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 defines tissue as a group of similar specialized cells working together. For skeletal muscle tissue, it is made of skeletal muscle cells that contract/relax to move the body. We fill in the blanks based on this context:

1. Tissues are made of one (similar) type of specialized cells, so first blank is "one".
2. These cells are similar to each other, matching the definition of tissue from the opening text, so second blank is "similar to".
3. Skeletal muscle tissue contains skeletal muscle cells, so third blank is "skeletal muscle cells".
4. These cells act together to move the body, so fourth blank is "together".

Answer:

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