Answer: The correct answer for the fill in the blank is A) Found near coasts.
Chaparral biomes are found in small regions of almost every continent. This generally includes areas near the coast like the coastal areas of the Mediterranean. They have quite hot and dry cimatic conditions.
The different types of terrains in these biomes are slopes of mountains, rocky hills etc. The weather conditions change constantly in these biomes. Therefore, plants and animals found in these biomes adapt quickly to the changing environmental conditions.
The came too fast.
During the 20th century the canal water efforts to create major changes in South Florida landscape. The leeve-canal in Evergrade failed to improve the wetland habitat, a canal was constructed to drain and reclaim the wetlands.
The answer is false, liquid molecules continue to move even after the concentration is uniform.
Diffusion happens because there’s a concentration gradient between the dye and the water, therefore dye molecules moves to the water area. But note that this is only the net movement of the molecules, which means, even if more molecules are moving towards water, there are still some dye molecules that are moving in the opposite direction.
So, after the concentration is equal, the motion of the dye molecules does not stop, they still move in random directions, but there’s no net movement instead, as there’s no concentration gradient. Remember molecules are always moving in all directions , it just depends on whether there’s a net movement or not. If there’s no net movement, the amount of molecules moving to each and every direction is always equal.
When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.
This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.
The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.
