10. The push button is pushed to the second stop when we pipette out or transfer the sample, and to completely void the sample without leaving any sample in the pipette tips 11. The button is to be released after it is withdrawn from the solution/liquid. If it is released prior to withdrawal, the solution reenters the pipette tip. 12. If the push button is pressed to the second stop and is released even before the pipette tip is withdrawn from the solution, the solution enters the pipette. 13. When concentrations or dilutions of the sample that are to be transferred changes, when different solutions or chemicals are transferred, when containment is required, tips need to be changed with each transfer. 14. The fragments obtained will have blunt ends if the restriction enzyme cuts at the center. Yes. They are still useful because linkers or adapters can be attached to the blunt end to make them useful. Moreover, new restriction sites can be created by attaching linkers or adapters. 15. Yes it can be done. The restriction enzyme creates the same overhanging ends since it recognizes the same restriction site in both the DNA. Therefore, the two different DNA can basepair at the sticky ends. Solution 10.

1. Working capital is the capital that a company uses for its day to day operations. Working capital is computed using the formula: Working capital = current assets – current liabilities. 2. Determinants of working capital requirements are – nature of business, seasonality of operations, production policy, market conditions and conditions of supply. A service company will have a lower working capital requirement than a manufacturing company. Firms with seasonality in operations will have higher fluctuations with regards to their working capital requirements. Market conditions in the form of degree of competition will affect working capital requirements. Higher competitive pressure will increase working capital requirements. 3. Three major decisions that managers have to take while performing the finance function are: (i) Investment decision – Managers have to select those assets that the business will invest in. It is also known as capital budgeting decisions. (ii) Financing decision – These decisions pertain to determining how the total funds that are required for the business will be obtained – will it be through debt or equity or a mix of debt or equity. (iii) Dividend decision – This pertains to determining what quantum of earnings should be distributed to shareholders as dividends and what quantum should be retained for meeting future growth requirements of the company. 4. Financial management involves planning, directing, monitoring and controlling the monetary resources of a company in such a manner that the goals and objectives of the company are achieved in an efficient manner. It involves management of capital budgeting, capital structure, working capital management, etc. Financial management is important as it helps an organization to set clarity towards its financial goals and helps in efficient utilization of resources. 5. Cash flow is not a suitable judge of profitability as it merely shows the changes in cash position of a firm in a financial year from its operating activities, from its financing activities and from its investing activities. Cash flow statement does not help us to determine gross profit margins, operating profit margins and net profit margins. We can just gauge the reason for changes in cash position in a year. 6. Financial risk refers to all kinds of risk associated with a financial transaction and an investment transaction. It can be in the form of credit risk, asset backed risk, investment risk etc. These risks arise due to the fact that there is a probability of loss that is inherent in any financing and investment method and this probability of loss cannot be avoided.

The answer to this question is (E) If you look at N2, you can see that as 2 moles of N2 is formed 4 moles of NH3 is reacting. Thus, since the rate of formation of N2 is 2.0 mol/(L*s), the rate of formation of NH3 is double that (2*2.0mol/(L*s))=4.0 mol/(L*s). I hope this helped!

It is a molecular process involving the exchange of bonds between the two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. This is represented by the general reaction scheme: AX + BY ? BX + AY These chemical species can either be ionic or covalent. When referring to precipitation reactions between solutions of ions in inorganic chemistry, these were formerly referred to as double displacement or double replacement reactions, and these terms are still encouraged. It seems that the term double decomposition is more specifically used when at least one of the substances does not dissolve in the liquor, as the ligand or ion exchange takes place in the solid state of the reactant, i.e. AX(aq) + BY(s) ? AY(aq) + BX(s). Types: Neutralization A neutralization reaction is a specific type of double displacement reaction. Neutralization occurs when an acid reacts with an equal amount of a base. A neutralization reaction creates a solution of a salt and water. For example, hydrochloric acid reacts with sodium hydroxide to produce salt and water: HCl (aq) + NaOH (aq) ? NaCl (aq) + H2O (l) Aqueous metathesis (precipitation) Metathesis reactions can occur between two inorganic salts when one product is insoluble in water, driving the reaction forward. For example, the precipitation of silver chloride from a mixture of silver nitrate and sodium chloride causes sodium nitrate to be left in solution: AgNO3 (aq) + NaCl (aq) ? AgCl (s) + NaNO3 (aq) The formation of an insoluble gas that bubbles out of the solution, or a molecular compound such as water, also drives the reaction to completion. Therefore, a solubility chart (or general knowledge of solubility rules) can be used to predict whether two aqueous solutions will react. HSAB theory can also be used to predict the products of a metathesis reaction. Aqueous metathesis (double decomposition) The reactants need not to be dissolved for metathesis reactions to take place. An example of this is the formation of barium thiocyanate when boiling a mixture of copper(I)thiocyanate and barium hydroxide in water: Ba(OH)2 (s) + 2 CuCNS (s) ? Ba(CNS)2 (aq) + 2CuOH (s) Acid and carbonates A subcategory of aqueous metathesis reactions is the reaction of an acid with a carbonate or bicarbonate. Such a reaction always yields carbonic acid as a product, which spontaneously decomposes into carbon dioxide and water. The release of carbon dioxide gas from the reaction mixture drives the reaction to completion. For example, a common, science-fair \"volcano\" reaction involves the reaction of acetic acid with sodium bicarbonate: HCH3COO (aq) + NaHCO3 (s) ? NaCH3COO (aq) + CO2 (g) + H2O (l) Solution It is a molecular process involving the exchange of bonds between the two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations.

