Which component is a protein fiber of the extracellular matrix?

Protein  collagen

Explanation:

Protein  collagen is made up of a matrix of carbohydrate and proteins which comprises protein collagen as a major component of extracellular matrix. Protein collagen assembles itself into long fibrils known as collagen fibril which is very essential for providing strength and structural integrity to the tissue. Collagen fibers are woven with proteoglycans which is further connected to the long polysaccharide backbone. The matrix also comprises of some protein connectors such as integrins, fibronectin molecules etc. which establish connection among themselves or the other elements of the matrix

Explanation:

The United States is a power hungry country with a popular of nearly 400 million people.

Providing power to such a large population, both cheaply and reliably is not easy and takes various forms of power plants and energy methods to make sure energy is available to everyone.

When it comes to using electric driven cars, it becomes unreliable, since most electric cars have a limited range and the United States being a large country cannot currently support this.

People would rather use their cars which can provide up to 500 miles of mileage than an electric car which hardly goes 100 miles.

However, the impact of increasing fossil fuels can negatively impact biodiversity in surrounding ecosystems. Increasing carbon monoxide in the air will only lead to degradation of plant and animal life.
