The given statement is True.
Visual Receptors: Rods and cones are the two types of cells present in the retal part of eye which works as a visual receptors which establishes a synaptic network involving neurons which connects the receptors to brain and help us in visualizing. However loss of neurons in the retina because of any kind of physical or biological damage permanently cuts the connection of receptors with brain and it cannot be replaced naturally.
Hearing receptors: Inside the ears there is a small structure known as cochlea which contains the organ of corti which further contains the hair cells [sensory cells] working as hearing receptors but research till date concludes that mammalian cochlear hair cells do not regenerate, either spontaneously or after damage.
Taste receptors: The small little bumbs present of our tongue are known as papillae whioch functions as taste receptors as they contain taste buds. Scientifically there taste buds die off and regenerate every few weeks.
Olfactory receptors: These receptors keep on replacing due to continuous differentiation of basal cells which develop and are capable of restablishing the connection with Central nervous system.

a gradual increase in the overall temperature of the earth's atmosphere because of the greenhouse effect caused by increased levels of pollutants.
Explanation:
Answer:
Active transport
Explanation:
Diffusion is when particles (like perfume) spread out everywhere from an area where there is a lot of it to where there is a little to none of it. Active transport is the opposite. A cell for example would use it's own energy to absorb nutrients when it already has quite a lot. Naturally diffusion would make the particles or nutrients go out of the cell because there is a lot of it inside the cell not outside, so active transport is used to absorb as much as the cell can from around it, even when it is full.
