<em>Hardness is a measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied</em> <em>Macroscopic hardness is generally characterized by</em> <em>strong intermolecular bonds</em>, <em>but the behavior of solid materials under force is complex; therefore,</em> <em>there are different measurements of hardness</em>: <em>scratch hardness, indentation hardness, and rebound hardness. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and viscosity. Common examples of hard matter are ceramics, concrete, certain metals, and super hard materials, which can be contrasted with soft matter.</em>
 
        
             
        
        
        
Answer:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
-  sensory systems-detects ratios of glycolytic intermediates,
- global regulators-control the expression of genes that encode for enzymes.

<u>Answer:</u>
<em>Polymers of amino acids can be both fibrous as well as globular protein. Hemoglobin is a globular but the collagen is the fibrous protein both being the amino acids.</em>
<u>Explanation:</u>
- <em>Soluble in water: </em>globular protein is soluble in water.
- <em>intermediate filaments:</em> fibrous protein
- <em>Insoluble in water:</em> fibrous protein is insoluble in water.
- <em>function as structural proteins in the cell:</em> fibrous protein.
- <em>some function as enzymes: </em>globular protein.
- <em>structure is somewhat spherical;</em> globular protein.
- <em>structure is rod-like:</em> fibrous protein
