Because of egocentrism, a child is unable to analyze and view a situation from the perspective of other person. This is the second stage of Piaget's theory of cognitive development known as preoperational stage which generally starts at the age of 2 and last till the child is of age 7.
According to Piaget, an egocentric child (beng unable to think of someone’s else perspective) believes that the other person will also see/feel/hear the same as he/she does him/herself.
Hence, option B is correct
Answer:
Due to increasing the survival.
Explanation:
The natural selection causes a change in allele frequency leading to a change in the color of the frogs because the colour of the frog helps it in hiding from predators. The population of that frog specie increases which has the ability to hide from the predators in that environment while on the other hand, the population of frog decreases which can easily be seen by the predator due to its colour so this change in allele frequency will leads to natural selection.

Answer:
The gene for beta-galactosidase turns off.
Explanation:
The gene that codifies the beta-galactosidase enzyme is part of the <em>lac</em> operon, which also contains two other genes that produce enzymes involved in the metabolization of lactose.
Between glucose and lactose, the bacteria will preferentially use glucose as an energy source. On the other hand, lactose is a dimer, and thus a series of enzymes are needed to process lactose before its use as an energy source.
If there is no lactose present, the genes contained inside this operon are turned off (the operon is repressed).
