Answer:
Genetic engineering is deliberate modification of genome to gain desired traits.
The main steps of genetic engineering:
Restriction enzymes are used to isolate the required gene leaving it with sticky ends. Sticky ends are a short section of unpaired bases A vector, which is usually a bacterial plasmid or a virus, is cut by the same restriction enzyme leaving it with corresponding sticky ends. The vector and the isolated gene are joined together by ligase enzyme. The vector inserts the gene into required cells. The genes are transferred to animal, plant or microorganism cells, during early development, which allows them to develop with the desired characteristics.
An element is the simplest form of matter that has a unique set of properties. Examples of well-known elements include oxygen, iron, and gold (see the figure below). Elements cannot be broken down into a simpler substance.

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.
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.
