Answer:
The region of retina devoid of photoreceptor cells (rod cells and cone cells)
Explanation:
The retina is the layer of the eyeball and is packed with rod cells and cone cells responsible for night and day vision respectively. The blind spot is the region in the retina where no rod cells and cone cells are present.
Absence of these photoreceptor cells ensures that no vision is formed in this part of the retina. However, the blind spot serves as the site from where the optic nerve passes through the retina and serves to transmit the impulse to the brain.
Answer: Expedition took place to extend the cave beyond its initial limit of exploration
Explanation:
Answer:
VDF= Vm- Veq.
Where VDF = Electrochemicall driving force
Vm=Membrane potential
Veq.=Equilibrium potential for the ion of interest
Ideally when VDF=0 at Electrochemical equilibrium, i.e. Vm=Veq, there is no net movement of ions across the membrane.
So, Answer is (D) This scenario is impossible.
This is because persistent organic pollutants accumulate in the body fat of living organisms and increase in concentration as they move up the food chain.
<h3>What is Persistent organic pollutants?</h3>
These are organic compounds that are stable and do not degrade easily. They are usually harmful and accumulate in the body fat of organisms.
They are also known to increase in concentration as they move up the food chain which is why predators have more of them.
