Metagenomics is used to analyse the genetic diversity of microorganisms only in aquatic ecosystems.

FALSE

TRUE

The discovery of DDT's impact on the eggshells of American bald eagles in the mid-twentieth century was unrelated to the development of ecotoxicology as a scientific field.

FALSE

TRUE

Metabolomics focuses on the analysis of genes involved in the cell's energy production.

TRUE

FALSE

The application of omics technologies to aquatic ecosystem is related to:

Assessment of global molecular responses before pollutants exposure

Assessment of a single molecular response to pollutants exposure

Assessment of a single molecular response before pollutants exposure

Assessment of global molecular responses to pollutants exposure

Which of the following statements is true about omics technologies?

Omics techniques always require multiple samples for each analysis.

Genomics, the study of the genome, was the starting point for omics technologies.

Proteomics involves the analysis of nucleic acids within the cell.

Transcriptomics cannot be performed using complementary DNA libraries.

Which of the Omics technologies is used to identify and quantify proteins in a cell?

Metabolomics

Genomics

Transcriptomics

Proteomics

Omic technologies are used only in human health research.

TRUE

FALSE

Metabolite profiling can show the effects of environmental stresses on the organism.

TRUE

FALSE

Ecotoxicology combines the fields of toxicology and ecology to identify, analyse, and predict the effects of environmental pollutants on living organisms and ecosystems.

TRUE

FALSE

Ecotoxicology is an applied science that:

Analyses only chemical pollutants in industrial areas.

Combines toxicology and ecology to study environmental pollution and its effects.

Examines the interaction of organisms within their ecosystems without considering pollutants.

Focuses only on the effects of toxic substances on humans.
