<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:
interbreeding occurs
Explanation:
The speciation is a process through which from one common ancestor, two or more different species occur. This can happen because of multiple different factors. One of the factors is that the populations should be isolated geographically. This leads to limited gene pool, and also no interaction with the rest of the population, while in meantime developing traits that are suitable for the particular environment. One of the easiest ways to see of two animals are belonging to different species is can they produce fertile offspring. If the answer is no, then that means that they have diverged enough to be considered as different species. One thing that doesn't contribute to speciation is the interbreeding, as it is a process that occurs within the population, and it is a common process through which the traits of the population are passed on to the next generation.
<span>Amino acids are considered as the building blocks of protein's, so amino acid rich food simply means protein rich food. There are 20 classifications for amino acids but nine of them are essential since our body can't make them. Usually in diet important amino acids are Lysine (C6H14N2O2), Leucine (C6H13NO2), Valine (C5H11NO2), Tryptophan (C11H12N2O2), Isoleucine (C6H13NO2) Phenylalanine (C9H11NO2) and Threonine
(C4H9NO3).</span>
Answer:
During interphase, a cell is metabolically active
Explanation:
Cell cycle is divided into two stages: interphase (lasts 3/4 of the cycle) and phase M (1/4 of the cycle).
Interphase is also divided into three stages:
Phase G1
Protein and RNA synthesis is done.
Phase S
DNa synthesis is done.
Phase G2
Protein synthesis continues and the cell grows to start the division.
