Answer:

Option 1, cell wall

Explanation:

A cell wall is both tough and flexible at the same time in order to protect the cell wall from various losses. It also regulates the transmission of material in and out of the cell through a semipermeable membrane.

A cell wall in plant shape is made up of cellulose, hemi-cellulose and pectin which provide strength and rigidity to the cell.

Compare and contrast optical and radio telescope
Umnica [9.8K]

Hallo~~~

When comparing optical and radio telescopes, we know that both of these telescopes detect a certain band of the electromagnetic spectrum.

When contrasting optical and radio telescopes, we know that optical telescopes have higher equipment (polished mirrors, accuracy), and that they depend on weather. Radio telescopes have lower equipment (less precise reflectors), and depend on diff. things such as thermal radiation and man-made emissions.
