The statement which best explains why carbon is present in so many kinds of molecules is because <u>it can form four covalent bonds.
<em /></u>It isn't rare on Earth, so A is incorrect. It has valence electrons, so C is incorrect. It cannot become an ion, so D is incorrect.<u>
</u>
<span>Prokaryotic organisms are always unicellular, but eukaryotic organisms are always multicellular.
the second option because pro are usually found in plants and euk in animals and humans

Answer:
Science has a central role in shaping what count as environmental problems. This has been evident most recently in the success of planetary science and environmental activism in stimulating awareness and discussion of global environmental problems. We advance three propositions about the special relationship between environmental science and politics: (1) in the formulation of science, not just in its application, certain courses of action are facilitated over others; (2) in global environmental discourse, moral and technocratic views of social action have been privileged; and (3) global environmental change, as science and movement ideology, is vulnerable to deconstructive pressures. These stem from different nations and differentiated social groups within nations having different interests in causing and alleviating environmental problems. We develop these propositions through a reconstruction of The Limits to Growth study of the early 1970s, make extensions to current studies of the human/social impacts of climate change, and review current sources of opposition to global and political formulations of environmental issues.
Answer:
What does cellular respiration due?
<h2>Cellular respiration releases stored energy in glucose molecules and converts it into a form of energy that can be used by cells.</h2>
Explanation:
<h2>What are the 7 steps of cellular respiration in order?</h2>
<h2>Overview of the steps of cellular respiration. Glycolysis. Six-carbon glucose is converted into two pyruvates (three carbons each). ATP and NADH are made.</h2>
...
<h2>Glycolysis. ... </h2><h2>Pyruvate oxidation. ... </h2><h2>Citric acid cycle. ... </h2><h2>Oxidative phosphorylation</h2>
<h2>Answer</h2>
<h2> Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules[1] or nutrients into adenosine triphosphate (ATP), and then release waste products.[2] The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy because weak high-energy bonds, in particular in molecular oxygen,[3] are replaced by stronger bonds in the products. Respiration is one of the key ways a cell releases chemical energy to fuel cellular activity. The overall reaction occurs in a series of biochemical steps, some of which are redox reactions. Although cellular respiration is technically a combustion reaction, it clearly does not resemble one when it occurs in a living cell because of the slow, controlled release of energy from the series of reactions.Nutrients that are commonly used by animal and plant cells in respiration include sugar, amino acids and fatty acids, and the most common oxidizing agent providing most of the chemical energy is molecular oxygen (O2).[1] The chemical energy stored in ATP (the bond of its third phosphate group to the rest of the molecule can be broken allowing more stable products to form, thereby releasing energy for use by the cell) can then be used to drive processes requiring energy, including biosynthesis, locomotion or transport of molecules across cell membranes.</h2>
