Answer:
C. a pre-synaptic neuron involved in egg-laying
Explanation:
Serotonin (5-HT) is a neurotransmitter, i.e., a molecule that binds to specific receptors and thus transmits signals from one pre-synaptic neuron to another target cell. In humans, serotonin is involved in many physiological functions including sleep, mood, emotions, appetite, digestion, etc. Moreover, <em>Caenorhabditis elegans</em> is a model organism widely used in neuroscience research in order to understand neuromodulation at the level of individual neurons. In <em>C. elegans,</em> serotonin modifies behavior by regulating neuronal excitability and synaptic efficiency. Moreover, also in <em>C. elegans,</em> it has been shown that serotonin induces egg-laying and also provides a feedback regulatory mechanism by inhibiting the activity of the pre-synaptic neurons that release it. In consequence, in this case, it is expected that serotonin rescues the loss of function of serotonin receptors required for egg-laying by providing a regulatory feedback loop that contributes to serotonin adaptation.
<u>Answer</u>:
The proliferation of angiosperms is because they are Adaptable.
<u>Explanation</u>:
Angiosperms are those produces the gametes in the separate organs, those are present inside the flower. The embryo development and fertilisation takes place inside the anatomical structure, which provides a stable system of in sexual reproduction which will be sheltered from environmental fluctuation. For the example of co-evolution relationship between pollinator and flower characteristic will be considered. Most of them are mutualistic pollinator, having distinct features.
I think you meant element?
Then it is Krypton because it is in period 4 in group 18, the noble gases.
