<h2>d) option is correct </h2>
Explanation:
The stringent response occurs in response to low energy store
For example when there is low level of lactose it means energy level is low so there will be no transcription of genes and hence transportation and catabolism of lactose will be inhibited
When E coli is grown in mixture of both glucose and lactose, at high glucose concentration the growth rate is maximum and lactose catabolism is repressed, this called as catabolite repression and it is due to level of cAMP
The correct option is D
Neurotransmitters are released from axon terminals via exocytosis.
A neurotransmitter is stored inside synaptic vesicles which is a small sac-like structure. It is released into the synaptic cleft from axon terminals when a cell membrane fuses with vesicles. This process is termed exocytosis with the capability to release neurotransmitters in less than a millisecond.
In neurons of the nervous system, synaptic vesicle exocytosis occurs. Nerve cells communicate by electrical or chemical signals called neurotransmitters which are passed from one neuron to the next one. This transmission of neurotransmitters occurs by exocytosis.
The fundamental biological events of neurotransmission are dependent on neuronal communication and brain function including exocytosis of presynaptic vesicles which is for the release of neurotransmitters and the subsequent endocytosis.

Answer is: <span>Using jargon, or overly complex terms, can contribute to semantic noise.
There are four forms of communication noise: </span>psychological<span> noise, physical noise, </span>physiological<span> and </span>semantic<span> noise.
</span><span>Semantic noise occurs when</span> sender of the message uses a word or a phrase (complex terms) that we don't know the meaning of.
All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.
