The burrowing owl is found in dry, open areas such as grasslands, prairies, savannas, deserts, farmlands, golf courses, and other urban areas throughout most of western united states and florida, central america, and most of south america. it makes its home in burrows of other animals and primarily eats insects and small rodents. as humans build more cities, nearby burrowing owl habitats change due to destruction of burrows and loss of prey. which is the least likely outcome of the habitat changes that are described?

the niche of the burrowing owl may change as it adapts to the changes.
the niche of the burrowing owl may change as it moves to a new habitat.
the population of the burrowing owl may be reduced or even become extinct. the population of the burrowing owl may increase in its new surroundings.

this protocol provides a detailed procedure for total protein extraction for western blot analysis from achieved samples following trizol isolation of rna.

hello there the answer is d

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
