Atoms are the most basic unit of matter. Two or more atoms from the same or different elements can combine to form molecules. Cells are the most basic unit of life. Cells are made up of many different types of molecules. Which of the following accurately shows higher levels of organization within organisms, from least complex to most complex?
A. cells → organs → organ systems → tissues → organism
B. cells → tissues → organs → organ systems → organism
C. cells → organ systems → organs → tissues → organism
D. cells → organs → tissues → organ systems → organism

B

Explanation:

Because cells make tissues which then combine to make organs which then further combine to form system

Which makes organisms like me and you

B

(An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids. For example, water is composed of hydrogen and oxygen atoms that have combined to form water molecules.)

Explanation : Because cells make tissues which then combine to make organs which then further combine to form system
