Question

1. categorize the following and order the categories from smallest to largest: archaean cell, bacterial cell, carbon, carbohydrate, cheek cell, chloroplast, covid - 19, hydrogen, electron, neutron, lipid, nucleic acid, nucleus, onion bulb cell, protein, proton
2. what are proteins and their uses in cells? of the cell structures we have learned about, which ones include proteins as part of their structure or function?

Explanation:

1. Atoms are the smallest units. Sub - atomic particles like hydrogen, electron, neutron, proton are even smaller. Molecules such as lipid, nucleic acid are composed of atoms. Organelles like chloroplast are part of cells. Cells include archaean cell, bacterial cell, cheek cell, onion bulb cell. Viruses like COVID - 19 are acellular but are smaller than cells. Proteins are macromolecules. So, the order from smallest to largest is: electron, hydrogen, neutron, proton, lipid, nucleic acid, protein, chloroplast, COVID - 19, archaean cell, bacterial cell, cheek cell, onion bulb cell.
2. Proteins are part of cell membranes (structural), enzymes (catalytic function for biochemical reactions), and transport proteins (help in moving substances across the cell membrane).

Answer:

1. Electron, Hydrogen, Neutron, Proton, Lipid, Nucleic acid, Protein, Chloroplast, COVID - 19, Archaean cell, Bacterial cell, Cheek cell, Onion bulb cell
2. Proteins are part of cell membranes (structural), enzymes (catalytic), and transport proteins (for substance movement)
