Most scientists describe biodiversity in terms of the number of species that have been discovered and described in scientific journals. roughly 1.8 million species have been described, although most scientists think there could be as many as 50 million species or more currently living on earth. however, in the video, craig venter seems more interested in the total number of discovered genes (he gives a total number of 20 million genes in the video) than the total number of discovered species. why is that?
a. for recombinant dna technology or for the creation of synthetic life, only the gene that produces a particular desired product is needed, and not the entire organism that carried the gene.
b. identifying species takes too much time, and the rules state that new species must be identified and described in a scientific journal before their genes can be studied.
c. he is not interested in entire organisms, since the entire genome of each one must be sequenced in order to find anything useful.
d. the microbes that the team is collecting are actually all the same species, but they each carry a unique set of genes.

The correct answer is option a. "For recombinant DNA technology or for the creation of synthetic life, only the gene that produces a particular desired product is needed, and not the entire organism that carried the gene".

Explanation:

Genetic biodiversity and population genetics are modern concepts related to the total number of discovered genes, which in the video Craig Venter explains that are around 20 million. The number of discovered genes are very important for scientific development because for recombinant DNA technology or for the creation of synthetic life, only the gene that produces a particular desired product is needed, and not the entire organism that carried the gene. Therefore, each new gene that is discovered or available, has the potential to be used in recombinant DNA technology developments.

type 2 happens when excess consumption of high-sugar foods flood the blood supply with glucose and reduce the production and effectiveness of insulin. if a person has prediabetes, they can reduce the risk of full diabetes through regular exercise and a balanced, low-sugar diet.

the truman doctrine was an american foreign policy whose stated purpose was to counter soviet geopolitical expansion during the cold war. it was announced to congress by president harry s. truman on march 12, 1947, and further developed on july 12, 1948, when he pledged to contain threats to greece and turkey.
