Answer: E. all of the above.
Explanation: for human infants to grow and develop normally, the need for them to interact with people (family, friends and the public) cannot be over emphasized. Interaction with people goes a long way in the brain, physical and social development of infants.
Frequent interaction with people helps infants in their communication skills.
Cell<span> differentiation is how generic embryonic </span>cells become specialized cells<span>. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a </span>cell<span> functions

Green plants and certain other animals use a process called photosynthesis to convert light energy into chemical energy. Sunlight is the primary, non-recyclable, and easily accessible component of photosynthesis.
In the electromagnetic radiation that the Sun emits, sunlight is included. Water (H2O) and carbon dioxide (CO2) are ingested by plants during photosynthesis from the soil and atmosphere. In contrast to carbon dioxide, which is reduced within the plant cell and obtains electrons, water is oxidised within the cell of the plant. Due to this, carbon dioxide and water are converted into glucose and oxygen, respectively.
We can therefore conclude that green plants and some other animals convert light energy into chemical energy through a process known as photosynthesis. The most important, easily accessible, non-recyclable element in photosynthesis is sunlight.
