Question

1. the liver produces bile, which helps to break down fats and carry away wastes. the liver also filters toxins from the blood. what three things must be true if the liver is an organ? a. it is composed of different tissues. b. it has a specific function in the body. c. it is part of at least one organ system. d. it is found in every type of multicellular organism. e. it is a group of similar cells that carry out the same function. 2. sep use evidence based on the livers functions, which system or systems does the liver belong to? 3. systems and system models draw a model to show how the body is a system of subsystems made up of cells. explain the subsystems.

Explanation:

1. An organ is composed of different tissues, has a specific function in the body, and is part of at least one organ - system. Option d is incorrect as not all multicellular organisms have a liver. Option e describes a tissue, not an organ.
2. The liver is involved in digestion (producing bile to break - down fats) and detoxification (filtering toxins from the blood), so it belongs to the digestive system and the excretory system.
3. A model of the body as a system of subsystems made up of cells could show the hierarchical organization. For example, cells make up tissues, tissues make up organs, organs make up organ - systems, and organ - systems make up the body. The muscular system helps with movement, the respiratory system helps with gas exchange, etc.

Answer:

1. a. It is composed of different tissues.

b. It has a specific function in the body.
c. It is part of at least one organ system.

1. The liver belongs to the digestive system and the excretory system.
2. A model can show cells forming tissues, tissues forming organs, organs forming organ - systems, and organ - systems forming the body. For example, the muscular system helps with movement, the respiratory system with gas exchange.
