How does carbon cycle through Earth's systems? A. Photosynthesis releases carbon dioxide into the atmosphere.
Cellular respiration uses carbon dioxide.

B. As fossil fuels are burned, carbon dioxide is made available for
photosynthesis in animal cells. When the animals die, carbon is
released into the soil, and the animal remains form new fossil
fuels

C. Animals absorb carbon dioxide through their skin. Dead animals
release carbon into the soil. Plants absorb the carbon from the
soil and release carbon dioxide during photosynthesis.

D. Plants absorb carbon dioxide through their leaves. Animals take in
the carbon when they eat the plants. Animals exhale carbon
dioxide. Dead plants and animals release carbon into the soil.

Plzzz hurry im being timed ! humans, like other organisms, require energy for growth and repair. when cells create atp for energy, carbon dioxide is produced as a waste product. how does the body respond to this process in order to maintain homeostasis? a. the digestive and respiratory systems interact to move carbon dioxide to the lower intestine, where it is transformed into methane. b. the circulatory and digestive systems interact to move carbon dioxide to the stomach, where it to break down food. c. the nervous and urinary systems interact to move carbon dioxide to the kidneys, where it is absorbed into the bloodstream. d. the circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.

Which of the following statements is true? a. there are more chromosomes in an organism than there are genes. b. there are more genes in an organism that there are chemical bases. c. dna is made of sugar, phosphate, and carbon. d. genes are found in specific locations on a chromosome.

Which is an advantage of having memory cells when a pathogen is encountered for a second time. a) the memory cells are what proliferate into clones of cells in response to the binding of an antigen. b) memory cells are vital to the primary immune response in that they immediately recognize pathogens even at the first encounter. c) memory cells are essentially effector cells that are short lived and attack antigens even without having a receptor specific to that antigen. d) it ensures that more lymphocytes with a receptor specific to a particular antigen will be present than in a host that had never encountered that pathogen.
