. Recent studies in bone research indicate that using ultrasound on a broken bone can decrease the healing time by 25%. Which of these are the most basic levels of organization involved when a bone heals? Cells and tissue Cells and organ system Organ system and organism Tissue and organ system

Cells and tissue

Explanation:

Cells are the most basic unit of life made up of several organelles that perform various functions which enables the cell to exist.

An aggregation of cells is called a tissue. The bone is composed of several interconnected cells and tissues.

A bone heals when bone cells and tissues are gradually repaired. Hence, the most basic levels of organization involved when a bone heals are cells and tissues.
