Some aquatic organisms that live in cold environments similar to that of the crabs have multiple forms of certain enzymes that catalyze reactions at various temperatures. Explain how having multiple forms of the enzymes would contribute to the fitness of these organisms. Both adult and juvenile red king crabs can be found in ocean water of a different salinity and osmolarity than their body tissues are. Explain why it is important to the crabs that they can regulate the osmolarity of their tissues.

To maintain homeostasis.

Explanation:

It is important for the crabs that they can regulate the Osmoregulation of their tissues because they needs to maintain the homeostasis of the organism. This osmoregulation also maintains the concentration of water content and solutes in the body of crabs. So we can say that for maintaining balance in the body osmoregulation is very important for crab's tissues .

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
