The answer would be A. Methane
The three methods of carbon dioxide transport in the blood are dissolution in blood plasma, binding to hemoglobin, and carried in the form of bicarbonate. About 7% of the carbon dioxide is dissolved in the blood plasma. The majority of the remaining 93% is carried as part of the bicarbonate buffer system while the rest binds to hemoglobin.
The correct answer is iron.
The scientists from Britain discovered a soap with magnetic characteristics that could exhibit huge applications in the manner to fight against the damaging oil spills. In the mentioned soaps, the iron-abundant salts are supplemented to establish metallic centers inside the particles of the soap.
After the solution is treated in a water source, a magnet was utilized to subjugate both the surface tension and gravity of the water, levitating the iron-rich scrubbing bubbles so that they can be withdrawn easily.
Answer:
To maintain homeostasis
Explanation:
Effectors are organs, cells or tissues that provides the required output after receiving a feedback from the control center. Nerve impulse instructs the effector to bring things into balance and required range. They then influence the magnitude of stimulus and maintain homeostasis.
