Answer: It is convenient to divide the photosynthetic process in plants into four stages, each occurring in a defined area of the chloroplast: (1) absorption of light, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) generation of ATP, and (4) conversion of CO2 into carbohydrates (carbon fixation). All four stages of photosynthesis are tightly coupled and controlled so as to produce the amount of carbohydrate required by the plant. All the reactions in stages 1 – 3 are catalyzed by proteins in the thylakoid membrane. The enzymes that incorporate CO2 into chemical intermediates and then convert it to starch are soluble constituents of the chloroplast stroma (see Figure 16-34). The enzymes that form sucrose from three-carbon intermediates are in the cytosol.
1/8=(1/2)^3 and the half life of radon is 3.8days
Half life is the time it takes for half of any amount of a radioactive substance to decay into something else.
Therefore for a sample of radon to decay to 1/8 of its original amount, it would take 3 x 3.8days=11.4 days
Answer:
Random motion in all directions.
Explanation:
It must be understood that the movement of atoms in a molecule is strictly based on the kinetic energy possessed by these particles.
Now, the gaseous state gives the highest level of freedom to these particles and thus they possess their highest kinetic energy in this state.
In gaseous helium, the atoms are expected to have a very high kinetic energy and thus they move in a haphazard or in an irregular manner.
This is principally due to the fact that in the gaseous state, atoms are most less confined and thus they are not restricted to a certain space.
This is in sharp contrast to the movement of atoms in the solid and liquid state. While atoms are mostly confined in the solid state such that they only merely vibrate about a fixed point, their movement in the liquid state is less restricted and they exhibit more freedom. This however is far less than the amount of freedom the gaseous state would avail its own particles.
