Answer
The function of the nucleus is 'To control the activities of the cell'.(b) 【Explanation】: The layer of cells lining the stomach is referred to as a 'tissue', specifically it's known as the epithelial tissue which is designed to absorb, secret, and protect the underlying structures. The 'stomach' is classified as an 'organ', it is a component of the human digestive system with a distinct structure delivering a specific task related to digestion.'Mouth, stomach, intestines, liver, and pancreas' in unison comprise an 'organ system', specifically, they form the digestive system, responsible for converting the food we intake into energy for the body and excreting the resultant waste. 【Answer】: - Layer of cells lining the stomach → A tissue- Stomach → An organ- Mouth, stomach, intestines, liver and pancreas → An organ system
Explanation
The function of the nucleus in a cell is to govern the cell's activities. However, it does not control the movement of substances into and out of the cell, as this function falls under the purview of the cell membrane. The nucleus is not responsible for releasing energy in respiration either because this process happens within the mitochondria.
