The period during which the presence of stromatolites decline is the Proterzoic period. Stromatolites are widely distributed sedimentary structures consisting of laminated carbonate or silicate rocks, produced over geologic time by the trapping, binding, or the precipitating of sediment by groups of microorganisms, primarily cyanobacteria.
The rest are incorrect:Bath salts can produce anxiety, agitation, hallucinations, and paranoia even in low doses, not just when used at high doses.Bath salts cannot cause a rapid drop in blood pressure and heart rate, instead it causes rapid increase when ingested, snorted, or injected.Bath salts are not synthetic drugs like mdma (methylenedioxy-methamphetamine).
The answer is greenhouse effect
Answer:
by phenotypically identifying plants unable (or with an altered ability) to synthesize auxins. This approach is called reverse genetics
Explanation:
Reverse genetics is a strategy widely used in molecular genetics aimed at analyzing the function of target genes by identifying defective phenotypes of one or more organisms following the disruption of the gene. In this case, a mutagenesis approach (i.e., irradiation with X-rays) was used to induce mutations in the gene/s involved in auxin production. Subsequently, the resulting mutant phenotypes, i.e., plants with an altered ability to synthesize auxin, can be used to reveal the biological function of individual (mutated) gene sequences.
