Answer:
The correct choices are:
A. At random
D. Represent the population
Explanation:
- Random sampling ensures that every member of the population or group has an equal chance of representation.
- Random sampling eliminates the possibility of response or sample bias which gives a universal sample that uniformly represents all members of the population.
- A good sample should represent the entire population. This can be achieved by through random sampling.
- Convenience and volunteer based samples both have an increased risk of response bias. These samples will only represent selected individuals instead of the entire population.

Explanation:
Answer:
Kupffer cells, also known as stellate macrophages due to their particular structure while viewed under a microscope, were first identified by scientist Karl Wilhelm von Kupffer, after whom the cells were named, in 1876.
These cells, whose origin is in the yolk sack during fetal development, later on move to the liver where they will stay and further differentiate into their mature versions.
These cells are part of the liver cells, and are found particularly on the walls of the sinusoids, where they perform their two most important tasks. First, these cells are part of the immune system, as they are essentially macrophages. However, their role is pretty unique, as they are responsible not just for phagocytosis of invading bacteria, and other pathogens, and initiating immune responses, but also, this cell plays a role in decomposing red blood cells who are dying, and taking up the hemoglobin from them to further break that into reusable globin, and the heme group, from which iron is further extracted to be re-used and also to create bilirrubin, a part of bile.
Finally, these cells have been found to be connected to hepatic cirrhosis, as in their process of detoxifying ethanol, they produce toxins that force the liver cells to produce collagen, and thus to become fibrous.
