The answer is pilus. This structure joins two bacteria of same species and allow exchange of genetic material in a process called horizontal gene transfer (conjugation). The plasmid of one of the bacteria (the mobile plasmid) is nicked once and the strand moves through the pillus to the other bacteria. It combines with the other plasmid or chromosome to for recombinant dna.
Answer:
Cancer cells are characterized by mutations associated with the uncontrolled growth of these tumor cells
Explanation:
Mutations in tumor suppressor genes are often associated with different types of cancers. On the other hand, mutations derived from the insertion of Transposable Elements may also activate cancer-related genes which are known as oncogenes
Answer:
Explanation:
Based on the information provided within the question it can be said that there are various reasons for the placement of this, most of the reasons include,
- To prevent or reduce sensitivity and discomfort of the prepared tooth & surrounding structures
- To protect the margins of the preparation
- To maintain the function & esthetics of the tooth
- To prevent shifting of adjacent or opposing teeth

The right answer is Exocytosis.
In a eukaryotic cell, exocytosis is a mechanism of material release by invagination of the cytoplasmic membrane. It consists of a spillage of the products of a vesicle outside the cell, by fusion of the plasma membrane with the membrane of this vesicle.
Its opposite (or reverse) is endocytosis. In the case of a vacuole, see the exocytosis vacuole.
