Answer:
b. help retain moisture in terrestrial habitats
Explanation:
Arthropods such as cockroach, centipedes, spiders, crab are the members of the largest phylum Arthropoda. These are animals with paired jointed legs and their body is covered with an exoskeleton made of chitin. They live in diversified habitat and exoskeleton helps to retain moisture in theterrestrial habitats.
Similarly mollusks such as sepia, snail are soft bodied animal whose body is covered with calcareous shell as a protection and to retain moisture while living on land.
The hydronium ion is an oxonium ion whose chemical formula is H3O + or H + (aq). It is found in the solid, gaseous or liquid state (protonation of a molecule of water).
The concentration of hydronium ion is directly linked to the pH of the tea (or any solution) by this equation.:
C° (hydronium) = 10^(-pH)
if the pH of the tea is 6 for example, than:
C° (hydronium) = 10^(-pH) = 10^(-6).
