D-Increasing porosity and increasing permeability lead to increased production in an aquifer
Option B:-primary succession
This is because of when the tectonic plates move it creates mountains. The valleys are at the bottom of these.
Lungs
Amphibians are known to be animals which can survive both on land and in water. They can walk on land and have limbs to swim. However, they do not have gills to breath but can only breath directly from air through lungs while bony fish have fins to swim in water and can breathe through there gills and filter oxygen from water.
Depolarization and Hyperpolarization occurs when ion channels open and close.
Explanation:
In some specific part of the membrane of neuron, the potential of the membrane becomes less positive it is that results in Hyperpolarization. Depolarization is in contrast with this, since the potential of the membrane will become less negative in this type. these two types occurs during the opening and closing of ion channels that are present in the membrane. This will result making the ions either entering the cell or exiting the cell.
hyperpolarization occurs when the channels opens and resulting in letting the ions that are positive to exit out of the cell. When the channel opening results in letting the positively charged ions to get into the cell, then depolarization occurs. The channel opening and closing highly depends on the binding nature of the molecules that are signalling.
