Answer:
The term “reptile” is derived (Made) from a Latin word meaning “creeping animals.” These animals include snakes, lizards, crocodiles, alligators, turtles, geckos, and chameleons, with lizards and snakes species making up the majority of all reptiles. Reptiles are cold-blooded animals which means they are unable to regulate their own body temperature. Reptiles are Oviparous (Egg laying). Reptiles also have chains of bony elements from the tail to the head. The bony endoskeleton consists of cranium or skull, appendages, and limb girdles. The endoskeleton protects the inner tissue and also aids in body movement. Skeletons differ from one species to another, with crocodiles having some of the largest body structures in this class.

I think it is keystone.  If they were not there the population of urchins would go up and the kelp would go down.
        
                    
             
        
        
        
Answer:
2, 4, and 5 refers to scientific revolution while on the other hand, the remaining statements shows scientific observation.
Explanation:
Cloning has the potential to  significantly benefit a great many  people, so it should not be  considered immoral or risky is refers as scientific observation.
A scientist thinks that he might  find serious inconsistencies in the  fossil record if he conducts an  excavation in a new location is refers scientific explanation because explanation is needed for it which can drawn from the scientific observation.
The rocks present in western Africa  and eastern South America formed  at the same place and at the  same time is scientific observation because the scientists takes the data.
Even if modern organisms are  found in ancient portions of the  fossil record, this wouldn't challenge the theory of evolution in any way is refers to scientific explanation.
The cloning of organisms is an  exciting area of study, and more  resources should be be devoted  to it so it is refers as scientific explanation.
The age, type, and composition of  ancient rocks in western Africa are  nearly identical to the age, type,  and composition of rocks in  eastern South America is scientific observation which is taken by the scientist through research.
