When doing medical research with human subjects, which four limitations are unavoidable?
Fofino [41]

Answer:

Answer

The limitations are-

1. Privacy of the individuals involved in the research process.

2. Physical and psychological risks should be minimized

3. The subjects should be chosen equitably

4. Only reasonable exposure to risks is admissible.

Explanation

The privacy of the individuals involved in the research must be taken into consideration. This will ensure safety of patient data and information. The risk of physical and physiological well being of the person must be taken into consideration in such a research. In addition to that, the subject must be made to understand every procedure and the risks involved before testing. Moreover, only minimal exposure to risks is allowed and must have been previously tested in animals to avoid deaths.

A chermist weighs out 400.0 g of Ca How many moles of Ca is this?
ra1l [238]

Answer:

<h3>The answer is 0.1 mol</h3>

Explanation:

To find out the number of moles we use the formula

n =  \frac{m}{M}  \\

where

n is the number of moles

M is the molar mass

m is the mass of the substance

From the question

m = 400 g

M of Ca = 40 g/mol

We have

n =  \frac{40}{400}  =  \frac{1}{10}  \\

We have the final answer as

<h3>0.1 mol</h3>

Hope this helps you

During transpeptidation, nucleophilic attack occurs between the α-amine group in the ____ site and the esterified carbon in the
kobusy [5.1K]

During transpeptidation, nucleophilic attack occurs between the α-amine group in the A site and the esterified carbon in the P site

<h3>What is transpeptidation ?</h3>

A chemical process in which an amino acid residue or peptide residue is transferred from one amino compound to another. This process occurs when a protease reversibly converts one peptide to another.

  • a process where one or more amino acids are transferred from one peptide chain to another, as in the case of a transpeptidase activity, or where a peptide chain itself is produced, as in the case of the production of a bacterial cell wall.
  • Peptidoglycan glyco-syltransferases create the glycan strands (PGTs). The most popular class of antibiotics' fatal targets are enzymes termed transpeptidases (TPs), which produce the peptide crosslinks: using beta-lactams

Chadwick's experimental work on the atom led to a better understanding of isotopes.
Vedmedyk [2.9K]

Chadwick discovered the existence of neutrons which accounts for isotopy.

Isotopes exists because atoms of the same element may differ in the number of neutrons present in each one. This phenomenon is called isotopy.

Chadwick discovered the existence of isotopes by bombarding Beryllium with alpha particles obtained from Polonium decay.

The discovery of the existence of neutrons led us to the a better understanding of isotopes since isotopes differ only in the number of neutrons present.
