Answer:
The above statement is false.
Explanation:
<em>As we can infer from the question, Thymine is being replaced by Cytosine at position 3 of a genetic sequence. This means that only a single change is being made in the genetic sequence. This change will cause a faulty protein to be formed. The faulty protein will be associated with this genetic sequence. </em>
<em>Hence, not all of the changes existing between the cichlid and coelacanth/frog will be associated with this single base change.</em>
However, instead of replacement of C with T, if an addition or deletion of a base might have occurred, then the entire genetic sequence would have been altered causing many changes.
Bacteria would be an example of a prokaryotic cell.

Answer:
The correct option is A) the hypothalamus
Explanation:
The hypothalamus is a part of the diencephalon located below the thalamus and formed by several nuclei of neurons with their associated nerve fibers, many of them neurosecretory nature, that is, to the hypothalamus, afferent and efferent pathways arrive and depart respectively, which connect it with different regions of the brain and outside it, receives signals from internal sensory receptors and, in response, sends orders through pathways in which very few synapses intervene to quickly generate regulatory responses, for this reason, the hypothalamus is considered the center of neuroendocrine, autonomous and homeostatic regulation, which acts as an integrating center coordinating environmental messages, rhythms, endogenous development patterns, emotions and body signals, to finally produce, in an integrated way, early autonomous responses and relatively late endocrine responses.
