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.
 
        
             
        
        
        
This statement is true.

It can sound like a snore with somehow long intervals between one gasp and another as it usually occurs at slow rates.</span>
        
             
        
        
        
Hi lovely,
Are you able to provide me with your answer choices?
        
             
        
        
        
Answer:
Its a substitution mutation because one of the specific base, G is replaced by A.
This is a Point Mutation because Point mutation brings changes in the structure of a gene because of the substitutions with another base pair. Like in this case, G is substituted by A. In case of frameshift mutations, there is a change in the number of nucleotides due to either insertions or deletions of the nucleotides, which is not in this case.
 
        
                    
             
        
        
        
Meiosis produces haploid cells rather than diploid cells because they need to make gametes (egg, and sperm cell) for reproduction.
