Answer: Number 2, aka Solid wastes on land.

Explain the water cycle using the terms condensation, evaporation, and precipitation.
RideAnS [48]

Answer:

The water cycle is also known as the hydrological cycle. It shows how water is circulated continuously within the atmosphere of the Earth.

Evaporation is the process where water, when heated, goes from the liquid to gaseous state in the form of vapor. This is how water gets from the geosphere to the atmosphere. As the vapor rises, the air around it gets cooler, and this is where condensation occurs. Condensation is the process where vapour will turn into its liquid state. As more vapour condense they start to form clouds. When the cloud gets dense enough, the water falls back to Earth through precipitation.

<h2>Capillary Smooth Muscle Contraction</h2>

Explanation:

  • Blood flows through blood vessels, which form the closed system called the circulatory system. Like a system of roads, the circulatory system has its highways, back roads, and alleyways, which we call arteries, veins, and capillaries
  • Capillaries are the alleyways that extend and branch into every tissue of your body, ensuring that every cell has a blood supply. It is here, in the capillary beds, that your cells pick up oxygen and nutrients and drop off carbon dioxide and wastes
  • Muscles are composed of two major protein filaments: a thick filament composed of the protein myosin and a thin filament composed of the protein actin. Muscle contraction occurs when these filaments slide over one another in a series of repetitive events
  • All muscles contract as a result of interaction between special proteins within the myocytes. Skeletal, cardiac, and smooth muscle cells synthesize the contractile proteins actin and myosin, which are needed for muscular contraction
