To study the details of protein molecules on the surface of a cell, a biologist would likely use a (2 points) select one: a. scanning electron microscope b. transmission electron microscope c. compound light microscope d. dissecting microscope

scanning electron microscope

Explanation:

The scanning electron microscope has a very high resolution. In studying a protein on a cell surface, SEM offers a very plausible option since it gives a more magnified and better resolved image than the compound microscope.

SEM is now widely used in biological investigation that has to do with viruses and bacteria in order to obtain more accurate information about their cell structure.

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
