The answer is A) less than 2.9
Answer:
Petrified fossils
Explanation:
Petrified fossils is the method of fossilization that preserves the most detail of an organism. Petrified fossils are formed when minerals replace all or some part of once-living matter.
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.
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. ... Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy.
