In community, two species A and B were found. A species have an especially large impact on the structure of entire communities because they are highly abundant while B species are not usually abundant in a community however; exert strong control on community structure by their pivotal ecological roles, or niches.

 Many mouse genes are “tissue-specific,” that is, they are present throughout the body but are expressed in only one of the animal’s many tissue types. (Other mouse genes are expressed throughout the body, or in multiple tissues.) Geneticists can study the regulation of a mouse gene by fusing the gene’s promoter region to the LacZ coding sequence and injecting the construct to create a transgenic mouse. Fusion of the mouse amylase promoter to LacZ yielded a Pamylase-LacZ construct.              

Mice heterozygous for the resulting Pamylase-LacZ  transgene displayed the LacZ expression exclusively in the pancreas. Would you expect homozygotes for the transgene to also display LacZ expression in the pancreas?.

BLAST uses heuristics to align a query sequence with all sequences in a database. 

Reason(R): BLASTX uses protein sequences as queries to search against a protein sequence database.
