Answer:

Option B

Explanation:

Question -

You just came back from class in which the topic was egocentrism in the preoperational stage. You have a 4-year-old and thought that you would see if what you learned was accurate. You are sitting directly across from her and ask her to look at the front and back cover of her favorite book. After she did this you asked her to describe "the part of the book I am looking at." What does she tell you?

a) how many pages there are in the book

b) what she sees

c) what you see

d) what the story is about

Solution

As per Piaget's theory of cognitive development, when a child is at the preoperational stage he/she is able to think only at symbolic level and cannot use his/her cognitive thinking.  

He/she is unable to derive senses or meaning associated with symbols and also his/her communication is egocentric which means they cannot think from the perspective of other people.  

Hence, option B is correct

Which cell is most important for the defense against parasitic organisms ?
Murljashka [212]

I'd say, ina general way, that the most imporant cells in defense against parasitic organisms are definitely white blood cels, the cells responsible for defeating antigens, pathogens and deseases.

Although these might be the most important ones in that specific task (defending against parasitic organisms), all the cells in the immune system, along with other non-cell things are important, since they all play a specific role indispensable in our immune system.
