Answer:
There are many receptors for thyroxine on different target cells (tissues), so its effect can be huge
Explanation:
Target cell for a certain hormone is a cell that have hormone receptor specific for that hormone. There are two main types of receptors on target cell:
- cell membrane receptors (also called trans membrane receptors)-usually for peptide hormones, such as insulin
- intracellular receptors (also called nuclear receptors)-usually for steroid hormones, such as testosterone.
Hormone binding to the receptor leads to the signal cascade within the cell, which results in cell response.
Receptors for thyroid hormones are nuclear receptors.
The appropriate answer is C. ANCESTRAL FINCH. The study of these birds on the Galapagos island led to Darwin proposing his theory of natural selection. Darwin collect and preserved samples of the finches he observed while on his travels.
He did not observe anything unique about the birds until after he returned home. He focused on the differences in the beaks of the birds. It is then that he started to work on his revolutionary theory.
I think that the answer is global warming
