Answer:
The mutation is on chromosome/karyotype 8.
Answer:
The correct answer will be option - D.
Explanation:
Slime moulds are the fungus-like protists which bear a structure called sporangium which produces spores. The sporangium is produced in fungi as well due to which these protists are called fungus-like. Although both produce sporangium but they are not closely related, rather they are distantly related organisms.
The appearance of a sporangium in both indicates that they had faced the same conditions due to which they both showed the same adaptation by producing the same structures performing the same function. In evolutionary terms, this is an example of convergent evolution.
Thus, option D is the correct answer.
Answer:
the chromosome are found in the nucleus of a body cell in pair
The lac repressor protein is bound to the operator region of the lac operon when there is no lactose in the medium. When introduced in lactose, it binds to an allosteric site on the repressor causing its to change conformation and release from the operator. This allows the polymerase that is bound to the promoter region to proceed transcription of the lac operon genes (LacZ, Lac A, and Lac Y). Translation of these genes forms enzymes that enable the organism to break down lactose for energy.
