<span>Mutation cannot be predicted and research cannot determine when mutations will occur. However, natural selection indicates that species with the strongest traits will multiply more and live longer than their weaker counterparts. Therefore natural selection is systematic and predictable.</span>
The right option is; D) It has high-energy phosphate bonds
ATP contains a large amount of energy because it has high-energy phosphate bonds.
Adenosine triphosphate (ATP) is an organic molecule that performs important roles as an energy transport molecule, a phosphate donor, and a signaling molecule within cells. ATP is made up of adenosine (an adenine ring and a ribose sugar), and three phosphate groups. ATP is an unstable molecule which hydrolyzes when it react with water to form ADP (adenosine diphosphate) and inorganic phosphate. The large amount of energy of ATP comes from the two high-energy phosphate bonds.
Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability.
Answer:
A. 8
Explanation:
The 2s subshell holds a maximum of 2 electrons, and the 2p subshell holds a maximum of 6 electrons. Which means that the second shell can hold a maximum of only 8 electrons (2+6 = 8)
Simple carbohydrates consist of one or two sugar basic units; while complex carbohydrates are polysaccharide chains of simple sugars.
<h3>Carbohydrates </h3>
Usually with a hydrogen-oxygen atom ratio of 2:1 (as in water), a carbohydrate is a biomolecule made up of carbon (C), hydrogen (H), and oxygen (O) atoms. As a result, it has the empirical formula Cm(H2O)n (where m may or may not be different from n). However, not all compounds that do adhere to this precise stoichiometric criterion are automatically categorized as being carbohydrates (e.g., uronic acids, deoxy-sugars like fucose, and uronic acids do not correspond to this definition) (e.g. formaldehyde and acetic acid).
The word is most frequently used in the context of biochemistry where it is used as a shorthand for the term saccharide, which refers to a class of substances that includes sugars, starches, and cellulose. The four chemical subgroups of saccharides are monosaccharides, disaccharides, oligosaccharides, and polysaccharides.
