Building blocks are the small units that make the larger, more complex molecule. The building block of protein is an amino acid and lipids are fatty acids and glycerols.
<h3>What are proteins and lipids?</h3>
Proteins and lipids are the biomolecules that are involved in major reactions in the living system. They are composed of smaller subunits joined together by bonds.
Proteins are molecules made up of amino acids linked by the peptide bonds to form the chain of proteins that plays a crucial role in cell functioning.
Lipids are composed of fatty acids and glycerol linked by the ester bond, essential for the storage of energy and in the composition of the membranes.
Therefore, proteins are composed of amino acids and lipids of fatty acids and glycerol.

Answer:
Explanation:
<u>1. Oxidation half-reaction (given)</u>
- 2S₂O₃²⁻ (aq) → S₄O₆²⁻ + 2e⁻
<u>2. Reduction half-reaction:</u>
Reduction is the gain of electrons with the consequent reduction in the number of oxidation.
The starting reactant is iodine which is diatomic; thus, it is I₂.
Each iodine atom gains one electron; thus, in total 2 electrons are gained and each I atom in solution will become an I⁻ anion.
Half-reaction:
- I₂ (aq) + 2e⁻ → 2I⁻(aq) ↔ answer
The overall reaction of thiosulfate anion with iodine is obtained when you add the two half-reactions:
- 2S₂O₃²⁻ (aq) → S₄O₆²⁻ + 2e⁻
===============================
(the electrons are canceled)
- 2S₂O₃²⁻ (aq) + I₂ (aq) → S₄O₆²⁻ + 2I⁻(aq)
The answer is: D. Biological precipitation.
Biological precipitation is the deposition of minerals from solution by the agency of organisms
.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass.
Ocean sediments originate from numerous sources:
1) biological activity (biogenous).
2) weathering and erosion of the continents (terrigenous/lithogenous).
3) volcanic eruptions (volcanogenous).
4) chemical processes (hydrogenous).
Calcium carbonate (CaCO₃) is made of calcium, carbon and oxygen atoms.
