The answer to the question above is letter a. melting.
>Exothermic is the giving off heat energy the  transfer of energy to the surroundings.
>In exothermic reaction, the energy is
usually transferred as heat energy
<span>> Other example of exothermic is combustion</span>

Ans. 
Diffusion, osmosis, and active transport are mechanism of cellular transport that involves movement of molecules through plasma membrane. Diffusion shows movement of small, hydrophobic particles without the help of protein molecules through cell membrane along the concentration gradient. 
Osmosis involves movement of water molecules against concentration gradient (from an area of high solvent concentration to an area of low solvent concentration) through cell membrane. 
Active transport shows movement of particles, against the concentration gradient, means from a region of higher to lower concentration of molecules through cell membrane. It involves transport through membrane proteins. 
Thus, the part of cell, which is affected by the movement of molecules through osmosis, diffusion, and active transport is cell membrane or plasma membrane. 
 
        
             
        
        
        
Research major earthquakes on google, or another website. I would go with question 1, Where is your earthquake? I would do the Haiti earthquake where the earthquake is in Haiti. Do more research on Google, because I cannot provide you with a link to an article because Brainly will not allow me to do so. Just research "major earthquakes" in Google and you will be good to go. Hope this helped!
