Answer:
The answer is the Parietal Lobe.
Explanation:
Note that, Parietal lobe is part of the cerebral cortex, which further divided into three, namely,
1.The post central gyrus which receives sensory input.
2. The Superior Parietal lobe which doesn't involve in sensory processes.
3. The Inferior Parietal lobe which is the integration of multiple sensory signals
<span>Myelination enhances the speed of action potential propagation.
The difference between myelinated and unmyelinated axons are in the propagation of action potential. In unmyelinated axons, the action potential travels continuously through the axons. On the other hand, among the myelinated nerve fibres, transmembrane currents can only occur at the nodes of Ranvier where the axonal membrane is exposed, so the excitation of the axonal membrane jumps from node to node. This propagation is called saltatory conduction and this movement of depolarization wave is much faster than in unmyelinated fibres.</span>
Answer:
A golden retriever.
Explanation:
Prototype may be defined as the member among the group that is characterized as more central than the other member of the group. Prototype can be used in the taxonomy as well as in the evolutionary history as well.
The prototype is the main representative member of the group. The golden retriever dog is the most common member among all the members listed in the question. Hence, the golden retriever (dog) is considered as the prototype.
Thus, the correct answer is option (e).
<h2>Anaphase </h2>
Explanation:
Anaphase includes two major events:
- Separation of sister chromatids-is due to the destruction of cohesin protein which is catalysed by separase enzyme
Prior to anaphase securin binds to separase and inhibits its activity
The APC with specificity factor cdc 20 targets securin for polyubiquitination which then degraded by proteasome
The released separase becomes active and then breaks the cross link(bridge) between sister chromatids
- Movement of sister chromatids-occurs towards their respective poles due to shortening of kinetochore microtubules
