Snezhnost [94]

Answer:

The correct answer is "strengths: inexpensive, easy to culture, short life cycle, large number of offspring; weaknesses: invertebrate model, some diseases such as immunological cannot be modelled, anatomical features are very different from humans"

Explanation:

The fruit fly <em>Drosophila melanogaster</em> is one of the most used animal model for genetic and biomedical studies. There are many advantages of using Drosophila as model, including that it is very inexpensive to handle, it is easy to culture, it has a short life cycle allowing to observe the changes in phenotype very quickly and its large number of offspring allows to include several repetitions per trait in a study. However, there are some weaknesses of using Drosophila to study human biology. First, obviously the fruit fly is very different from humans, it is an invertebrate and its anatomical features are very different, which makes impossible to model some disorders such as immunological diseases.

Neurotransmission is unidirectional insofar as chemical and electrical conduction is concerned within the individual neuron. Of
jasenka [17]

Answer: The correct option is C (Dendrites, Cell body, Axon, Axon terminals)

Explanation:

The transfer of information from neuron to neuron takes place through the release of chemical substances into the space between the axon and the dendrites. These chemicals are called neurotransmitters, and the process is called NEUROTRANSMISSION.

The order of neurotransmitter/receptor interaction that results in an electrical signal impulse and the release of another neurotransmitter for interaction in the synaptic cleft (signal conduction through a neuron) is from Dendrites--> Cell body--> Axon-->Axon terminals>

DENDRITES extends from the cell body of a neurone to receive messages at neuromuscular junction from other neurons. The CELL BODY directs all activities to the axon. The AXON is a long single fibre that transmits messages from the cell body and ends in terminals forming a synapse. Nerve impulses arrives at the axon terminal causing the release of neurotransmitters. The neurotransmitters binds to receptors at the dendrites of another neurons. The electrical signal impulses generated causes the release of neurotransmitters in another neuron.
