<h2>Answer:</h2>

<u>Atom</u> is the primary as well as smallest unit of element.

<h2>Explanation:</h2>

Atoms are the tiny blocks that build elements. They are composed of proton, electron, and neutron. The electron is negatively charged, protons are positively charged, and neutrons are devoid of any charge.

The atom present in the elements combine with one another and leads to the formation of molecules. The property of the atom remains unchanged even after involved in formation of new molecules. When two atoms combine together it is called as molecules.

Explanation:

These five major trends pose a major global threat to the planet. If the world is to maintain the habitat of humans and other species. These environmental problems must be resolve. DW discussed the reasons and possible solutions.

Air pollution and climate change

Problems

Carbon overload in the atmosphere and seawater. The CO2 in the atmosphere absorbs and re-emits infrared wavelength radiation. Which causes the air, soil, and ocean surface water to warm. Which is a good thing without this, the earth would freeze. Unfortunately, there is too much carbon in the air now.

The burning of fossil fuels, agricultural deforestation, and industrial activities have increased the concentration of carbon dioxide in the atmosphere from 280 parts per million (ppm) 200 years ago to about 400 pm today. Whether it is scale or speed, this is unprecedented growth. The result: a change in the climate.

Carbon overload is just one form of air pollution caused by burning coal, oil, natural gas, and wood. The World Health Organization recently estimate that one in nine deaths in 2012 were caused by diseases caused by carcinogens and other poisons in the polluted air.

Solution:

Replace fossil fuels with renewable energy. Forest restoration. Reduce agricultural emissions. Changing industrial processes, The good news is that clean energy is abundant, but it needs to be harvest.

Many people say that it is feasible to use existing technologies to achieve a 100% renewable energy future, but the bad news is that even though renewable energy infrastructure (solar panels, wind turbines, energy storage, and power distribution systems) are widely available and Become cheaper and more efficient.

Experts have always said that our applications are not fast enough to avoid catastrophic climate damage.

Deforestation

Problem

Species-rich wild forests are destroye, especially in tropical areas. Usually to make way for cattle farms, soybean or palm oil plantations, or other monocultures. Today, about 30% of the earth’s land area covers by forests.

This is about half of what it was before agriculture started about 11,000 years ago. Approximately 7.3 million hectares (18 million acres) of forest are destroyed every year, mainly in the tropics. Therefore Tropical forests used to account for about 15% of the earth’s land surface; now they have fallen to 6% or 7%.

Solution

Most of the remainder has degraded by logging or burning. Natural forests are not only a reservoir of biodiversity but also a carbon sink. Excluding carbon from the atmosphere and ocean.

Therefore Restore degraded areas by replanting native tree species. This requires strong governance. But many tropical countries are still developing, their populations are growing. So that The rule of law is unbalanced, and cronyism and bribery are common in allocating land use.

daser333 [38]

Answer:

Blood cells

Explanation:

Hypocapnia refers to a situation whereby carbon dioxide is at a reduced level in the blood. This phenomenon is usually caused by deep/rapid breathing known as hyperventilation.

It signals a breakdown in the exchange of gases inside your blood cells where the stuff your body doesn’t want is swapped out for the stuff it desperately needs.
