Answer:
The resting membrane potential is created and maintained due to the difference in the total charge or ions present outside and inside of the cell. The resting membrane potential depolarize if sodium come in and and potassium leaves the cell.
Explanation:
The resting membrane is maintained and created by the distribution of potassium and sodium ions. The membrane potential of a resting cell is -70mV (negative) because more sodium ions is present outside the cell than the potassium ions present inside the cell.
When the sodium ions enter inside the cell and potassium ions move outside the cell, the inside of the cell becomes more positive as compared to the outside and the membrane potential changes from -70 mV to +30 mV. The cells will depolarize due to the accumulation of sodium ions inside the cell.
The OECD found that the responsiveness of housing supply to demand in the UK was the weakest among developed countries, due in large part to green belt policies. The green belt concept was first introduced for London in 1938 before the 1947 Town and Country Planning Act enabled local authorities to designate the status themselves. The policy was introduced to contain urban sprawl following huge post-war housing developments, and expanded greatly between 1951 and 1964. Since 1979, the green belt has doubled to cover 13 per cent of land in England (while only 2.3 per cent is covered by buildings).
Answer:
rod photoreceptors
Explanation:
The retina of the eye has 2 types of sensory receptors or photoreceptors. They are the rod cells and the cone cells. The rod cells mostly found at the outer edge of the retina of the eye, which are numerous and more sensitive compared to the cone cells. The cone photoreceptors are found in the macula.
The rod photoreceptors are responsible for night vision mainly and function in dim light or less intense light, while the cone receptors are responsible for color sensitivity.
The rod photoreceptors are responsible for processing his ability to see objects in the darkness.
