Answer:
DNA polymerase.
Explanation:
DNA replication may be defined as the process of formation of daughter DNA from the template DNA strand. The process of DNA synthesis occurs in the 5' to 3' direction.
The enzyme responsible for DNA replication is DNA dependent DNA polymerase or DNA polymerase. This enzyme moves in 5' to 3' direction. DNA pol III is main replicating enzyme in prokaryotes and DNA pol alpha initiates DNA replication in eukaryotes.
Thus, the correct answer is option (a).
Answer:
The importance of early childhood experiences for brain development. Children are born ready to learn, and have many skills to learn over many years. ... Exposure to stress and trauma can have long-term negative consequences for the child's brain, whereas talking, reading, and playing can stimulate brain growth.
Unused brain synapses disappear Research also shows that children born into cultures where early stimulation is considered important, develop earlier than Western children do," van der Meer says. She adds that the brains of young children are very malleable, and can therefore adapt to what is happening around them.
Stimulation in early childhood can alleviate adverse effects of poverty.
And early brain development has a lasting impact on a child’s ability to learn and succeed in school and life. The quality of a child’s experiences in the first few years of life – positive or negative – helps shape how their brain develops.

Answer:
The cell theory was given by Schwann and Schleiden. The fact that cells can be observed in plants, animals, fungi, protists, bacteria and archea comes from one of the postulates of cell theory- All living organisms are composed of one or more cells.
Explanation:
The cell theory initially contained three postulates:
- The cell is the basic unit of organization in all organisms.
- All living organisms contain one or more than one cell.
- All cells arise from cells which are already in existence.
The discovery of cell was made by Robert Hooke. Later after further observations, more points were added to the cell theory like
- The genetic component of the cell is DNA and is transferred within cells.
- The <em>chemical composition</em> of all the cells is similar.
- A flow of <em>energy</em> occurs within the cells.
