Areporter gene--that is, a gene whose activity is relatively easy to detect--is commonly used to study promoter activity under a variety of investigative circumstances. recombinant dna technology is used to attach such a reporter gene to the promoter of interest, after which the recombinant molecule is inserted by transformation or transfection into the cell or host organism of choice. green fluorescent protein (gfp) from the jellyfish aequorea victoria fluoresces green when exposed to blue light. assume that you wished to study the regulatory apparatus of the lac operon and you developed a plasmid (p) that contained all the elements of the lac operon except that you replaced the lac structural genes with the gfp gene (your reporter gene). you used this plasmid to transform e. coli.

explanation:

the panel also concluded there's a better than 95 percent probability that human-produced greenhouse gases such as carbon dioxide, methane and nitrous oxide have caused much of the observed increase in earth's temperatures over the past 50 years.

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.

maybe because its impossible for balloons to lift a whole entire house.