From the LCAO method: The overlap of the 1s AO on one H atom with the is AO on a second gives one bonding MO (s) at lower energy to the constituent AOs and one antibonding MO (s*) at higher energy. Each MO can hold 2 e-. H2^- has 3e- and so the MO \"scheme\" is s(2e-) s*(1e-) Bond Order = ½[S (bonding e-) - S (antibonding e-)] = ½[2-1] = 0.5 so H2^2- is predicted to be bonding. When irradiated with UV light an e- in the s MO is promoted to the s*: s(2e-) s*(1e-) ? h? ? s(1e-) s*(2e-) ? dissociation The bond order of the excited state is formally ½[1-2] = -0.5 which is repulsive: the species flies apart into H^- and H. (H atom not a period). You have to look at an MO diagram for O2; if you do that, focusing on the p-based orbitals, you\'ll see that there are 6 bonding electrons (2 in the p-sigma orbital, and 4 in the p-pi orbitals), and two electrons in the p-pi* (one in each). Thus there are six bonding electrons and two antibonding electrons, so the net is four bonding electrons. Since it takes two bonding electrons to make a bond, the bond order is 2 for O2. If you take away one of the antibonding electrons, now you have a net of five bonding electrons, which - when divided by 2 - gives you a bond order of 2.5. Because you\'ve taken away one electron from neutral O2, the charge will be +1.

Cis-trans isomers occur because it is impossible to rotate the double bond without breaking it. Thus, isomers that are related by \"rotation\" about the double bond are actually separate compounds - cis/trans isomers. In the example you have drawn, keep the -CH2CH3 group and the right-hand H in place and reverse the position of the -CH2CH2CH3 group and the other H (so that the H\'s are on \"opposite\" sides of the double bond). This is the trans isomer of the compound you drew (you have the cis isomer). Now, imagine that instead of the CH2CH2CH3 group you had another H. In that case, switching the position of the two H\'s would result in the same compound, and cis-trans isomers would not be possible. In general, cis/trans isomers are possible only if each carbon that is part of the double bond is bonded to two DIFFERENT groups. This is only true for I and III. In II, the right-hand carbon of the double bond is bonded to two H\'s. And in IV, the left hand carbon of the double bond is bonded to two - CH3 groups. Thus neither of these has cis-trans isomers.

