13.A dividing cell has a line of vesicles on the metaphase plate between the two daughter nuclei. Is it a bacterium, plant, or animal cell

plant cell

Explanation:

The Golgi apparatus is a cell organelle responsible for modifying, sorting and packaging proteins and lipid molecules into vesicles (i.e., Golgi vesicles) for their delivery to targeted cell sites. A plant cell can contain many -even hundreds- of Golgi apparatus. During cell division of plant cells, Golgi vesicles combine at the metaphase plate in order to form a structure called phragmoplast. Subsequently, the cell plate formed by phragmoplast vesicles grows from the center to the cell walls. Finally, the vesicle membranes fuse to form a plasma membrane that divides the plant cell into two cells.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
