The statement 'cell death normally does not occur unless there has been an injury to the cell' is false.
A cell can be described as the basic building block of life. All living organisms are known to be made of cells.
There are various reasons that a cell might die. A cell might die when its function is over. A cell might also die for the formation of other structures in the body. For example, the formation of an outer layer of the skin requires dead cells. A cell might kill itself if it has no use or finds that it has been invaded by an antigen.
Hence, the statement that cell death occurs only due to injury is false as cell death can occur due to various other reasons.

Explanation:
Iodine is needed by animals because the body's metabolic rate is controlled by the action of an iodine hormone, called thyroxine, which is secreted by the thyroid gland in the neck.
If the animal fails to supply enough iodine through food to be able to make a normal amount of this compound, then the thyroid gland enlarges or expands trying to create enough, resulting in a common type of goiter.
They help with storing "food" in fruits and foods to make them edible for us people.
