Answer:
The subphylum Chelicerata (New Latin, from French chélicère, from Greek χηλή, khēlē "claw, chela" and κέρας, kéras "horn")[1] constitutes one of the major subdivisions of the phylum Arthropoda. It contains the sea spiders, arachnids (including scorpions, spiders, and potentially horseshoe crabs[2]), and several extinct lineages, such as the eurypterids.
Answer:
The correct answer is - solubility
Explanation:
Solubility is the nature of the material that is a chemical property of that specific solute ability to dissolved in a solvent. The ability of solute or material in a solvent or liquid is measured by the term of the maximum amount of that material dissolved in the liquid at equilibrium.
Sugar and water is a great example of solubility. When sugar is missed in the water it dissolved in water and disappear in the water here sugar is solute and water is solvent.
Thus, the correct answer is - solubility.
Answer:
the dissolved oxygen of the water decreases.
the fish need the oxygen for respiration, breathing through their gills.
Explanation:
The salinity decreasing doesn't affect the pickerel, because it's a freshwater fish. no salt needed.
more light penetrating the water just means that more aquatic weed or grasses would grow, giving the pickerel more area to spawn their eggs.
temperature increase in the summer has no affect on the fish, since the spawning happens in late winter.
