What are bio-fuels considered carbon neutral?
uranmaximum [27]
“The U.S. government considers biodiesel to be carbon-neutral because the plants that are the sources of the feedstocks for making biodiesel, such as soybeans and palm oil trees, absorb carbon dioxide (CO2) as they grow. The absorption of CO2 by these plants offsets the CO2 that forms while making and burning biodiesel.”

How do the circulatory and respiratory system interact to provide muscle cells with oxygen during a long distance race?
Orlov [11]

Answer:

Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.

The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.

The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.

The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.
