Answer:
Plant biomass will increase as a result of photosynthesis. During photosynthesis, plants produce glucose and oxygen from carbon dioxide and water, using light energy from the Sun. ... Photosynthesis is an endothermic reaction as it requires light energy to react carbon dioxide and water to produce glucose and oxygen.
 
        
             
        
        
        
Answer:2 the lupine dependent butterflies would disappear.
If the spraying of pesticides will remove all the insects then there will be no insect that will pollinate the lupine flowers. So this will cause removal of lupine species from the environment. And the lupine dependent butterflies will not be able to release their egg on these specific flower and will also disappear from the environment. 
The removal of lupine flower from the environment will lead disappearing of these lupine dependent butterflies. 
 
        
                    
             
        
        
        
I believe that the loop of Henle is the hairpin structure that connects the proximal and distal convoluted tubules. The loop of Henle is composed of the ascending and the descending limb. The descending loop of Henle connects the proximal convoluted tube with the ascending limb of the loop of Henle, while the ascending loop of Henle connects the descending limb of the loop of Henle with the distal convoluted tubule. 
        
             
        
        
        
Answer:
The Z lines and H- zone shortens during the muscle contraction.
Explanation:
Sarcomere is the area between the two Z lines. The Z- lines are present in the centre of I - band and H - zone is present in the A - band. The actin filaments which are thin filaments present in I- band and contracts, slide over the myosin filament during contraction. 
The I - band, H- zones are became shortens as they are thin than the A- band. It is anisotropic band having thick myosin filaments. They are not flexible and remain in its constant shape during the muscle contraction.
After the muscle contraction, the A- band and the H- zone comes to their original shape. In other words, the sarcomere shortens and comes back during muscle contraction, and relaxation.
