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.

Eukaryotes have their DNA inside a nucleus while Prokaryotes just have it floating inside themselves
Carbon is a reactant in the process of photosynthesis but a product in the process of cellular respiration.
<h3>What is carbon cycle?</h3>
Carbon cycle is the physical cycle of carbon through the Earth’s biosphere, geosphere, hydrosphere and atmosphere.
It is the series of processes by which carbon compounds are interconverted in the environment, that includes such processes as
- photosynthesis
- decomposition
- respiration
- carbonification
Carbon cycle involves the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.
Therefore, carbon is present in the atmosphere as a reactant during photosynthesis and as a product during cellular respiration.
