atp.
carbon dioxide.
water.
which term refers to cells having different jobs in an organism?
multicellular
cell specialization
levels of organization
unicellular
which of these is a product of cellular respiration?
oxygen
water

Explanation:

First Question (Cellular respiration releases energy by breaking down)

Cellular respiration is the process where cells break down food molecules (like glucose) to release energy. ATP is the energy - carrying molecule produced, not broken down. Carbon dioxide and water are products of cellular respiration, not the substances broken down for energy.

• Multicellular means an organism has many cells, not about cell jobs.
• Cell specialization is when cells develop different structures and functions (different jobs) in a multicellular organism.
• Levels of organization refer to the hierarchy of biological structures (cell, tissue, organ, etc.), not cell jobs.
• Unicellular means an organism has one cell, so no different cell jobs.

Cellular respiration uses glucose and oxygen and produces carbon dioxide, water, and ATP. Oxygen is a reactant (used in respiration), while water is a product.

Answer:

A. food molecules.
