Which type of dna technology is used to caused bacteria to produce human insulin? a. recombinant dna b. pcr c. nuclear transfer d. gel electrophoresis

recombinant DNA

Choice A is correct

Explanation:

The type of DNA technology that is used to cause bacteria to produce human insulin is recombinant DNA.

Recombinant DNA is a technology developed by scientists which made it possible to inject a human gene into the DNA or the genetic material of a common bacterium

The higher the biodiversity of an Habitat, the more

sustainable it is. Also, lower biodiversity equals less sustainability.

Explanation:

The term “biodiversity” is a coined from the phrase “biological diversity”. Biodiversity can be defined as the richness and variety of life of genes, species and ecosystem.

Biodiversity tells us a lot about the health of the biosphere. The greater the variety of species, the healthier the biosphere is. Why is this? This is because;  the greater the species, the more links in food chains/webs.  Also, the more the genes, the better chances for survival through adaptation.

On the other hand, Sustainability of an ecosystem is the ability of that ecosystem to maintain its structure and function over time in the face of inescapable external stress(e.g deforestation, tornadoes, floods, pollution, etc).  

For an ecosystem, sustainability means maintaining ecological processes over long periods of time. These ecological processes includes evolution, food chains and webs, population dynamics, succession. e.t.c

So, if an ecosystem is able to maintain its structure and function over time in the face of external stress, it is said to be sustainable.

FURTHERMORE, The higher biodiversity in an ecosystem means that there is a greater variety of genes and  species in that ecosystem. A great variety of genes and species means that the ecosystem is better able to carry out

natural processes. The ecosystem will therefore have more genes and species to help it carry out these processes. For  example, there will be more species and more links in food webs, more plants to help  with the biogeochemical cycles and more genes available for succession and evolution.
