Question

cells are tiny—even the largest cells in the human body are smaller than the thickness of your fingernail! alone, a single cell cannot do much. but when many similar specialized cells are organized together, they form a system called a tissue. the cells work together to allow the tissue to perform its function. this picture shows skeletal muscle tissue in the human bicep. it is made of many skeletal muscle cells. a single skeletal muscle cell cannot produce significant movement. but when all of the skeletal muscle cells in the bicep muscle tissue contract together, they can shorten the muscle and move the arm. complete the paragraph. a tissue is composed of types of cells that are each other. skeletal muscle tissue contains that can contract and relax to move the body.

Explanation:

The text states that a tissue is formed by many similar specialized cells. So, for the first blank, it's "similar" as the cells are of the same kind. For the second blank, since they work together, "organized with" makes sense. And skeletal muscle tissue has "skeletal muscle cells" which contract and relax. The last blank is "together" as the cells act collectively.

Answer:

A tissue is composed of similar types of cells that are organized with each other. Skeletal muscle tissue contains skeletal muscle cells that can contract and relax together to move the body.
