Which structures protect the cell? check all that apply.

1. cell wall
2. cell membrane
3. mitochondrion
4. nucleus
5. ribosome
6. golgi body

Option 1, cell wall

Explanation:

Cell wall is an outer covering of the cell that is responsible for giving  shape and support to the cell. 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.

hence, option 1 is correct

i would have to say autosomal

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
