A postsynaptic neuron has three presynaptic inputs - from neurons X, Y, and Z. Stimulation of neuron X causes the postsynaptic n
xenn [34]

Answer:

Y is probably excitatory and Z is probably inhibitory

Explanation:

  • Two neurons communicate with each other generally by releasing neurotransmitters.
  • The neuron which releases the neurotransmitter is termed as presynaptic neuron and the neuron to which the neurotransmitter binds to exert its effects is called as postsynaptic neuron.
  • Based on the nature of the neurotransmitter released, the presynaptic neurons can either be inhibitory or excitatory in nature.
  • The change in the membrane potential of the postsynaptic neurons depends on the total sum of inputs coming from different pre synaptic neurons at a given time.
  • From the given situation, the stimulation by X alone is causing deploarization of 0.5 mV which shows that it is causing excitation, and since depolarization is increasing when X and Y are stimulaneously stimulated Y is also excitatory in nature. However the depolarisation is not occurring when X and Z are stimualted together and hence, Z is probably inhibitory in nature.

Which of the following show similarities between organelles and organs of the body?
sashaice [31]

Answer:

Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

What is the correct sentence?
lorasvet [3.4K]

Answer: The correct sequence in the expression of a trait is gene > protein > trait (Option B).

Explanation:

During gene transcription, a linear fragment of DNA referred to as a 'gene' is used as template to synthesize a complementary messenger RNA (mRNA) sequence.

Subsequently, this mRNA is then used as template to create a protein by a process called translation.

Moreover, phenotypic traits can be defined as all observable characteristics that an organism has.

The phenotypic traits are largely determined by the expression of either enzymatic or structural proteins, which interact to shape the phenotype of an organism.

In conclusion, the correct sequence in the expression of a trait is gene > protein > trait (Option B).
