Explanation:
Alcionaceans (Alcyonacea) is an order of corals that belongs to the subclass Octocorallia, of the Anthozoa class. <em>Soft corals</em> are commonly called, since they do not produce skeletons of calcium carbonate, so they do not contribute to the construction of the reefs, although they inhabit them.
The so-called soft corals and leather or leather corals, mostly meaty in appearance, have microscopic crystals of calcite in their tissues called spicules, whose function is to give consistency to the animal's tissue, in the absence of a skeleton. The shape and distribution of the spicules are the main characteristics used in the identification of genera and species of octocorals.
In addition to soft corals, this order includes gorgonians, which replace the skeleton of hard corals, Scleractinia order, by semi-rigid structures composed of calcite and / or a substance they generate called gorgonin.

Explanation:
These adaptive changes help in ways best seen between desert mice and those who live in darker habitats. While desert mice often developed extremely light colored coats to blend best with the environment, mice who live in forest's or valleys often have darker coats to blend with foliage and trees. These coats that help camouflage with the environment protect mice in the open from being snatched by say a eagle or bird of prey. And mice who blend equally with foliage are protected more from ground predators like other small foxes or rodents

The statement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.
<h3>What are homologous chromosomes?</h3>
Homologous chromosomes are set of chromosomes that possess similar but non-identical genes.
Homologous chromosomes are from each parent of an organism i.e. male and female parent.
The homologous chromosomes is responsible for the diploid state of an organism, however, it becomes separated during the anaphase 1 stage of meiosis.
Therefore, the satement that is true about homologous chromosomes of a pair is that homologous pair have the same genes at the same location (loci), but will possibly have different alleles.
