Answer:
C
Explanation:
First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
 
        
             
        
        
        
The environmental parameters that should be monitored to ensure that the plant is not adversely affecting the animal species near the plant are MIGRATING BIRD POPULATION AND THE CARRY CAPACITIES OF THE LOCAL ANIMAL SPECIES. Monitoring these parameters, we allows the city to know if the plant set up is affecting the population of the animals in the area.
