Which of the following statements about brain development and early childhood is true? the brain of a 5 year old is 60 percent the size of an adult brain the overall size of the brain does not increase dramatically from ages 3-15 by the time a child is 3 years of age, the brain is 25 percent of it's adult size the development that occurs inside the brain ends at the onset of adolescence

The overall size of the brain does not increase dramatically from ages 3-15  

Explanation:

The functioning of the brain is still unknown to most citizens. For them, the organ is not considered an important factor for early childhood and its development is seen only as physical growth. The general population believes that brain structures are already ready at birth and that there is no change in the growth of children, this is incorrect. The brain spends a long period of time developing and establishing new brain structures, including changing size. However, total brain size does not increase dramatically between the ages of 3 and 15.

Option (B).

Explanation:

Natural selection may be defined as the process by which organisms adapt better in their environment, reproduce and produce their offsprings. Charles Darwin proposed the theory of natural selection.

According to Darwin, the natural selection may occur in the population if there is change in the natural environment of an organism. Large number of organisms may die due to the environment change but some members can survive and may adapt in that environment. Organism reproduce and pass down favorable traits onto their offspring.

Thus, the correct answer is option 2.
