the purpose for heat fixing is to kill the organism and fix the slide as fluid splatter can release bacteria as an aerosol so the fluid is completely evaporated before heat fixing. therefore option C i.e. bacteria may lyse in the fluid when heated.
Add Answer to:
It is important to gently evaporate off the fluid that the bacteria are in before heat...

5. Why are simple stains able to "stick” to bacteria? Explain the chemical properties of the stain and bacteria surface. 3-Preparation of Bacterial Smears and Simple Stains Introduction Microbial cultures are handled using aseptic technique. Aseptie technique is a set of procedures used to minimize contamination of materials by microorganisms from the environment, and to minimize the spread of cultures around the laboratory. In this experiment, you will be using an inoculating loop to transfer bacteria from a culture tube...

In Bacteria, translation of nascent RNA transcripts is often initiated before transcription is terminated. When this occurs: Select one: a. RNA is transcribed 3'=>5' and amino acids are added to the carboxy terminus of the growing polypeptide as the ribosome moves 5' => 3' along the mRNA b. RNA is transcribed 5'->3' and amino acids are added to the amino terminus of the growing polypeptide as the ribosome moves 3'=> 5' along the mRNA c. RNA is transcribed 3'=> 5'...

3) Insulating a Cold Fluid Line This is a steady-state problem, and latent heat eonsiderations do not matter As show in Fig. (a), an uninsulated hose of outer radius r1 cm is used to transfer a liquid refrigerant at a 273 K Tice r 1 cm uniform temperature T 265 K. Since the hose is uninsulated, the outer surface is also at 265 K. Because the outer surface of the hose is below the melting point of water, a layer...

Police Report: There were two individuals involved in the accident. No other passengers were present and no other vehicles were involved. There was a truck of mass 1,936 kg traveling Southbound on H and a compact car of mass 1,077 kg travelling Northbound on HWY 26. A bystander claims to have watched the vehicles collide and slide Southbound off the road into a tall grassy ditch. The grass was determined to have a coeficient of friction of 0.6, while the...
