Answer:
During light reaction of Photosynthesis ATP and NADPH are formed.
Explanation:
Reactions driven by solar energy
H2O=H+ + OH-
4OH- - 4e- =4OH
4OH=2H2O+O2
Second reaction
NADH+e- +H+=NADPH
Carbon dioxide fixation occurs during Calvin cycle.Carbon dioxide is being fixed into glucose molecule.
The name of the enzyme is Ribulosebisphosphate Carboxylase(RUBISCO)
The normal substrate for this enzyme is Ribulose bisphosphate(RUBP)
A large glucose molecule requires facilitated diffusion but an oxygen molecule <span>does not is a semipermeable membrane.</span>
Answer:
Gravitational force
Explanation:
Gravitational force is the force that attracts an object down to the earth. It’s also the reason why we don’t float on this planet. This force is also why anything that isn’t thrown up must come down.
In space and other planets with little or no gravitational force ,organisms float over there which makes its inhabitation by organisms very difficult.
The DNA is splitting in two, thymine pairs with adenine, and guanine pairs with cytosine
Answer:
B. The tropospheric gases move becuase of convection currents.
Explanation:
The uneven heating of the regions of the troposphere by the sun ( the sun warms the air at the equator more than the air at the poles )causes convection currents, large-scale patterns of winds that move heat and moisture around the globe. In the Northern and Southern hemispheres, air rises along the equator and subpolar ( latitude about 50 to about 70 north and south ) climatic regions and sinks in the polar and subtropical regions. Air is deflected by the Earth's rotation as it moves between the poles and equator, creating belts of surface winds moving from east to west ( easterly winds ) in tropical and polar regions, the winds moving from west to east ( westerly winds ) in the middle latitudes. This global circulation is disrupted by the circular wind patterns of migrating high and low air pressure areas, plus locally abrupt changes in wind speed and direction known as turbulence.
