Part A Yosef first looks at a prepared slide that includes several paramecia. He starts with a magnification of 40×, and then increases the magnification to 100× and 400×.

Describe how Yosef’s view of these cells and their parts changed as he transitioned through the microscope's three levels of magnification. Be sure to identify at least one cell structure or part of the paramecium in your description.

What are tissues? a groups of tissues that work together b basic units of structure and function c groups of cells that perform the same function d multiple organs that perform a major function

Vinegar has a ph of 3, and household ammonia has a ph of 11. is the concentration of h+ greatest in the vinegar or ammonia?

Use the drop-down menus to match each part of the scenario to the correct scientific practice. akira records the speed of a reaction without a catalyst and then with a catalyst. akira creates a reaction without a catalyst and repeats the reaction with a catalyst. akira turns in a written lab report to his science teacher. akira wonders, "will adding a catalyst speed up this chemical reaction? " akira writes in his notes that adding a catalyst sped up the chemical reaction because the catalyst lowers the activation energy needed to get the reaction started.
