Which of the following statements about receptor potentials is FALSE?a. Odor molecules can act as stimuli. b.The receptor potential is carried by neuroglia. c.The receptor proteins respond to stimuli. d.They can trigger an action potential.

The correct answer is option b. "The receptor potential is carried by neuroglia".

Explanation:

Neuroglia is a term used to describe a class of cells which main function is to support the neurons. The term neuroglia include astrocytes, ependymal cells and oligodendrocyte. It is false to affirm that the receptor potential is carried by neuroglia, the receptor potential is carried out by the neurons.

b.The receptor potential is carried by neuroglia.

When   receptor cells   responded to a stimulus of touch, pressure,lights, (which is up to the threshold levels)  they produce an action potential.Such potential generated by the cell is called Receptor potential.

They are transducers cells  which  converts different forms of stimulus to electrical signals in the neurons.

The reversal of charges  due to stimuli of touch, smell, light or chemical substances cause depolarization  and   generates action potential. If this is up to the threshold levels, action potential is propagated along the sensory neuron to the  cerebral cortex of the brain.

Neuroiglia   are cells of the CNS and PNS. that provide support and protection to the neurons. They do not transmit electrical signals as action potential. The transmission of action potential is done by the sensory neurons.

explanation:

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
