Answer:
Misdiagnosis
Explanation:
If you do not have a complete medical file, you can misdiagnose the patient.
Answer:
False.
Explanation:
Zwitter ion may be defined as the molecule that contains the net neutral charge. The change in pH can change the charge on the zwitter ions. Amino acids can exist in the form of zwitter ions.
The basic environment, causes the deprotonation of the ammonia group. The carboxyl end of a protein release the hydrogen ions in the acidic environment , not in the basic environment.
Thus, the answer is false.

Answer:
500 mg Ampicillin
Explanation:
given data
molecular weight = 349 g/mole
need = 10 ml of a 1000 x solution
solution
we get here for 50 μg / mL
here 10 ml of a 1000 x solution
so here need to weight is =50 μg × 10 = 500μg
so we were to prepare 1000 x
so here we get weight that is
we should weight = 500μg × 1000
so it is = 500 mg / 10 mL
Answer: B) The number of electron in its valence shell.
Explanation:
Outermost electrons of the atoms which can participate in the chemical bond formation is known as valence electrons.
Atoms either transfer or share its valence electrons during chemical bond formation. Atoms transfer or share electrons to attain octet or in other words stability.
Generally, 8 electrons are required in their outermost shell or valence shell in order to attain stability. This rule is known as octet rule.
For example, general electronic configuration of sodium belonging to group 1 is 1s2 2s2 2p6 3s1.
No. of valence electrons in Na = 1
by loosing 1 electron, its outer shell electronic configuration become = 1s2 2s2 2p6 (Octet)
Hence, sodium and other group 1 elements are very reactive.
Similarly, halogens (ns2 np5) by gaining 1 electron attain octet (ns2 np6). Hence halogens are also very reactive.
Carbon atom belonging to group 14 has 4 valence electrons (ns2 np2) and share all 4 valence electrons to attain octet and hence reactive.
Nobel gases have octet in their outermost shell (ns2 np6), hence they are most nonreactive element.