When a heterozygote (Aa) is not an exact intermediate between the two homozygotes (AA and aa), then not all of the genetic variance in the population can be accounted for by differences in the average effect of the A and a alleles. In this case, the total genetic variance of the population can be subdivided into two components: Additive Genetic Variance (sa2): Genetic variation attributed to average differences between different allelic characters. Dominance Genetic Variance (sd2): Variance due to heterozygotes not being exact midpoints of homozygote parents. So that, Sg2 = Sa2 + Sd2 And now, total phenotypic variance can be rewritten as: Sp2 = Se2 + Sg2 = Se2 + Sa2 + Sd2 From this, we can define a new kind of heritability: Heritability in the narrow sense (h2):Proportion of phenotypic variance due to additive genetic variance alone h2 = Sa2 / Sp2 = Sa2 / Se2 + Sg2 = Sa2 / Se2 + Sd2 + Sa2 The greater h2 is for a population, the greater the fraction of the difference between selected parents and the population as a whole that will be preserved in the offspring of those parents. ______________________________________________________________ To see why it is h2 that matters for response to selection, consider an extreme case: 2 homozygotes are equal in phenotype, say with a value of 20. (AA=aa=20) But the heterozygote is overdominant, maybe with a value of 24. (Aa=24) So for this population, there is only dominance variance, and no additive genetic variance because there is no average difference between the carriers of a alleles and the carriers of A alleles. Now suppose that the population mates randomly and the genotype proportions are: If only individuals with the highest values were selected to breed, all parents would be heterozygotes. Offspring of heterozygotes would exactly reproduce the 1:2:1 distribution of genotypes seen in the parental generation. Thus, there would be no change in genetic composition of the F1 generation, despite the fact that there is genetic variation in the population. So, selection proves to be ineffective when all variance is due to dominance and there is no additive variance. It is important to consider that dominance variance arises from more than just the deviation of heterozygotes from the exact midpoint of homozygotes. Dominance variance (sd2) is considered to be any genetic variation that cannot be explained by average allelic differences, or additive genetic variance (sa2) For example, if a trait is affected by multiple loci then any epistatic interactions between the loci will appear as variance not associated with additive variance. In theory, this interaction variance (si2) could be separated from dominance variance (sd2). In practice, however, it is not possible to achieve accurate measures of separating these two parameters so all nonadditive variance is attributed to dominance variance (sd2). _____________________________________________________________________________ ________________ Important Mess.

It is a molecular process involving the exchange of bonds between the two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations. This is represented by the general reaction scheme: AX + BY ? BX + AY These chemical species can either be ionic or covalent. When referring to precipitation reactions between solutions of ions in inorganic chemistry, these were formerly referred to as double displacement or double replacement reactions, and these terms are still encouraged. It seems that the term double decomposition is more specifically used when at least one of the substances does not dissolve in the liquor, as the ligand or ion exchange takes place in the solid state of the reactant, i.e. AX(aq) + BY(s) ? AY(aq) + BX(s). Types: Neutralization A neutralization reaction is a specific type of double displacement reaction. Neutralization occurs when an acid reacts with an equal amount of a base. A neutralization reaction creates a solution of a salt and water. For example, hydrochloric acid reacts with sodium hydroxide to produce salt and water: HCl (aq) + NaOH (aq) ? NaCl (aq) + H2O (l) Aqueous metathesis (precipitation) Metathesis reactions can occur between two inorganic salts when one product is insoluble in water, driving the reaction forward. For example, the precipitation of silver chloride from a mixture of silver nitrate and sodium chloride causes sodium nitrate to be left in solution: AgNO3 (aq) + NaCl (aq) ? AgCl (s) + NaNO3 (aq) The formation of an insoluble gas that bubbles out of the solution, or a molecular compound such as water, also drives the reaction to completion. Therefore, a solubility chart (or general knowledge of solubility rules) can be used to predict whether two aqueous solutions will react. HSAB theory can also be used to predict the products of a metathesis reaction. Aqueous metathesis (double decomposition) The reactants need not to be dissolved for metathesis reactions to take place. An example of this is the formation of barium thiocyanate when boiling a mixture of copper(I)thiocyanate and barium hydroxide in water: Ba(OH)2 (s) + 2 CuCNS (s) ? Ba(CNS)2 (aq) + 2CuOH (s) Acid and carbonates A subcategory of aqueous metathesis reactions is the reaction of an acid with a carbonate or bicarbonate. Such a reaction always yields carbonic acid as a product, which spontaneously decomposes into carbon dioxide and water. The release of carbon dioxide gas from the reaction mixture drives the reaction to completion. For example, a common, science-fair \"volcano\" reaction involves the reaction of acetic acid with sodium bicarbonate: HCH3COO (aq) + NaHCO3 (s) ? NaCH3COO (aq) + CO2 (g) + H2O (l) Solution It is a molecular process involving the exchange of bonds between the two reacting chemical species, which results in the creation of products with similar or identical bonding affiliations.

