The answer to this question is:
a.
Phosphorus
This is one of the topmost elements needed by living
organisms. It is not a pure element but reactive to anything in contact. When
combined with some other elements it serves as necessity of life. It is present
in plants or animals in less than 1%.

Answer:
Continued human development and natural resource abuse lessen the amount of wilderness, affecting the Florida panther particularly negatively due to its requirement for large territories.
The correct answer is option B, that is, electroporation succeeded by recombination.
A usual method of presenting exogenous nucleic acids into cells is known as electroporation. In this, an electric voltage potential is used through a biological membrane, ultimately resulting in the formation of conducting hydrophilic pores. The process of electroporation is utilized for transporting or transfecting nucleic acids generally DNA within the cells, to make them articulate genes that would modify the genetic mechanism.
The transfected DNA can get recombined or incorporated into the host genome or can remain in its own composition. Thus, the process of electroporation straightforwardly permits more recombination to take place.
