Answer:
Air pollution harms human health and the environment. In Europe, emissions of many air pollutants have decreased substantially over the past decades, resulting in improved air quality across the region. However, air pollutant concentrations are still too high, and air quality problems persist. A significant proportion of Europe’s population live in areas, especially cities, where exceedances of air quality standards occur: ozone, nitrogen dioxide and particulate matter (PM) pollution pose serious health risks. Several countries have exceeded one or more of their 2010 emission limits for four important air pollutants. Reducing air pollution therefore remains important.
Air pollution is a local, pan-European and hemispheric issue. Air pollutants released in one country may be transported in the atmosphere, contributing to or resulting in poor air quality elsewhere.
Particulate matter, nitrogen dioxide and ground-level ozone, are now generally recognised as the three pollutants that most significantly affect human health. Long-term and peak exposures to these pollutants range in severity of impact, from impairing the respiratory system to premature death. Around 90 % of city dwellers in Europe are exposed to pollutants at concentrations higher than the air quality levels deemed harmful to health. For example, fine particulate matter (PM2.5) in air has been estimated to reduce life expectancy in the EU by more than eight months. Benzo(a)pyrene is a carcinogenic pollutant of increasing concern, with concentrations being above the threshold set to protect human health in several urban areas, especially in central and eastern Europe.
"Air pollution is causing damage to human health and ecosystems. Large parts of the population do not live in a healthy environment, according to current standards. To get on to a sustainable path, Europe will have to be ambitious and go beyond current legislation."

Answer:
Incomplete dominance
Explanation:
Incomplete dominance is a condition observed in the organisms while studying their genetics.
When the organisms with two alleles for the same trait are crossed, then neither of the two alleles completely express themselves but a new variation of the trait is formed.
This can be observed in the given scenario also when the ed and white flowers are crossed, then the pink flowers (a new variation of the trait) is formed called blended trait.
Thus, incomplete dominance is correct.
Answer:
2
Explanation:
that is what evolution says
Answer:
DNA: ACT TTC GAT
mRNA: UGA AAG CUA
tRNA: ACU UUC GAU
AA: stop-lysine-leucine
Explanation:
mRNA is the complementary sequence of the DNA strand and tRNA is a complementary sequence of mRNA sequence. mRNA is a sequence of bases that is formed by encoding the DNA sequence in the complementary pattern during transcription.
tRNA is complementary of the mRNA code to produce the amino acid which is decided by the codon ( a three- base sequence of mRNA) what amino acid be present in what sequence.
Thus,
DNA: ACT TTC GAT
mRNA: UGA AAG CUA
tRNA: ACU UUC GAU
AA: stop-lysine-leucine (however, after the stop codon amino acid chain terminated in any protein)
