The synapse is typically located between the _____ of the first (sending) neuron and the _____ of the second (receiving) neuron.
uysha [10]

Answer:

axon; dendrite

Explanation:

A neuron has three main parts. These are axons, dendrites, and a cell body. Synapse is the site of communication between two neurons. The first neuron of a synapse is called the presynaptic neuron (sending neuron) while the second one is called the postsynaptic neuron (receiving). The axon of the presynaptic neuron and the dendrites of the postsynaptic neuron communicate with each other at the synapse as the axon of the first neuron delivers the nerve impulse away from the cell body.

Dendrites function as the receiving or input portions of a neuron. The plasma membranes of dendrites have numerous receptor sites for binding chemical messengers from the presynaptic neuron.

Anuta_ua [19.1K]

Explanation:

Metabolites are the different kinds of the substances which are essential to metabolism of the organism.

Metabolites produced by the plants can be categorized into the primary metabolites and the secondary metabolites.

The primary metabolites have important role in survival of plant and play an active role in the respiration and the photosynthesis.

On the other hand, the secondary metabolites are not involved in normal growth and the development of plant. Although absence of these type of metabolites can lead to impairment of survivability of plant in long run.

<u>Secondary metabolites are produced mostly by the plants for the defense purposes.</u> They include steroids, alkaloids, phenolics, essential oils, resins, tannins, lignins, flavonoids, etc.
