A) 9 B) 11
C) 13 D) 15
 
Answer & Explanation Answer: B) 11

Explanation:

Half the Product of Number in the upper & lower box gives the number in the middle box.

i.e. 18 x 4/2 = 36

15 x 6/2 = 45

In the same way 

8 x N/2 = 44 => N = 11.

Q:

Why are yeast cells frequently used as hosts for cloning?

A) they are eukaryotic cells B) they do not have plasmids
C) only yeast cells allow the gene to be cloned D) they easily form colonies
 
Answer & Explanation Answer: A) they are eukaryotic cells

Explanation:

If you were to produce a protein in bacterial cloning systems, you would not get the same post transcriptional and post translational modifications because the prokaryotic and eukaryotic systems work differently on the modifications.

Thus human recombinant protein genes are usually cloned in yeast cells. Also since they have a short generation time, they can be easily culture.

Q:

Are you certified in CPR, First Aid, and AED?

Answer

Here the intention of the interviewer is to know that whether you are certified medical assistant or not.


NOTE ::


Before the interview, be sure to check if your certifications are still valid. Remember that the Red Cross’s First Aid/CPR/AED certifications last for only 2 years, so it’s important to set a reminder to get re-certified after 2 years.


 


Sample Answer ::


First Aid, CPR, and AED training was part of my medical assistant training, and my Red Cross certifications are still valid for 20 more months. I understand that I need to take review courses every two years to get re-certified.

Q:

Q = mcdT refers to

A) Enthalpy formula B) Heat Transfer formula
C) Specific Heat formula D) Heat of Vaporization
 
Answer & Explanation Answer: C) Specific Heat formula

Explanation:

Q = mc∆T refers to Specific Heat formula.

 

When heat energy is added to a substance, the temperature will change by a certain amount.

The relationship between heat energy and temperature is different for every material, and the specific heat is a value that describes how they relate.

 

Q = mc∆T

 

Q = heat energy (Joules, J)

m = mass of a substance (kg)

c = specific heat (units J/kg∙K)

∆T = change in temperature (Kelvins, K)
