It can be caused by the humid air or surrounding.
Humid air makes the stones absorb water and therfore makes it soft.
<span>According to a source the answer is B. They save energy and metabolites and help the organisms to respond to the environmental changes.
</span>A genotype is a set of genes in the human DNA responsible for different traits. It represents your complete identity that you will inherit from your parents and ancestors.
<span>On the other hand, a phenotype is how that trait expresses physically, a characteristic, a visible description of your physical features, including height, eye color, overall health, history of diseases, the ability to gain or lose weight fast, what type of food you like, what you enjoy and what you hate. </span>
Answer:
The pressure varies linearly with depth if the fluid is incompressible. For a horizontal surface, such as the bottom of a liquid-filled tank Fig. 1, [2], the magnitude of the resultant force is simply FR = pA where p is the uniform pressure on the bottom and A is the area of the bottom.

The deuterostome group's gene arrangement in the mitochondrial genome of <em>Xenoturbella bocki </em>is remarkably close to that of the chordates and hemichordates and hence to the ancestor deuterostome gene order. Inversion and breakpoint studies particularly point to a similarity to the hemichordates.
Previous morphological investigations imply that Xenoturbella could be classified as a bivalve mollusc, a basal bilaterian, a turbellarian flatworm, a sister group to the echinoderms(nonvertebrate), or a hemichordate. Recent genetic analyses that focus mostly on nuclear genes appear to favour the Ambulacraria (echinoderms + hemichordates). In contrast, a basal deuterostome location is supported by mitochondrial sequences.
