Asynapse is a(n) question 27 options: a. chemical messenger that triggers muscle contractions. b. automatic response to sensory input. c. junction between a sending neuron and a receiving neuron. d. neural cable containing many axons.

The synapse is the junction present between two neurons.  

In a synapse, the electric impulses are transferred in the form of chemical molecule, which is also known as neurotransmitter. The synapse receives the signals from the sender neuron also known as presynaptic neuron to the receiver neuron, also called as postsynaptic neuron.

Hence, the correct answer is option c. junction between a sending neuron and a receiving neuron.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
