Answer:

Fibrous

Explanation:

Proteins are assembled according to their functions. Fibrous proteins usually provide protection and support to cells. They are made up of polypeptides that have elongated shape and assembles in large cables or threads. These proteins are differentiated from globular proteins by their globular form and repeated units of amino acids.

For example the fibrous proteins involved in horns, hair and nails is alpha-keratin.  Elastin found in skin and ligament is also a fibrous protein. Collagen includes collagen fibrils that have tensile strength of steel is also a fibrous protein found in cartilages and bones.

How do the structures in an organism relate to their functions?
finlep [7]

The study of the relationship between structures and functions is at the very heart of biology. This relationship is expressed in living beings by the adaptation of the first to the second and poses a series of absolutely fundamental problems, such as the relationship between causality and finality, analogy and homology, structural improvement and evolutionary level, etc.

For example, the structure of the hand is related to its function, thanks to the fingers and the thumb it is easy to wear and store objects.

The zigzag structure of the intestine is related to its absorption function, as this makes it possible to increase the contact surface between the alimentary bolus and the intestinal wall, and thus to increase the absorption.

If blood pressure is too high what should homeostatic regulation do
Anastasy [175]
Homeostasis is one way our bodies maintain its parameters within the normal range of values. We can say that it is key to life. When homeostasis fail, it can lead to diseases like hypertension and diabetes. In homeostasis, there will be stabilization of blood pressure as well as maintenance of its steady resting state. Take this scenario as an example, if a person exercises, there will be an increase of the heart rate, which will also result to higher blood pressure. The process of homeostasis will then accommodate the body through different mechanisms to make the decrease of the heart rate possible and at the same time reduce the high blood pressure. It is through homeostatis by which the normal body functions are maintaned in order to sustain life.
