Answer:

C. Platelet adhesion

Explanation:

Platelet adhesion comes first in the process of hemostasis.

The process of hemostasis has got three phases:

  • Vascular spasm
  • Platelet plug formation
  • Blood coagulation

The process occurs in the body in the event of a bleeding injury.

In the first phase, damaged blood vessels constrict to prevent more bleeding.

In the second phase, platelets adhere to damaged endothelium to form platelet plug.

In the third phase, fibrinogen is converted to fibrin to form a clot.

A cylinder fits inside a square prism as shown. For every cross section, the ratio of the area of the circle to the area of the
dedylja [7]
Area circle = π*r²

Area square = l²

The side of the square is equal to the diameter of the circle

Area square = D²

A diameter is always twice the radius

Area square = (2r)² = 2²r² = 4r²


So this is the rate:

Area circle/Area square = (π*r²)/(4r²)

Area circle/Area square = π/4


Volume is always Area*h when cross sectional area is a constant

Volume Prism = Area Square*h 

Volume Prism =  4r²*h

Volume Cylinder = Area Circle*h

Volume Cylinder = π*r²*h

So far this is option D)


Let’s calculate the rate:

Volume Cylinder/Volume Prism = π*r²*h/4r²*h

Volume Cylinder/Volume Prism = π/4

Volume Cylinder = π/4* Volume Prism

This is also option D)


Now let’s calculate Volume Cylinder from that formula:

<span>Volume Cylinder = π/4* Volume Prism</span>

Volume Cylinder = π/4 *(4r²*h)

<span>This is also option D)</span>

<span>
</span>

<span>So option D) is correct</span>

How do volcanoes function as a disruptive force? Check all that apply.
cluponka [151]

Answer:

- force people to flee their homes

- cause massive earthquakes

- pollute the air with volcanic smoke

- make airplanes fly around ash clouds

Explanation:

The volcanoes can be seen as both creative and disruptive force. The disruptive side of the volcanoes includes numerous things. Because of the big pressure that the volcanoes make on the crust, it is very common that they create earthquakes, some being very strong. They release enormous amounts of gases, ash, and pyroclastic material, resulting in pollution of the air. The gases and ash can stay in the atmosphere for longer period of time, as well as travel over long distance, making the airplanes change their routes and go around them, or stop their flights until the air clears out. The volcanic eruptions themselves are very dangerous for the people, be it calm with lava flows, or with explosive eruptions, the people a forced to flee their homes and leave everything behind in order to save their lives.
