These are the rght ones lol. A1234 got 1 wrong, that is number 3. he said C, its actually A. Be Safe everyone!

real answer trust me

Agree with first post. Have no idea about the second.

3. is A!!!

To determine which of the options can be seen using a light microscope, we need to consider the resolving power of the microscope and the sizes of the objects in question.

a. A virus - Most viruses are incredibly small, often ranging from about 20 to 400 nanometers in diameter. The resolving power of a typical light microscope is around 200 to 250 nanometers, which means it cannot detect individual viruses. Therefore, a light microscope is not suitable for directly observing viruses.

b. A DNA molecule - DNA molecules are much smaller than viruses, with typical lengths in the range of a few nanometers. Due to their small size, DNA molecules cannot be visualized directly using a light microscope.

c. A human skin cell - Human skin cells are relatively large compared to viruses and DNA molecules, with sizes typically ranging from 30 to 50 micrometers in diameter. These dimensions fall within the resolving power of a light microscope, making it possible to observe human skin cells using this type of microscope. Therefore, a human skin cell could be seen using a light microscope.

d. A protein - Proteins are much smaller than cells, and their size can vary greatly depending on the specific protein. However, on average, proteins are much smaller than the resolving power of a light microscope. Therefore, individual proteins cannot be directly visualized using a light microscope.

In conclusion, based on the resolving power of a light microscope and the sizes of the given objects, the correct choice is c. a human skin cell.
