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.

What is the advantage of using STR for the identification of bodies from a mass disaster, such as the World Trade Center?
never [62]
The correct answer is C. Short tandem repeats are mostly different in unrelated peoples' DNA. Therefore, it is used to match the DNA of the people of the related family for identification of bodies, during a mass disaster like World Trade Centre. DNA from the nucleus is extracted in the process, and the STR containing regions are amplified and studied and can be matched with that of the relatives.

Question 10 of 10
mr Goodwill [35]

Answer:

bacteria

Explanation:

Nitrogen gas (N2) diffuses into the soil from the atmosphere, and species of bacteria convert this nitrogen to ammonium ions (NH4+), which can be used by plants. Legumes (such as clover and lupins) are often grown by farmers because they have nodules on their roots that contain nitrogen-fixing bacteria.
