Answer:
The most important reason for learning about environmental systems is due to the fact that we should know what's going on in the world around us. If we were to travel to Asia, we should know the forests that lie there to pack appropriately. It's also important to just be aware of how the world works. It's also good to know what rock type you'll be walking on, so you can pack shoes accordingly. Overall, it's better to know the world around you than to live in ignorance.
Answer: It is approximately the membrane potential at which the electrochemical gradient for Na+ is zero.
Explanation:
The charge in plasma membrane occurs with diffusion and electric fields.
For example, if there are two solutions, let's assume solution X and Solution Y are separated by a porous barrier (to diffuse in equal proportions).
The fundamental principle of diffusion states that solution from a high concentration diffuses to a lower concentration.
For instance, if the X solution contains 40 sodium ions and 40 chloride ions, the Y solution only has 30 sodium and 30 chloride ions. Due to the diffusion, these two solutions will mix and reach a steady-state.
The like charges repel, and opposite charges attract.
Answer:
Change in an organism's environment forces the organism to adapt to fit the new environment, eventually causing it to evolve into a new species. ... Organisms become isolated as a result of environmental change. The cause of isolation can be gradual, like when mountains or deserts form, or continents split apart.
