Question

While packing equipment for a field study, Dr. Mokembe was trying to determine if he needed to include both a dissecting and a compound microscope. In which case would a scientist choose to use a dissecting microscope rather than a compound microscope?Oncologists are doctors which specialize in diagnosing and treating cancer. Certain cancers have markers on the surface of affected cells.

Answer 1

A scientist would choose to use a dissecting microscope when examining larger objects or specimens, such as tissues.

Step-by-step explanation:

When deciding whether to use a dissecting microscope or a compound microscope for a field study, a scientist would choose to use a dissecting microscope when examining larger objects or specimens, such as tissues.

Dissecting microscopes have a lower magnification than compound microscopes and are designed to provide a three-dimensional view of the specimen, making it easier to manipulate by hand. They are often used to study the structure and anatomy of whole organisms.

Answer 2

A scientist would opt for a dissecting microscope over a compound microscope when examining larger specimens, needing a three-dimensional view, or when performing manual manipulations, due to the dissecting microscope's lower magnification, corrected image orientation, and depth perception.

Step-by-step explanation:

A scientist would choose to use a dissecting microscope rather than a compound microscope when they need to look at larger specimens that require a three-dimensional view. Dissecting microscopes offer a lower magnification ranging from 20 to 80 times the object size, which is suitable for examining whole organisms, tissue structures, or any other sizable specimens. Unlike compound microscopes, dissecting microscopes allow for the observation of thick objects with multiple components in focus at the same time. Moreover, dissecting microscopes have optics that correct the image to appear right-side up and not inverted, benefitting scientists who perform manual manipulations on the specimen. Lastly, the binocular design offers a depth perception enabling easier dissection or manipulation of the specimen.
