Answer:
The first one is the second one, and the second one is the third one.
Explanation:
Earth's atmosphere provides protection, breathing, and the cycling of elements to humans.
<h3>Relationship humans have with Earth’s atmosphere</h3>
The fundamental relationship between humans and nature is the ongoing exchange and change of resources, the service nature and humans provide to each other. Humans provide carbondioxide to the atmosphere whereas atmosphere provides oxygen for breathing.
It also provides nitrogen to the soil due to which plants produce amino acid and provides food to us. Earth's atmosphere such as ozone layer provides protection from ultraviolet radiation.

c removing salt and minerals
the process of desalination removes salt and minerals so water is safe to drink
A Biomass
This is because it is easily replenished naturally and over a short period of time but only if there is a large quantity of biomass available. If there is little biomass than it will be nonrenewable.
The answer is B, unicellular
<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
