avoid doing wrongs by parents from very tender age onwards. General ethics should be started from early ages so as to make the child behave in the society in a presentable manner. Professional ethics, conduct to certain profession or group can be learnt after selecting that profession..

How does a dominant culture differ from a subculture In your answer.pdf

aroraenterprisesmbd

How does a dominant culture differ from a subculture? In your answer be sure to define both terms. Solution Organizations are, in a way, small or large ecosystems, within which its members interact under certain codes of conduct. Organizational culture is then all these formal and informal rules which take the members of the organization to establish and accepted behaviors that generate disapproval, and in general, the expected behavior of each of the members. Recent studies have found that, generally, there is a culture that is identified as dominant, because most of the members of the organization accept and follow it. However, it is also true that the dominant culture is not homogeneously accepted by all members, some of them create rules and codes as a reaction to it, thus forming more specific subcultures. Thus, the dominant culture revolves around the core values of the organization or that group of people in particular, and are widely shared. Instead, subcultures go around problems, experiences or specific realities of a smaller group of people, values are not massive, but share few people in response to specific situations, such as a high school subculture or Latinos African Americans. In the dominant culture deprive the philosophical values that inspire the masses, in the subculture specific needs of this group are imposed, it is more pragmatic, that is a fundamental difference..

Each letter in the word Massachusetts is written on a card. The card.pdf

aroraenterprisesmbd

Each letter in the word Massachusetts is written on a card. The cards are placed in a basket. What is the probability of selecting two S\'s if the first card is replaced before selecting the second card? Solution It\'s a probability of 16 out of 169. There are 13 letters in MASSACHUSETTS. 4 of the 13 are the letter S, so there is a 4 in 13 chance to draw an S. Since the first card is replaced, there is still a 4 in 13 chance of drawing another S. So the combined probability is 4/13 x 4/13 = 16/169.

Below is the question I need help with. It need to be done in Java. I need help making the priority queue part of the assignment, if you can add the GUI it will be helpful. You are to simulate a dispatcher using a priority queue system. New processes are to be entered using a GUI with priority included (numbering should be automatic). Processes are also to be terminated by GUI command. Context switches are to be by command with the cause of the switch being immaterial. Assume only one CPU. Priorities and numbers of processes can be kept small, just big enough to demonstrate the below listed functionality. You may pre-populate the queues initially from a data file. I am looking at the mechanism as you are NOT creating actual processes, just simulating them. Functionality to be provided by you: 1. Priority based Ready Queue(s). 2. Blocked list. 3.

Case study Job Satisfaction in the Banking Industry Or the logisti.pdf

aroraenterprisesmbd

Case study: Job Satisfaction in the Banking Industry: Or the logistical nightmare of conducting large scale quantitative research Job characteristics are believed to have an impact on stress and well-being at work (Karasek& Theorell, 1990). The demands of the job on the one hand and theextentto which you have control over your own activities (decision latitude) on the other, are two factors which together define how stressful a job is. Those jobs which are high demand, but offer limited control, are considered to be high-strain and carry an increased risk of job dissatisfaction, stress and burnout. Based on this theoretical framework, the Union of Belgian Banks sent out a research call to several institutions, with a bidding process based on criteria such as quality of the proposal, timing, and – above all – budget. The aim of the research was to carry out quantitative research to measure the relationship between job characteristics and job satisfaction in all Belgian banks (seeCambréet al., forthcoming). But in order to do this effectively, several methodological issues needed to be resolved during the research process. First of all, aresearch consortiumwas selected to conduct the research, or more precisely, the two highest ranked bidders were asked to jointly undertake the research. This was the outcome of a political decision by the banks (see also p. 142, ‘Affiliation and conflicts of interest’),since the employers preferred one partner and the unions (employee representatives) preferred the other. The two competing research institutes, a private company specialising in stress at work and theKatholiekeUniversiteitLeuven (Belgium), were required to co-operate and develop a level of trust in order to conduct the research. For example, both research institutes had different ideas as to which scale should be used in the questionnaire. They could not just combine the scales or include both scales, simply because they are supposed to measure the same concept. Furthermore, this would also make the questionnaire too complex. Therefore, the research institutes had to combine their knowledge, look for compromises and jointly work on a shared vision, which is, to say the least, rather time consuming. A second obstacle that needed to be overcome was thesample(see Chapter 7). Intotal, 69,000 employees work for Belgian banks and it was decided that questioning all employees would be too complicated and too expensive. Therefore the research committee, consisting of representatives of the banks, the unions and the research consortium, opted for a cross-sectional design (p. 45) with a fixed sample of 15,000 employees (roughly 21%; see p. 187 ‘Absolute and relative sample size’). In this sample, the small banks were over-represented in order to be able to make conclusions at the level of each bank. Within each bank, the respondents were selected at random with no particular quota for gender, age or employee level. In the postal survey (see p.231 ‘Self- co.

why does countercurrent flow yields greater oxygen uptake than concu.pdf

aroraenterprisesmbd

why does countercurrent flow yields greater oxygen uptake than concurrent flow? Mention diffusion. Solution Answer: The orientation of medium is perpendicular to the flow of blood in countercurrent flow so that it is leading to higher efficiency of oxygen diffusion to medium flow at differential points whereas in concurrent flow, medium is synchronous and parallel to the flow of blood so that the rate of diffusion from the alveoli to blood capillaries are lower. The both bloodstreams are going to move in a similar or simultaneous pathway. The concurrent flow yields intermediate in transfer efficiency with multivillous oxygen diffusion main found in humans and sheep.
