B. Mitochondrion. Centriole is unique to animal cells and is used in cell division. Chloroplast and Cell wall are unique to plants cells, together with permanent vacuole. Both have mitochondrion, where energy is released through respiration.
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
<span>The reaction
that takes place in the stroma is collectively known as the Calvin Cycle. The
stroma is responsible for the 2nd stage of photosynthesis where ATP
and NADPH are used to capture and reduce carbon dioxide in the plant cell.</span>
<span>
It is a fluid-like organelle that surrounds the grana within the
chloroplast in plant cells. The stroma is also responsible for storing
chloroplast DNA and chloroplast ribosomes where molecular processes like
replication and transcription/translation of chloroplast proteins occur.</span>
