Energy convention: Convection is the motion of a fluid driven by temperature differences across that fluid. When a fluid is heated, the region in closest contact with the heat source becomes less dense due to increased kinetic energy in the particles. Convection is one of the fundamental ways that heat is transferred
Answer:
the correct answer is option ( B )
Answer:
c. because arteries carry high pressure blood from the heart
Explanation:
Arteries carry the oxygenated blood that is pumped directly from the left ventricle of the heart. Since they receive blood from the heart, the blood pressure is higher in arteries than veins. To withstand the higher pressure of blood pumped by heart, arteries have thicker walls than the walls of veins.
The best answer is D.
A carbon sink is anything that absorbs more carbon than it produces or releases.
The main carbon sinks found in nature are plants, the ocean and soil. Plants such as trees capture carbon dioxide from the atmosphere and use it in photosynthesis. Part of this carbon is transferred to soil as the trees and other plants die and decompose.
Due to the effectiveness of trees and other plants as carbon sinks, the Kyoto protocol proposed that emission reduction can be achieved through absorption of carbon dioxide by these plants.
