Answer:

Hi there!

Your answer is:

Ethical concerns dictate everything about scientific research. They determine what can be researched, who it can be researched on, how the data will be presented, how long the subjects can be researched, and more. To get a research study approved by the Institutional Review Board, you need to abide by strong ethical codes. In conclusion, a researchers ethical standings determines everything about their study.

Hope this helps

There are a number of ethical principles that should be taken into account when performing undergraduate and master's level dissertation research. At the core, these ethical principles stress the need to (a) do good (known as beneficence) and (b) do no harm (known as non-malfeasance). In practice, these ethical principles mean that as a researcher, you need to: (a) obtain informed consent from potential research participants; (b) minimise the risk of harm to participants; (c) protect their anonymity and confidentiality; (d) avoid using deceptive practices; and (e) give participants the right to withdraw from your research. This article discusses these five ethical principles and their practical implications when carrying out dissertation research.

When you look at these five basic ethical principles, it may appear obvious that your dissertation should include these. However, there are many instances where it is not possible or desirable to obtain informed consent from research participants. Similarly, there may be instances where you seek permission from participants not to protect their anonymity. More often than not, such choices should reflect the research strategy that you adopt to guide your dissertation.

Broadly speaking, your dissertation research should not only aim to do good (i.e., beneficence), but also avoid doing any harm (i.e., non-malfeasance). Whilst ethical requirements in research can vary across countries, these are the basic principles of research ethics. This is important not only for ethical reasons, but also practical ones, since a failure to meet such basic principles may lead to your research being (a) criticised, potentially leading to a lower mark, and/or (b) rejected by your supervisor or Ethics Committee, costing you valuable time. In the sections that follow, we discuss the five of the main practical ethical principles that stem from these basic principles. Each of these basic principles of research ethics is discussed in turn:

Answer:

magnesium= +2

aluminum= +3

phosphorous= -3

lithium= +1

fluorine= -1

Explanation:

As fluorine having seven valance electrons in its outer most shell with atomic number nine. And for completing its outer most shell it needs one more electron that is why it form ion of -1 value.

Now  Aluminum has three electrons in its outer most shell with atomic number 13. So it need to lose these three electrons in order to be in stable state that is why it have ion in +3 state.

Same rule apply for other elements too.

What is the chemical equation for the alpha decay of erbium-144
iren [92.7K]

Answer:

Er-144 -------> Dy-140 + He-4

Explanation:

Alpha decay is the release of a hydrogen nucleus.  So the original atom will decrease the mass by 4 and the atomic number by 2.

A flask has a mass of 78.23g when empty and 593.63g when filled with water.When the same flask is filled with concentrateds ulfu
butalik [34]

Answer:

Density of concentrated H2SO4 = 1.99g/cm^3 = 1991.79Kg/m^3

Explanation:

mass of empty flask = 78.23g mass of flask filled when with water = 593.63g.

mass of flask filled when with concentrateds sulfuric acid, H2SO4 = 1026.57g

Mass of water = (mass of flask filled when with water) -

(mass of empty flask) = 593.63g - 78.23g = 515.4g

Volume of flask = volume of water = volume of concentrateds sulfuric acid, H2SO4 =

(mass of water)/ density of water) = 515.4g/1.00g/cm^3 = 515.4cm^3

The density of concentrated sulfuric acid is given by

Density of concentrated H2SO4 = (mass of H2SO4) ÷ (volume of H2SO4) = 1026.57g/515.4cm^3 = 1.99g/cm^3 = 1991.79Kg/m^3

Knowing that the protease shows highest activity between pH 4-6, what could be the identity of the base residue acting as a in t
olga_2 [115]

hey there!:

A) Knowing theatre the protease is showing the highest activity at pH 4-6, implies that the amino acid that amino acid that it is acting in is an amino acid with a basic side chain. Therefore, the residues can be any one of the three basic amino acids being histidine, arginine or lysine , having basic side chains at neutral pH.

b) The mechanism of reaction of cysteine proteases is as follows:

 First step in the reaction is the deprotonation of a thiol in the cysteine proteases's active site by an adjacent amino acid with a basic side chain, which might be a histidine residue. This is followed by a nucleophilic attack by the anionic sulfur of the deprotonated cysteine on the substrate carbonyl carbon.

Here, a part of the substrate is released with an amine terminus, restoring the His into a deprotonated form, thus forming a thioester intermediate, forming a link between the carboxy-terminal of the substrate and cysteine, resulting in thiol formation. Thus the name thiol proteases. The thioester bond is then hydrolyzed into a carboxylic acid moiety while again forming the free enzyme.

C) cysteine proteases have a pka of 8-9 but when they are deprotonated by a His residue, their pka would come down to 6-8, which would be their optimal pH for functioning. This is because there is a deprotonation of the thiol group , later restoring the HIS deprotonated form and then formation of a thioester bond. This thioester bond when hydrolysed will a carboxylate moeity , which is responsible for bringing the pH down towards a more acidic side.  

d) at the optimal pH , the fraction of deprotonated cysteine and protonated B will be equal which will change with the change in pH.

Hope this helps!
