d. wave shock
Explanation:
An adaptation can be defined as a phenotypic trait that makes an organism and/or species better suited to its environment, thereby this organism/species will have more chances to survive and reproduce in such conditions. Rock-dwelling aquatic animals have different ecological, morphological and behavioral adaptations to survive in this type of environment. In this regard, it is well-known that these organisms show dorsally flattened bodies, since it is one fundamental morphological adaptation which helps them to dissipate the force of the waves.
Any alloy of iron mixed with a small amount of carbon to increase its strength or malleability is called Steel.
<h3>Why we use alloy ?</h3>
The most common reason for alloying is to increase the strength of a metal. This requires that barriers to slip be distributed uniformly throughout the crystalline grains. On the finest scale, this is done by dissolving alloying agents in the metal matrix (a procedure known as solid solution hardening).
It increases tensile strength also. Hardness, hardenability and resistance to wear. It decreases tendency toward scaling and distortion. It increases the rate of carbon-penetration in carburizing.
<h3>How to make Alloy? </h3>
Alloys are made by mixing two or more elements, at least one of which is a metal. This is usually called the primary metal or the base metal, and the name of this metal may also be the name of the alloy.
