Some slime molds have some morphological similarities to fungi such as during times of stress they will develop into fruiting bo
gayaneshka [121]

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.

Which statement is not correct about the antibodies?
Marrrta [24]

Answer:

b. They are produced by memory B cells

Explanation:

The rapid cell division in activated B cells is followed by the differentiation of daughter cells into the plasma cells. The plasma cells are the precursor for antibodies and memory B cells. The antibodies kill the antigens while memory B cells are long-lived cells.  

Hence, antibodies are not produced by memory B cells but by plasma cells.
