The rapidity and cost-efficiency of dna sequencing has made it possible to sequence virtually all of the genes present in the microbes of a given habitat. this generates a collective genome for that habitat, which has come to be called a(n)

Meta genome.

Explanation:

The collective genome for that habitat, has come to be called as Meta genome.

Meta genomics is the study of genetic material recovered directly from the environmental samples. It is the DNA sequencing of the any organism at their habitat is done through Meta Genome. It is also called as ecogenomics and community genomics.

i really wish i could answer this question for you

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
