Alyssa is observing two cells, X and Y. Each cell is from either a plant or an animal. She records some of her observations in a chart.
Cell Observations
Cell X
Cell Y
has lysosomes
lacks lysosomes
lacks a cell wall
has endoplasmic reticulum
has ribosomes
has a nucleus
Which additional observation will Alyssa most likely make?
Cell X has a cell membrane, and Cell Y does not.
Cell Y has a cell membrane, and Cell X does not.
Cell Y has a larger vacuole than Cell X.
Cell X has a larger vacuole than Cell Y.

Cell Y has a larger vacuole than cell X.

Explanation:

From the above observations I made out that cell X is animal cell and cell Y is a plant cell.

Cell Y has a larger vacuole than cell X.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
