|
Metamorphosis involves many changes in gene expression. How is it regulated?
|
|
Internal stimuli only-Hormones do all the signaling for expression.
|
|
|
External stimuli only-Temperature does all the signaling for expression.
|
|
|
Internal and external stimuli-Temperature, resource availability, hormones, and other internal chemicals cause regulation.
|
|
|
Neither internal nor external stimuli-The genes know what to do on their own.

Explanation:
Detailed explanation-1: -Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal’s body structure through cell growth and differentiation.
Detailed explanation-2: -Thyroid hormone (TH) is the most important hormone in frog metamorphosis, a developmental process which will not occur in the absence of TH but can be induced precociously by exogenous TH.
