Photosynthesis has a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur.
 
        
             
        
        
        
Answer:
The hellbender, which is much larger than all other salamanders in its geographic range, employs an unusual means of respiration (which involves cutaneous gas exchange through capillaries found in its dorsoventral skin folds), and fills a particular niche—both as a predator and prey—in its ecosystem

Answer:
Organs
Explanation:
Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body. Many organs working together to accomplish a common purpose is called an organ system.
 
        
                    
             
        
        
        
Answer:
The correct answer:
1. 100 × 35/100 ⇒ 35% of 100 (2nd and 7th)
2. 200 × 25/100 ⇒ 25% of 200 (4th and sixth)
Explanation:
As it is given that and we know that 25% of 200 can be calculated by multiplying the principle value which is 200 to percentage value divided by 100 (100 is whole value).
Similarly, we can found the calculative representation of 25% of 200 and 35% of 100 are only two values that can be put in boxes after the arrow that are:
1. 100 × 35/100 ⇒ 35% of 100
2. 200 × 25/100 ⇒ 25% of 200
 
        
             
        
        
        
They unite to form a zygote then an embryo. Most produce both male and female gametes.
