The correct Answer is:
To solve the question, we need to analyze each of the given tissues in mammals and determine whether they consist of a central 'medullary' region surrounded by a cortical region. ### Step-by-Step Solution: 1. **Understanding the Terms**: - **Medullary Region**: This refers to the inner part of an organ or tissue. - **Cortical Region**: This refers to the outer part of an organ or tissue. 2. **Analyzing Each Option**: - **Option 1: Ovary**: The ovary has a structure where the outer part is the cortex and the inner part is the medulla. Thus, it has both regions. - **Option 2: Adrenal Gland**: The adrenal gland is divided into the adrenal cortex (outer) and adrenal medulla (inner). Therefore, it also has both regions. - **Option 3: Liver**: The liver does not have a distinct medullary and cortical structure. It is primarily made up of hepatocytes and does not exhibit a clear division into cortex and medulla. - **Option 4: Kidney**: The kidney has a renal cortex (outer) and renal medulla (inner), fitting the description of having both regions. 3. **Identifying the Incorrect Entry**: - Based on the analysis, the liver is the only tissue listed that does not consist of a central medullary region surrounded by a cortical region. ### Conclusion: The wrong entry is **Option 3: Liver**.

The IUPAC name of [Co(H_2NCH_2CH_2NH_2)_2 (NO_2)NO_5 is bis(enthane-1,2-diamine) dinitrito-N-cobalt(III) nitrate.It follows the following rules that. (a)Cation is named first followed by anion. (b) Ligands are named in an alphabetical order before the name of the central atom/ion. ( c)Name of anionic ligands end in "o" (ex.chlorido) those of neutral (and if cation) ligands are the same except aqua for H_2O , ammine for NH_3 etc. (d)Prefixes mono,di,tri,etc.are used to indicate the number of individual ligand.When the name of the ligands include a numerical prefix, then terms bis, tris, tetrakis are used. (e)Oxidation state of the metal is indicated by Roman numeral in parenthesis. (f) For cationic and neutral complexes, the metal is named same as the element and for anionic complex, the name of metal ends with suffix-ate.For some metals, the Latin names are used in the complex anions , e.g., ferrate for Fe, argentate for silver etc. The IUPAC name of Fe_4[Fe(CN)_6]_3 is :
