A microbiologist was surprised when he could not recover Helicobacter pylori from gastric biopsies in which organisms were seen in the tissue sections. He was advised to switch from the Campy BAP selective medium to Skirrow's blood agar because the latter is free of cephalothin.

  • A broad-spectrum cephalosporin antibiotic called cephalothin is used to treat severe bacterial infections in the urinary tract, skin, bones, and lower respiratory tract.
  • A beta-lactam, first-generation cephalosporin antibiotic with bactericidal activity, cephalothin is semi-synthetic.
  • Penicillin-binding proteins (PBP) on the inner membrane of the bacterial cell wall are bound by cephalothin and rendered inactive.
  • PBPs take involvement in the last phases of bacterial cell wall construction as well as the remodeling of the cell wall during cell division.
  • PBP inactivation hinders the cross-linking of peptidoglycan chains, which is essential for the strength and stiffness of bacterial cell walls.

all plants give out oxygen during day and carbon dioxide during night. Do you agree with this statement. Give reason
Citrus2011 [14]

This statement is incomplete.

"All plants give out oxygen during day and carbon dioxide during night"

Explanation :

Photosynthesis occurs only during day time.

During this time oxygen is produced . Some oxygen is used for respiration and rest of oxygen is diffused out into air.

Carbon dioxide produced during day time by respiration is used in photosynthesis.

But at night time, no photosynthesis occurs  and hence no oxygen is produced oxygen from air diffuses into leaves to carry out respiration and carbon dioxide produced by respiration diffuses out into air.

Hence Respiration occurs day and night .. Hence Carbon dioxide  is emitted  all the time....

Predict what the results would be if mrna were radioactively labeled instead of polypeptides
Vikentia [17]
What  would  happen  if  M RNA   were  radio actively  labeled  instead  of  polypeptides  is   that    instead  of  one  seeing  the  DNA  passing  through  all  the  molecular  factories  you  will  instead see  just  messenger  RNA   taking  code  and   delivering  it  to  Ribosome.  This  is  mainly  found   in   cytoplasm  and  Endoplasmic  recticulums.

Alpa wants to change 0.54 kilometers into a smaller metric unit
wlad13 [49]

If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.

<h3>What is a Metric unit?</h3>

A Metric unit may be defined as a technique of measurement in which the basic units are the meter, the second, and the kilogram. These units are interchanged with one another by using several formulas of conversion.

The complete question is as follows:

Alpha wants to change 0.54 kilometers into a smaller metric unit. She will have to:

  • multiply
  • divide
  • add
  • subtract

Therefore, If Alpa wants to change 0.54 kilometers into a smaller metric unit, she will be required to multiply.

For example, In case, if she wants to convert 0.54 into meters, then she has to multiply it by 1000, that is, 0.54 * 1000 = 540 meters.
