<h2>Answer:</h2>
The boiling of water in the iron pan is the activity in which both conduction and convention are used.
<h3>Explanation:</h3>
Energy is transferred from one part of the matter to other part in three ways:
- Conduction
- Convection.
- Radiation.
Conduction is the movement of heat from the collision of the microscopic particles in the matter.
While convection is the transfer from the movement of fluids from one place to another.
In the water boiling activity, the pan is heated by the flame from taking the energy in the collision of atoms in the pan and the energy is transferred into the whole pan and eater molecules. This is conduction while in pan water movement from the bottom to top of pan is by convection.
Thick or dense smears less likely to provide a good smear preparation for microscopic because it will diminish the amount of light that can pass through making it difficult to visualize the morphology of single cells under the microscope. Some times the stain can't penetrate all of the bacteria.
<h3 /><h3>What is a microscopic smear?</h3>
- A smear is a microscopic specimen.
- A swab or loop, or the edge of another slide, is used to spread the sample to be examined, such as blood or microbial culture, thinly and unevenly across the slide.
- Smear preparation involves spreading a small amount of sample on a slide and air drying the film before staining and microscopy.
- The conventional method, blood film method, drop and rest method, and water-wash method are the four types of smearing methods.
- Smear microscopy entails collecting a biological sample (typically sputum or other clinical material), fixing it thinly on a glass slide, and staining it with a dye that binds specifically to mycobacteria (making them easier to identify under a microscope).
