Question

1. why are microscopes so important to scientists curious about cells? choose the two best answer.

d. because cells are too small to see with the naked eye.
c. because microscopes make large objects smaller.
a. because microscopes help light up small objects so we can see them.
b. because microscopes magnify large objects.

Explanation:

Cells are extremely small. Microscopes have the function of magnification. They can enlarge small objects (like cells) so that scientists can observe them. Option D correctly states that cells are too small for the naked eye to see. Option A is incorrect as microscopes' main function is magnification, not just lighting up (though lighting is sometimes a feature but not the key reason here). Option C is wrong as microscopes magnify (make small objects look larger), not make large objects smaller. Option B is incorrect as microscopes are for magnifying small objects (like cells), not large objects.

Answer:

D. Because cells are too small to see with the naked eye.
