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 similar types of cells that are close to each other. skeletal muscle tissue contains many skeletal muscle cells that can contract and relax ______ to move the body.
options: together, independently

Explanation:

The text explains that tissues are made of specialized similar cells working as a group. Skeletal muscle tissue requires its cells to contract together to create movement, as a single cell cannot produce significant movement on its own.

Answer:

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