almond37 [142]

Fibrin is an insoluble component of plasma that forms a meshwork of strands and is considered the structural basis of clot formation.

<h3>What is clot formation?</h3>
  • Blood turns from a liquid to a gel during coagulation, which results in the formation of blood clots.
  • Possible outcomes include haemostasis, which stops blood loss from a broken vessel, followed by repair.
  • The activation, adhesion, and aggregation of platelets, as well as the deposition and maturation of fibrin, are all components of the coagulation process.
<h3>What is fibrin?</h3>
  • A fibrous, non-globular protein called fibrin is necessary for blood to clot.
  • It is created when fibrinogen undergoes polymerization due to the protease thrombin.
  • A haemostatic plug or clot is formed over a wound site by platelets and polymerized fibrin.

Earth has a great variety of surface features that are caused by weathering and erosion. Which of the following describes a chan
Sidana [21]

Answer:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

 

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

 

Weathering and erosion constantly change the rocky landscape of Earth.
