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.

While we usually think of fever as a bad thing, a fever is actually signifying that an immune response is progressing! Overall,
zalisa [80]

Answer:

E. Interleukin-1

Explanation:

Interleukin-1 is produced by macrophages and is involved in promoting the proliferation of helper T cells. Interleukin-1 also acts on the hypothalamus to cause fever. Fever refers to abnormally high body temperature. During infection and inflammation, the hypothalamic thermostat is reset in response to interleukin-1 resulting in fever. The presence of certain bacterial toxins in the body triggers the release of interleukin-1 from macrophages and the body temperature is elevated. Fever inhibits the growth of some microbes, intensifies the effects of interferons, and stimulates the body's immune reactions.

Explain how ecosystem can change even if people are not involved​
andrew11 [14]

Answer:

The animals could change it. For example, a bunny could dig a hole in the ground, making a home for other animals inside of it, too, changing the animals' living environment.

Or natural disasters could change their environment, too. For example, if a landslide occurred and covered a pond, frogs and snakes could lose their living areas and food, which would make them have to move to a different area, changing another ecosystem.
