Explanation / Answer

Ans 25:- (E) Development.

Explaination:-  The process in which someone or something grows or changes and becomes more advanced is called as development.

Ans 26:- (E) number of hydrogen ions has increased.

Explaination:- With the increase of hydrogen ions in the solution the pH decreases and thus the acidity of a solution increases hence the correct statement is option E.

Ans 27:- (A) Histology.

Explaination:- Histology is the study of anatomy of cells, the cells are maintained in a vials at a very low temperature in liquid nitogen and hence kept in a frozen state for further studies hence the statement A is correct option.

Ans 28:- (A) Maxilla.

Ans 29:- (A) GTACAG

Explaination:- As per Chargaff's rule A pairs with T and G pairs with C i.e A--T and G--C pairing occurs. hence the correct statement is A.
