The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

The diagram shows the five kingdoms of life. The place where the circles intersect include
Dimas [21]
Well it’s not the prokaryotes because that’s bacteria and archaea. Eukaryotes is your best bet because the two do fall under that category.

When it comes to the multicellular or unicellular protists are MAINLY unicellular while plante, animalia and fungi only are all multicellular so if they were in the same circle that’s probably while they are separated in the first place.

I would pic eukaryotes!
Hope this helps!

Answer:

muscles

ribs

lungs

bronchioles

alveoli

diffuses

leaves

exchange

Explanation:

Your diaphragm, and <u>muscles</u> between your <u>ribs</u>, make air move in and out of your <u>lungs</u>. It travels through the trachea, bronchi, and <u>bronchioles </u>to <u>alveoli</u>. In the alveoli, oxygen <u>diffuses</u> into the blood and carbon dioxide<u> leaves</u>. This is gas <u>exchange</u>.

<em>Air enters the lungs and leaves it as a result of the relaxation and contraction of the diaphragm and the muscles between the ribs. When both the muscles and the diaphragm relax, air enters from the trachea and travels through the bronchi and the bronchioles to the alveoli, where the oxygen in the air diffuses into the blood and carbon dioxide diffuse in the opposite direction. The entire process is known as gas exchange.</em>

Federal and state environmental rules cover air quality, water quality, waste management, land conservation, chemical and oil spills, drinking water quality. Some environmental policies regulate the actions of private individuals, organizations, or businesses. For example, a factory that must discharge wastewater as part of its daily operations may need to hold and maintain a federal permit. The factory would be required to follow a set of rules and requirements within its permit to comply with environmental laws. </h2><h2 /><h2>Environmental rules and regulations vary in their requirements depending on issue involved. Environmental policy and energy policy are also interconnected. For example, energy production and consumption can produce environmental effects. As a result, environmental policy can involve restrictions or regulations on energy production such as oil and natural gas operations or solar energy development.</h2><h2>____________________________________</h2><h2>so that means the answer is reduce the use of natural resources</h2><h2>____________________________________</h2><h2>hope this helps have a good day  :):):):):):):):):):)</h2><h2>                                Goodbye</h2>
