On the earth surface
Explanation:
The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted. 
- The sun releases radiation in form of short-wave. 
- They are usually more energetic and with short wavelength and a high frequency. 
- When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat. 
- Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body. 
- When these radiations enters the earth, they are re-radiated back as long waves with lower energy. 
- Earth is cooler than the sun
- When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back. 
- When the short waves are absorbed, they lose some of their their energy to the earth surface. 
- The remainder is radiated back as less energetic long waves. 
- The hotter a body is, the more energetic the radiation it releases.

Answer:
B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose.
Explanation:
The following statements that support the conclusion that photosynthesis follows the law of conservation would be B.) The total mass of B and C, which are water and carbon dioxide, is equal to the total mass of A and D, which are oxygen and glucose. We can conclude this because the law of conservation states that for any transfer of mass, it will always stay the same, meaning that you cannot add to it nor remove from it. Option A would not be correct because the question asked about photosynthesis, and A is describing cellular respiration. Options C and D would also not be correct because when you add up the values in the way that they are listed, it does not sum up to the statement. Here are all of the letter combinations added together, based on the letter choices:
B and C ➡ 372
A and D ➡ 372
A and B ➡ 300
C and D ➡ 444
A and C ➡ 456
B and D ➡ 288
Notice how the first two listed add up to 372. And because this matches option B, that will be your answer.

Answer:
b) In allosteric regulation, a small molecule binds to a large protein and causes it to change its shape and activity.
Explanation:
Allosteric regulation refers to the activity control of an enzyme by binding small molecules to regulatory sites on It. This binding causes an alteration of the protein conformation and consequently the shape of the active site and its catalytic activity are altered. Regulatory enzymes can act by either stimulating or inhibiting the activity of a protein.
 
        
             
        
        
        
Skeletal system.
Without a proper skeleton, we would not have enough rigidity to properly move. We'd be an awkward pile of skin, muscle & bodily fluids. 
Hope that helps!
