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.

Vacuum filtration is more efficient and faster than filtration by the gravity method. But the set up of the vacuum filtration must be precise. Vacuum filtration is done under very reduced pressure hence there should be no gaps around the edges of the filter paper.
For a vacuum to be effective there must be no hole or gap in the equipment. Under vacuum conditions air is removed and the pressure is lowered. If there is gap then air would be continuously supplied and it would be difficult to remove air completely.
Electrical energy !! i hope this helped :))
Answer:
The strongest gravitational attraction between the two objects will be experienced when the distance between the two objects is smallest.
Explanation:
According to Newton's law of universal gravitation, the force of attraction between two objects is proportional to the products of their masses and inversely proportional to the square of the distance of separation between the two objects. This attraction between objects is known as gravity and it applies to all objects in the universe.
From the law of universal gravitation, since their is an inverse square relationship between gravitational force and the distance of separation between two interacting objects, an increase in the distance of separation will result in weaker gravitational forces. For example, if the distance of separation between two objects is increased by a factor of 2, then the force of gravitational attraction is decreased by a factor of 4 (since 2² = 4). However, if the distance of separation between the two objects is decreased by a factor of two, i.e. is halved, then the force of gravitational attraction is increased by a factor of 4.
Thus, the strongest gravitational attraction between the two objects will be experienced when the distance between the two objects is smallest.
