How do arachnids conserve water

Aquatic arthropods respire with gills. ... Arthropods excrete by means of malphigian tubules, projections of the digestive tract that help conserve water. Terrestrial forms excrete nitrogen as uric acid, as do birds. Their waste is nearly dry, a superb adaptation to life on land.

the cells uses some of the atoms of the glucose molecules to atp molecules. the atoms of the glucose molecules will then be converted into energy which will be eventually stored in atp. the energy produced which are stored in atp are coming from the glucose’s chemical bonds.
