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 ____ each other. skeletal muscle tissue contains ____ to move the body.
options: close to, contract, and relax, far apart from

Explanation:

1. The text explains tissues are groups of similar specialized cells organized together, so "close to" fits the first blank as the cells are grouped.
2. The example notes skeletal muscle cells contract together to shorten the muscle and move the arm, so "contract and relax" describes the action these cells perform for body movement.

Answer:

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