A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), from animals to plants and microorganisms. Genes have been transferred within the same species, across species (creating transgenic organisms) and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered or knocked out.
Answer
The 4 events that occur during amoeba are:-
- It sees the food particle.Then by pseudopodia (the finger like projections from amoeba) traps the food particle.
- The finger-like extensions of the cell surface fuse over the food particle forming a food vacuole.
- Inside the food vacuole, complex foods are broken down into simpler ones which then diffuse into the cytoplasm.
- The remaining undigested material is moved to the surface of the cell and thrown out. [Egestion].
Answer:
nitrogen fixation.
Explanation:
Nitrogen fixation is the process by which the combination of molecular nitrogen oxygen or hydrogen is given to give oxides or ammonium that can be incorporated into the biosphere. Molecular nitrogen, which is the majority component of the atmosphere, is inert and not directly usable by most living beings.
