Alright, so in the given question here it says that you are genetically engineering a superhuman and are currently designing your creation's endocrine system.
00:09
So, you realize that you will need your superhuman to undergo massive change in body shape and capability that is metamorphosis when their superpowers activate within them.
00:19
So, you splice frog genes into your superhuman to do this.
00:22
So, when exposed to a massively stressful stimulus, they now undergo metamorphosis to their superhuman form.
00:28
So, what is the best explanation for how this occurs? alright, so here the best explanation for the given, for the given how the metamorphosis occurs in superhumans will be that, will be the last option that is the option fifth here that is because the frog genes, the thyroid axis can be readily activated with the same signals as those involved in the stress axis that is corticotropin releasing hormones from the hypothalamus stimulates thyrotropin, right, releases, released from the pituitary.
01:04
So, the tsh then stimulates the thyroid gland to produce and release thyroid hormones.
01:09
Now, deoninase type 2 activate, activate the t4 thyroid hormone and t3 in the peripheral target cells.
01:17
So, this spike of thyroid hormones initiates the reactions of metamorphosis by regulating the transcription of genes responsive to t3 bound to the thyroid hormone receptor, right.
01:28
Now, the frog genes which are introduced into the superhuman, it allows the thyroid axis to be readily activated by the same signals as those involved in the stress axis, right.
01:39
So, the corticotropin releasing hormone, so it is released from the hypothalamus in when a massively stressful stimulus is encounter.
01:53
The thyrotropin that is tsh, the release of crh, the release of crh, it stimulates the release of thyrotropin from the pituitary gland...
