Answer:
The human brain undergoes rapid growth from birth to age 2. During this period, it approximately triples in size, with most of the development happening in the first year of life. This growth is primarily due to the formation of new neural connections and the myelination of existing ones, which is essential for cognitive and motor skill development in early childhood.
Answer:
The disintegration of rock by chemical weathering into small grains is not considered as reproduction.
Explanation:
Reproduction may be defined as the biological process of production of an offspring. Two main type of reproduction is asexual reproduction and sexual reproduction.
The breakdown of rock into small particles is not considered reproduction because this is a chemical process not a biological process. The living cells are not involved in the chemical weathering of rock. The small grains will not reproduce and divide to form the next generation offspring.
Thus, the process of chemical weathering is not considered as reproduction process.
