Most responsible for the turn-around in water quality in Lake Washington is option c) regulations on sewage treatment.
<h3>What does sewage treatment mean?</h3>
To prevent water pollution from discharges of raw sewage, sewage treatment is a sort of wastewater treatment that tries to remove contaminants from sewage to generate an effluent that is appropriate for discharge to the surrounding environment or an intended reuse application. Sewage includes pre-treated industrial effluent as well as wastewater from homes, companies, and possibly other sources. There are many different sewage treatment methods available.
Decentralized systems (including on-site treatment systems) and huge centralized systems that transport sewage to a treatment facility via a network of pipes and pump stations are examples of these. Urban runoff (stormwater) from cities with combined sewers is also transported by the sewers to the sewage treatment facility. Sewage treatment often involves two main stages, called primary and secondary treatment.

Answer:
A. Only L-amino acids (except for glycine) are used in proteins.
B. The partial double bond character of the α-C-N bond in the peptide group limits the conformations of the peptide group.
C. Hydrogen bonding within elements of secondary structure stabilize certain atomic geometries.
D. Although any one of 20 amino acids is possible at each position, only one is used.
Explanation:
Proteins are biomolecules composed of one or more chains of amino acid residues which are joined together by peptide bonds (this sequence represents the primary structure of the protein). Proteins are made up of 20 types of amino acids which have diverse properties. The secondary structure of a protein refers to the local structure of the protein backbone, which is stabilized by hydrogen bonding between amino groups (—NH2) and carboxyl groups (—COOH) in neighboring areas of the protein. The most common secondary structures in proteins include alpha helices, beta sheets, and random turns. Moreover, the tertiary structure in proteins describes the packing of these secondary structures. The peptide bond (CO–NH) is a stable covalent bond that has a rigid planar structure and acquires partial double-bond properties, thereby peptide bonds undergo very little rotation (i.e., rotation around peptide bonds is restricted). With the exception of glycine, all amino acids are stereoisomers, i.e., there exist mirror images of their structures which are labeled as L (left-handed) and D (right-handed) in order to differentiate between mirror images. All amino acids in proteins have the L-configuration.
Answer:
A friend is someone who is there for you when you need them and cares for you. Friends should support you on almost everything, except if your doing something bad or anything like that.

Answer:
Most people believe that drinking milk can soothe heartburn.
Explanation:
Pseudoscience refers to practices and beliefs that are believed to be scientific but in actuality, do not follow any known scientific method. Even after it has been logically proven that these practices have no scientific backing people continue to believe in them because through confirmation bias, they believe that they work.
True science is evidence and research-based. Pseudoscience as seen in the last option is just based on belief.
