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.

Horticulturalist’s best option is clone the desired tulip so there will be no genetic variations.
Explanation:
Cloning is a process by which replica of organism is made without having any genetically variations. It is done carefully to avoid any variations in the office bring that may be related to physical or genetic structure.
The process of cloning should be done under the supervision of expert to avoid any error which could lead to the variation in genetic structure. It is very necessary for the amateur horticulturalist who desires to have dual apps without any genetic variation to perform cloning.
