Budding  is  the  predominant  mode  of   asexual  reproduction  in  sponge. Budding  is  a  asexual reproduction  in  which  a  new  organism   develop  from  outgrowth or   from  bud   due  to  cell  division   at   one  particular  site. A  small  rounded  outgrowth  on  asexually  reproducing  organism  is  cabable  of  developing  into  new individual
        
             
        
        
        
Answer:
Option 2
Explanation:
I did not see the video referenced, but an invasive species is not always brought by people. Furthermore generally there are no limiting factors because it has no natural predators in the environment and often uses up all the resources in that particular environment. Hope this helps!
 
        
             
        
        
        
If we dont have enzymes then we would become malnourished as our body wouldnt be able to absorb the nutrients. Enzymes work in digestion to break down the food we eat
        
             
        
        
        
 
 Heat & Pressure ( So I guess in this answer choices it's " Heat up" )
The reason it's not " melt " because if melting were to take place then that would make Magma, and magma isn't metamorphic rock.
 
 
        
             
        
        
        
Answer:
I, II, III
Explanation:
A threshold stimulus is a stimulus that is capable to produce a response in excitable tissues such as neurons and muscle fibers. At threshold potential, the outward movement of K+ and inward movement of Na+ become equal to each other. When the potential exceeds the threshold potential, more and more Na+ enter the cell to depolarize it and to allow the opening of Na+ channels. Therefore, to fire an action potential, the threshold must be exceeded. 
Conduction of action potential is all or none phenomenon which means that either it occurs or it does not occur. As an impulse is passed by each successive part of an exon, it enters the refractory period during which there is no conduction of nerve impulse. It ensures the one-way conduction of impulse from the cell body to the axon terminal only.
