Answer:
The connection between cancer cells stimulates uncontrolled proliferation and tumor growth
Explanation:
In the tumor, cancer cells are interconnected by different types of proteins, which may act as receptors or amplify oncogenic signals. For example, in breast cancer, it has been shown that oncogenic cells are often connected through E-cadherin proteins that mediate their adhesion, thereby stimulating the cell movement and invasion (characteristic of tumor metastasis). In this case, E-cadherin membrane proteins function by enhancing effector response in cancer cells. The nucleus acts as the control center of the cell that modulates the expression of tumor suppressor genes in order to inhibit tumor metastasis.

Answer:
The first part of the small intestine is called duodenum
Explanation:
The small intestine is a tightly folded tube which connects to the stomach on the top end and to the large intestine on the bottom end.
The small intestine consists of three parts:
- jejunum (absorbs sugars, amino acids, and fatty acids)
- ileum (absorbs remaining nutrients that did not get absorbed by the duodenum or jejunum)
Duodenum is responsible for completing the first phase of digestion. In this section of the intestine, food is mixed with enzymes and bile which help break down food.
