Answer:

In between the A bands is a light area where there are no thick myofilaments, only thin actin filaments. These are called the I Bands. The dark bands are the striations seen with the light microscope. When a muscle contracts the light I bands disappear and the dark A bands move closer together.

How do biologists describe the order of the stages of the<br> cell cycle?
ololo11 [35]
The cell stays in the interphase stage the longest. The interphase stage includes the G1 phase which is the initial growth of the cell. Next is the S phase and in simple terms it’s just the replication of the DNA. Next is the G2 phase which is the continued phase of cell growth. After interphase is completed, the cell enters prophase, then metaphase, then anaphase, then telophase, and finally cytokinesis.

joja [24]

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
