Answer:
Transposition to different chromosomes by the ancestral gene
Explanation:
Transposable Elements (TEs), also known as jumping genes, are genetic mobile elements which are able to move from one location to another on the genome. There are two major mechanisms of TE transposition: 1-cut-and-paste mechanism, where one particular TE is inserted into a new position on the genome without replication, and 2-copy-and-paste mechanism, where a new copy is generated and the original TE remains at the original genomic site. In this case, it is likely that new TE copies containing the ancestral (duplicated) gene have proliferated through the copy-and-paste mechanism.

<span>Osmosis differs from the process of diffusion in that osmosis concerns only the movement of</span> water and is always the movement in the membrane. Diffusion does not need a membrane to make molecules and Diffusion is the movement of molecules.
Answer: answer 1 and 3 only
Explanation:
Spiders not from the US can potentially take over other species habitats. Same with flowers not from a specific area.
Among the choices presented above, the statement "Butterflies eat nectar from flowers" can be called a direct observation. An observation is the term given to the process of acknowledging and recognizing the facts found around the surroundings. In most times, the observation are expressed by the use of the five senses of man, the sense of smelling, the sense of sight, the sense of tasting, the sense of touch, and the sense of hearing. Observations can either be qualitative and quantitative.
