Metastatic melanoma ( if i’m not wrong )
cancer that begins in the skin cells, which spreads to other parts of the body ( in this case liver and brain)
Answer:
NAD+ act both as coenzyme as well as electron acceptor compound and get reduced to NADH by accepting electron.
Explanation:
NAD+ act as co enzyme of various biological catalyst such as malate dehydrogenase, isocitrate dehydrogenase etc.
NAD+ can act as co enzyme only in its oxidized form but not in its reduced form called NADH.
Many reaction needs NAD+ to occur such as conversion of glyceraldehyde 3 phosphate to 1,3 bisphosphoglycerate, malate to oxaloacetate.
That"s why NAD+/NADH ratio is kept very high because if this ratio bychance get low then it will hamper the normal redox potential of NAD+/NADH.As a result many biochemical reaction will not take place.
Answer:
Hurricanes are large, swirling storms. They produce winds of 119 kilometers per hour (74 mph) or higher. That's faster than a cheetah, the fastest animal on land. Winds from a hurricane can damage buildings and trees.
tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.
Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.
A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.
Wildfires are fires that burn out of control in a natural area, like a forest, grassland, or prairie. They often begin unnoticed. They spread quickly, and can damage natural resources, destroy homes, and threaten the safety of the public and firefighters. Humans cause most wildfires.

a volcano is a mountain or hill, typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
There are three main types of volcano - composite or strato,shield and dome. Composite volcanoes, sometimes known as strato volcanoes, are steep sided cones formed from layers of ash and [lava] flows. The eruptions from these volcanoes may be a pyroclastic flow rather than a flow of lava.
