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.
Answer:

Explanation:
Granite is a type of grainy (medium-coarse) igneous rock. These are formed from quartz, alkali feldspar and trace minerals along with plagioclase. Rocks like quartz, form a crystal from magma or as a precipitate near hydrothermal vents.
A type of intrusive igneous rock, granite is formed from its constituents when it molten rock cooled. Larger mineral crystals are associated with slower cooling over time.
