Answer:
Myosin
Explanation:
Myosin are the major components of both muscle and non muscle cells in striated muscles which is responsible for contraction or movement that convert chemical energy (ATP) into mechanical work thereby generating force and movement.
During cellular movement , myosin filament will be the ones that are responsible for attaching and pulling the other filaments along because Myosin binds to actin at a binding site on the globular actin protein,it also have ATP binding sites which hydrolyses ADP to ATP , ATP binding causes myosin to release actin, which make actin and myosin to detach from each other thereby causing attachment and contraction of other filaments

The process in which green plants use sunlight to make their own food. 
Photosynthesis is necessary for life on Earth. 
Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide gas.
It is the number one source of oxygen in the atmosphere. 
 
        
                    
             
        
        
        
Answer:
I think the answer is the first option, more reliable and harder to use.
Explanation:
I think this because technology is expensive and the most reliable thing we have right now so the other options don't make sense.
 
        
                    
             
        
        
        
Answer:
It is true that one-toed horse of today steadily evolved from its five-toed ancestor.
Explanation:
- Evolution is the law of nature.There is a continuous process of evolution in each biological species in nature.
 - Similarly, horses had 5 toes millions of year back, but according to the theory of gradualism their use decreased and toes started fusing.
 - Now, its only one toe at present but the vestigial left over provides the solid evidence for the fact that horses had 5 toes in the past.
