The option that would be best for making Julia model look more like a plant cell is putting the bag inside a larger clear plastic bag.
<h3>What is a cell?</h3>
A cell is the basic and functional unit of life. Every living organism is made up of one or more cells.
However, a plant cell is morphologically different from an animal cell. One of the major differences is that a plant cell posseses a cell wall that protects the cell.
According to this question, Julia made a model of a cell in a clear plastic zipper bag. She used a marble for the nucleus and pinto beans for mitochondria.
Therefore, the option that would be best for making Julia model look more like a plant cell is putting the bag inside a larger clear plastic bag which will represent the cell wall.

So, the answer would be 20 cm
Answer:
Calcium would displace barium.
Explanation:
Ba(NO₃)₂ + Ca --> Ca(NO₃)₂ + Ba
There are two types of compounds: molecular/covalent and ionic.
Molecular/covalent compounds are non-metal + non-metal.
Ionic compounds are metal + non-metal.
Looking at the periodic table, barium is a metal. Calcium is also a metal.
Checking a polyatomic ions chart would tell you NO₃⁻ is a non-metal because it has a negative charge.
Since there is no metal + metal compound, the calcium metal would displace barium. The compound remains ionic.
<span>An atom is composed of at least three types of subatomic particles. An electron has properties of both waves and particles. An atom is mostly empty space with a dense, positively charged nucleus.</span>
Extreme weather e.g. snow and cold weather. Another main contributing factor is that many places have a long dry season.
