Answer:
A drug that blocks the effects of a neurotransmitter is known as antagonists. A drug that mimics or increase the effects is known as agonists.
Explanation:
An agonist is a chemical that binds to a receptor and activates the receptor to produce a biological response. Whereas an agonist causes an action, an antagonist blocks the action of the agonist. A receptor antagonist is a type of receptor ligand or drug that blocks or dampens a biological response by binding to and blocking a receptor rather than activating it like an agonist. They are sometimes called blockers; examples include alpha blockers, beta blockers, and calcium channel blockers..
Answer:
Collections of nerve cell bodies in the peripheral nervous system are called <u>ganglia.</u>
Explanation:
Ganglia are structures enclosed in a tissue sheath, which contains cell bodies of neurons. They also contain dendrites that make synaptic connections between neurons, transporting electrical impulses, connecting the brain with specific organs. They are part of the peripheral nervous and are responsible for connecting the peripheral nervous system with the central nervous system, both in an efferent sense (from the central nervous system to the sensory organs), and afferent (from the sensory organs to the central nervous system).
<h2>Bacterial chromosome
</h2>
The DNA of most bacteria is contained in a single circular molecule, called the bacterial chromosome. The chromosome, along with several proteins and RNA molecules, forms an irregularly shaped structure called the nucleoid. This sits in the cytoplasm of the bacterial cell
Answer:
Dessert and tundra
Explanation:
Theses two biomes get very little rain and because of this they have a less diversity of fauna and flora.
The differences are that a tundra is very dry and extremely cold and on the other hand a desert is very arid and hot and it can go as high as 54°C (130°F).
