when crustaceans such as crabs are kept in seawater with a lower than normal PH, ATP-repuiring pumps that maintain ion gradients in the animals bodies significantly increase their activity in comparison with normal levels. Explain how the increased use of atp by these pumps will most likely affect the ability of the animals to carry out other metabolic reactions such as that catalyzed by PFK. Hemolymph is the fluid in the red king crabs body that surrounds its cells and is typically slightly hyper tonic to the seawater. explain how the crabs gained weight during this procedure

Subduction zones form when an oceanic plate collides with another oceanic plate or continental plate. the continental crust is lighter and less dense than oceanic crust. continental crust's density is approximately 2.7 grams per cubic centimeter. oceanic crust is thinner and the average density is about 3.3 cubic centimeters. when the two crustal plates converge the oceanic plate always bends and subducts beneath a continental plate. once the oceanic crust subjects, the rocks are subjected to changes in heat and pressure. because of this, we would expect to find rocks in the area of a subduction. a) clastic b) igneous c) metamorphic d) sedimentary
