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.
<h2>Symptoms of Achondroplasia</h2>
Explanation:
- Achondroplasia is caused about by a quality change (transformation) in the <em>FGFR3 gene</em>
- The <em>FGFR3 quality</em> makes a protein called fibroblast development factor <em>receptor 3 </em>that is engaged with changing over ligament to bone
- <em>FGFR3</em> is the main quality known to be related with <em>achondroplasia Achondroplasia</em> is acquired in an autosomal predominant example, which implies one duplicate of the adjusted quality in every cell is adequate to<em> cause the confusion</em>
- In the rest of the cases, individuals with <em>achondroplasia </em>have acquired an adjusted <em>FGFR3 quality</em> from a couple of <em>affected parents</em>
...The enzymes in the shrimp denature when exposed to the higher heat. Enzymes denature at high heat. That's what kills you when you're fever is too high, your enzymes denature, which means they are deformed/ become the wrong shape. Since the activation sites on enzymes are very sensitive to shape, they wouldn't work anymore. The cold doesn't denature enzymes however. They don't work as quickly but they still retain their shape.