From the LCAO method: The overlap of the 1s AO on one H atom with the is AO on a second gives one bonding MO (s) at lower energy to the constituent AOs and one antibonding MO (s*) at higher energy. Each MO can hold 2 e-. H2^- has 3e- and so the MO \"scheme\" is s(2e-) s*(1e-) Bond Order = ½[S (bonding e-) - S (antibonding e-)] = ½[2-1] = 0.5 so H2^2- is predicted to be bonding. When irradiated with UV light an e- in the s MO is promoted to the s*: s(2e-) s*(1e-) ? h? ? s(1e-) s*(2e-) ? dissociation The bond order of the excited state is formally ½[1-2] = -0.5 which is repulsive: the species flies apart into H^- and H. (H atom not a period). You have to look at an MO diagram for O2; if you do that, focusing on the p-based orbitals, you\'ll see that there are 6 bonding electrons (2 in the p-sigma orbital, and 4 in the p-pi orbitals), and two electrons in the p-pi* (one in each). Thus there are six bonding electrons and two antibonding electrons, so the net is four bonding electrons. Since it takes two bonding electrons to make a bond, the bond order is 2 for O2. If you take away one of the antibonding electrons, now you have a net of five bonding electrons, which - when divided by 2 - gives you a bond order of 2.5. Because you\'ve taken away one electron from neutral O2, the charge will be +1.

Cis-trans isomers occur because it is impossible to rotate the double bond without breaking it. Thus, isomers that are related by \"rotation\" about the double bond are actually separate compounds - cis/trans isomers. In the example you have drawn, keep the -CH2CH3 group and the right-hand H in place and reverse the position of the -CH2CH2CH3 group and the other H (so that the H\'s are on \"opposite\" sides of the double bond). This is the trans isomer of the compound you drew (you have the cis isomer). Now, imagine that instead of the CH2CH2CH3 group you had another H. In that case, switching the position of the two H\'s would result in the same compound, and cis-trans isomers would not be possible. In general, cis/trans isomers are possible only if each carbon that is part of the double bond is bonded to two DIFFERENT groups. This is only true for I and III. In II, the right-hand carbon of the double bond is bonded to two H\'s. And in IV, the left hand carbon of the double bond is bonded to two - CH3 groups. Thus neither of these has cis-trans isomers.

Oxidation means loss of electrons. Metals are electropositive and lose electrons easily to form positively charged ions with stable octet structures, thus they tend to be oxidized. Reduction means gain of electrons. Non-metals are electronegative and gain electrons easily to form negatively charged ions with stable octet structures, thus they tend to be reduced. Solution Oxidation means loss of electrons. Metals are electropositive and lose electrons easily to form positively charged ions with stable octet structures, thus they tend to be oxidized.

Progress in understanding the molecular basis of primary neurulation has occurred on two fronts: neural induction and shaping and bending of the neural plate. In regard to the former, the neural plate is now known to be the default state of the ectoderm, and induction of the neural plate actually involves suppressing the formation of the epidermal ectoderm (neural induction is not considered further herein). In regard to shaping and bending of the neural plate, about 100 mutations in the mouse have been identified that result in defective shaping and/or bending and, consequently, result in neural tube defects (NTDs); thus, these mutations provide insight into which genes are involved in both normal and abnormal neurulation. Because these form-shaping events of neurulation are driven by changes in cell behavior, as discussed earlier, it is not surprising that mutation of cytoskeletal, extracellular matrix/cell adhesion, cell cycle, and cell death genes results in NTDs. Neurulation is a highly choreographed morphogenetic series of events that must be precisely timed and coordinated across multiple tissues. This presumably involves signaling among tissues. It is the hope of studies using mouse mutations that such signaling pathways will be identified, ultimately leading to an understanding of the molecular basis of neurulation and the formation of NTDs in both animal models and ultimately in humans. In the following sections, we discuss what has been learned about the molecular basis of shaping and bending of the neural plate.Embryology Neurulation is the critical morphogenetic event occurring during the fourth week of human gestation, converting the previously developed neural plate into the ectoderm covered neural tube that will eventually differentiate into the brain and spinal cord. Genetic regulation of the events involved in mammalian neural tube morphogenesis is a complicated process that involves a multitude of genes. These genes have vital functions in a range of biological activities that are thought to include signaling molecules, transcription proteins and factors, cytoskeletal and gap junction proteins, growth factors, and tumor suppressor genes (Copp et al., 2003; Ewart et al., 1997; Sah et al., 1995; Zhang et al., 1996). The neural tube, formed by the cell shape changes and movements, ultimately fuses at several discrete points.Neurulation (or primary neurulation) starts in the fourth week of gestation and is the process that leads to the formation of the neural tube from the neural plate, the rudiment of the CNS [34]. It encompasses four essential and overlapping events: (1) neural induction, (2) shaping, (3) bending of the neural plate, and (4) closure of the neural tube. Neural induction (1) is the process of neural plate formation, that is, the beginning of the development of the CNS. It occurs during gastrulation starting on day 18. As described earlier, cells of the ectoderm differentiate into the neuroectoderm, a pseudostratif.
