Plant cell shows distinguishing features from the animal cell which can be easily observed like:
1. Shape: Plant cell is usually rectangular while the animal cell is circular.
2. Membrane : Plant cell posses two layers- outer cell wall and inner plasma membrane while the animal cell only plasma membrane.
3. Vacuole: plant cell contains a single large vacuole whereas animal cell contains small vacuole if any.
4. Ribosomes: plant cell posses more free cytoplasmic ribosomes while animal cell contains more attached ribosomes.
On the basis of this, we can predict that James is preparing a plant cell with balloon shoeing large vacuole and marbles as ribosomes.
Thus, option B is the correct answer.
Answer:
B. a bowling ball
Explanation:
According to Newton's law of universal gravitation every body attracts another body by an amount of a force that is directly proportional to the product of the two bodies' masses and inversely proportional to the square of the distance between them. Knowing this then, it becomes clear that the body with the biggest mass will exert the greatest gravitational pull. From this list the ball with the biggest mass will be a bowling ball.
<span>This statement is false. When breaking down polymers into monomers, the reaction that takes place is hydrolysis.
Remember when combing monomers the water is taken out dehydration, when breaking them up, you have to add a cleaved water molecule, and the breaking of water is hydrolysis.</span>
