Question

the smallest unit of life that demonstrates all the properties of life is a(n) cell organism molecule question 13 protein synthesis takes place where? select all that apply. rough er ribosome mitochondria

Explanation:

1. For the first question, cells are the basic structural and functional units of life and can perform all life - processes like metabolism, growth, and reproduction. Organisms are made up of cells, and molecules are non - living components that make up cells.
2. For the second question, ribosomes are the sites of protein synthesis. The rough endoplasmic reticulum (Rough ER) has ribosomes attached to its surface and also participates in protein synthesis. Mitochondria are the power - houses of the cell and are mainly involved in energy production (cellular respiration), not protein synthesis.

Answer:

1. Cell
2. Rough ER, Ribosome
