Question

the human body highlights some of the levels of biological organization. in terms of biological organization, place each statement in order from least to most complex. hint: look for key words in the item descriptions to help identify their placement of biological organization. start by choosing the first item in the sequence and clicking, dragging, or using your keyboard to select it. the brain is made up of four lobes and controls most body activities. red blood cells contain the protein hemoglobin, which transports oxygen throughout the body. the digestive system helps break down your food and the circulatory system transports the nutrients from your food to other parts of your body. carbon is a necessary element that is essential for all life. blood is made primarily of red blood cells, white blood cells, platelets, and plasma. together, blood serves many functions such as transporting oxygen and nutrients throughout the body. oxygen becomes a gas when two oxygen atoms are bonded together.

Explanation:

Levels of biological organization range from atoms to organisms. Elements (carbon), molecules (oxygen - gas), cells (red - blood cells), tissues (blood), organs (brain), and organ - systems (digestive and circulatory) are in increasing complexity.

Answer:

1. Carbon is a necessary element that is essential for all life.
2. Oxygen becomes a gas when two oxygen atoms are bonded together.
3. Red blood cells contain the protein hemoglobin, which transports oxygen throughout the body.
4. Blood is made primarily of red blood cells, white blood cells, platelets, and plasma. Together, blood serves many functions such as transporting oxygen and nutrients throughout the body.
5. The brain is made up of four lobes and controls most body activities.
6. The digestive system helps break down your food and the circulatory system transports the nutrients from your food to other parts of your body.
