AfilCa [17]

Answer:

Answer is E. Apply a thin layer of lotion on the skin from the neck to the soles of the feet.

Explanation:

Scabies are described or known to be small bugs that burrow and  found crawling under the skin. They lay eggs and continue to multiply under the skin.

They cause rash on the skin and severe or intense itching, which normally get worse in the night.

The lindane lotion , when applied on the skin, goes through or enters the skin, and kills the scabies and their eggs.

The scabies do not affect the face of adults and older children.

Do all living tissues contain catalase? Claim, evidence, and reasoning
allsm [11]

Yes, the all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.

<h3>Do all living tissues contain catalase?</h3>

Catalase is a common antioxidant enzyme which is present in all living tissues of an organism and it is responsible for the degradation or reduction of hydrogen peroxide to water and molecular oxygen using either iron or manganese as a cofactor.

Liver, potatoes and other living tissues contain the enzyme catalase. This enzyme breaks down hydrogen peroxide which is a harmful by-product of the process of cellular respiration. If it builds up in concentration in the cells, the cells are adversely affected which leads to serious complications in the organisms.

So we can conclude that all living tissues contains the catalase, Catalase protects cellular organelles and tissues from damage by peroxide.

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."
