Drugs or chemicals can: a. all of these choices are correct. b. facilitate the transmission of information from one neuron to another. c. inhibit the transmission of information from neuron to another. d. be used to cure a whole variety of clinical disorders by playing a role at the synaptic level.

A. All of these choices are correct.

Explanation:

In pharmacology , drugs play different roles from simple to complex.

as is the above mentioned question drugs can facilitate the transmission of information from one neuron to another so option B is correct.

While the drugs / chemicals can  inhibit the transmission of information from neuron to another so option C is also correct.

And the drugs can also be used to cure a whole variety of clinical disorders by playing a role at the synaptic level.

Hence option A All of these choices are correct is the right answer.

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.

the correct answer in apex is tissue development, i know because i just had this question
