How do plant cells make sugars from sunlight and then convert the sugars to cell energy/atp
the first process is called sea-floor spreading (rifting when it happens on land) and the second process is called subduction. both processes are part of plate tectonics.
answer : there are 5 layers of atmosphere surrounding the earth
the last layer of atmosphere surrounding earth is troposphere it has 17 km thickness in equatorial zone and 7 km in the poles
it is the first atmospheric layer closest to earth's surface.
it is the region where weather occurs.
the temperature of the troposphere decreases with an increase in height.
lactic acid fermentation ocurrs in muscle cells when oxygen is in low supply
the lactic acid fermentation in the muscles cell occurs when muscles work faster and it occurs due to the lack of supply of oxygen in the cell. the lactic acid fermentation is a type of aerobic respiration. the lactic acid formation is due to excessive exercise by individuals and oxygen which is essential for living, is less in the muscle which causes the feeling of burning in the muscles.
scientists are constantly finding out about new elements and update the elements when they find new ones.
