Answer:
When a jogger starts to run, the rate at which his muscles produce CO2 rises sharply. The CO2 in his blood rises only slightly before he starts to breathe faster and his heart starts beating stronger. Soon his increased rate of CO2 production is balanced by an increased rate of CO2 removal. This would be an example of negative feedback because the jogger's circulatory and respiratory systems are systems regulator.
Explanation:
When an organism increases its partial pressure of carbon dioxide in the blood, it generates a decrease in the physiological blood pH that triggers the activation of a large number of enzymes and, as a gas, it increases its internal partial pressure in the body and thanks to this it spreads to the outside (environment by means of the lung exchanging it for oxygen) thanks to the fact that all gases ALWAYS diffuse to areas of higher partial pressure towards areas of lower partial pressure. That is why homeostasis, and gas exchange, occurs.
Answer:
neurons differ from other cells in the body because:
- Neurons have specialize cell parts called dendrites and axons. Dendrites bring electrical signals to the cell body and axons take information away from the cell body.
- Neurons communicate with each other through an electrochemical process.
- Neurons contain some specialized structures (for example, synapses) and chemicals (for example, neurotransmitters).

Answer:
Mitsumata
Explanation:
Mitsumata has been used since ancient times as a raw material for Japanese paper called “washi.” The tradition of using mitsumata as the raw material for making banknote paper has been passed down since it was first used for this purpose in 1879 (Meiji 12).
