Answer:
continental drift
Explanation:
The most likely reason for this would be continental drift. It is believed that millions of years ago our world was one giant continent. This continent began breaking apart and drifting slowly more and more as millions of years passed by, ultimately creating the seven continents we know now. This would mean that Brazil and South Africa were most likely once the exact same location or the edge of where the continent broke apart. This would explain why the same rock was found in both locations.
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.
