Convection- is the heat transfer due to the bulk movement of molecules within fluids such as gases and liquids, including molten rock. Convection includes sub-mechanisms of advection, and diffusion.
Explanation:
Cities become warmer than their rural surroundings due to buildings, roads and other infrastructure replacing open land and vegetation. “Surfaces that were once permeable and moist,” writes the“become impermeable and dry.”
During the daylight hours, temperatures inside large cities range between 1.8 and 5.4 degrees F warmer than their surrounding areas. At night, city temperatures can be as much as 22 degrees F warmer.
This phenomenon was believed to be the result of concrete and other structures absorbing heat throughout the day and then gradually releasing it at night. But a new study published last week in the journal Nature offers a different explanation: Convection.
How air moves through a city during the day has a greater role in trapping heat, the study claims, than the disappearance of vegetation and the existence of urban structures.
The answer would be "<span>Cyclins are proteins that regulate when and how often a cell divides". Cyclins belong to a family of proteins that control the progression of a cell through its respective cell cycle. This is initiated by activating cyclin-dependent kinase (CDK) enzymes which regulate </span>transcription of RNA and process mRNA during mitosis.
Industrialization is the process by which an economy is transformed from a primarily agricultural one to one based on the manufacturing of goods. Individual manual labor is often replaced by mechanized mass production, and craftsmen are replaced by assembly lines.
Answer:
In both cases, the person is deprived of ATP source as the aerobic cellular respiration comes to halt.
Explanation:
At higher altitudes, low oxygen pressure deprives the cells of oxygen to serves as the terminal electron acceptor. In the absence of molecular oxygen, electron transport from NADH and FADH2 to O2 can not generate the proton concentration gradient required for ATP synthesis.
Cyanide poisoning also stops ATP synthesis by inhibiting the electron transfer from cytochrome oxidase to oxygen. Cellular respiration is a source of ATP for living aerobic cells. In the absence of ATP synthesis, the person is deprived of energy sources and feels weakness, dizziness, confusion, and shortness of breath.
