Answer:
Explanation:
Jupiter's fifth moon, Io, is the most volcanically active body in the solar system. Plumes of sulfur spew upward as high as 190 miles. The surface of Io is splotched with lava lakes and floodplains of liquid rock.
Astronomers have mapped about 150 volcanoes on the moon, some of which blast lava 250 miles (400 km) out into space. There are volcanoes all over Io's surface, and as scientists perform observations they still occasionally see new hotspots pop up. For example, NASA's Juno spacecraft, which is currently orbiting Jupiter, found a possible new hotspot on Io on Dec. 16, 2017.(k r
If a p53 gene is defective it may cause cell cycle to stop functioning normally. Without this cell cycle check, cells will divide continuosly creating many chromosomal damage.
Answer and Explanation:
Most enzymes are proteins in nature hence they are sensitive to changes in the pH. Enzymes may be denatured by extreme levels of hydrogen ions. Any change in pH, even a small one, alters the degree of ionization of an enzyme’s acidic and basic side groups and the substrate components as well. Ionizable side groups located in the active site must have a certain charge for the enzyme to bind its substrate. Neutralization of even one of these charges alters an enzyme’s catalytic activity. Excessive acidity or alkalinity renders them inactive.
