Answer:
Distinct mechanisms are used by bacteria in order to transfer the gene from one bacteria to another. These are transformation, transduction, and conjugation. Transformation refers to the process of uptaking extracellular DNA by the recipient of the other bacterial cell.
In the process of transduction, the donor DNA gets packed within the bacteriophage and infects the recipient bacteria. In the process of conjugation, the genetic substance is transferred by the donor bacteria to the recipient via the process of mating.
a. Of all these three mechanisms, transformation is the process that exhibits a broad range and can be easily performed in the lab. As in the process, there is a slight chance of rejection or failure due to direct compatibility between the bacteria.
b. While the narrowest broad range is found in the process of conjugation, as in order to transfer the genetic substance between the two bacterial species, there should be a similarity between the two species so that they can mate and exchange the genetic substance in between them.
<h2>Answer is option " 2 & 4"</h2>
Explanation:
- Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:
- m+g/mg : Parental
- mg+/mg : Parental
- m+g+/mg : Recombinant
- mg/mg : Recombinant
- m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
- Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"
Highly porous and permeable
Explanation:
Compared to other types of rock layers, an aquifer is highly porous and permeable.
Aquifers are always the target when prospecting for ground water in a formation.
- Porosity is the amount of void spaces in a rock.
- Aquifers are highly porous .
- Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
- Aquifers have very high permeability compared to other rock types.
In terms of permeability and porosity, an aquifer is higher porous and permeable.
