If a toxic chemical destroys the ribosomes, which cellular activity would be affected
first?

Protein production will be affected if a toxic chemical destroys the ribosomes.

Explanation:

Ribosomes are a cell structure that makes protein. Protein is one of the most important Biomolecules which is required by the cell to carry out cellular process.

Ribosomes can be discovered gliding inside the cytoplasm or embedded to the endoplasmic reticulum.  The area of the ribosomes in cell figures out what sort of protein it makes.

The protein synthesized by the free floating ribosomes are used by the cell for inter cellular functions, whereas the protein synthesized by the ribosomes embedded on endoplasmic reticulum is used for both inner as well as outer functioning of the cells.  

the answer is b. 0; 4

when the displaced particles are perpendicular to the direction the wave travels, is called a transverse wave, whereas in longitudinal wave the displace practices are parallel to the direction of the wave.

in the given image:

first image shows - longitudinal wave

second image shows - transverse wave

third image shows - longitudinal wave

fourth image shows - longitudinal wave
