Answer:
The correct answer will be option- adhere to cell surfaces.
Explanation:
The bacterial fimbriae are the cellular appendages which help the bacteria to attach to a substratum. This attachment property of the fimbriae is due to the presence of a protein called adhesins.
The fimbriae are also known as the attachment pilus of the bacteria which are thinner than a flagellum. The bacteria posses many fimbriae to adhere to the surface like to receptors, another bacteria or any other substratum.
Thus, option- adhere to cell surfaces is the correct answer.

Brain can create new connection between neurons.
I think the nurse should include, the hand and elbow of the affected arm will be elevated above the shoulder. Mastectomy is the medical term for the surgical removal of one or both breasts, partially or completely, normally carried out to treat breast cancer. It is also usually used for women at high risk who have prophylactic mastectomy.
Answer:
Internal receptor: Internal receptors present on the cytoplasm, and also known as cytoplasmic or intracellular receptor. These Internal receptors respond to hydrophobic ligand molecules which can travel across the plasma membrane. These receptors can influence (directly) the gene expression means how much a specific protein is produced from a gene without having to pass the signal on the other receptor.
Cell-surface receptor: cell-surface receptor is present on the cell membrane is known as trans-membrane receptors. This trans-membrane receptor binds to external ligand molecules which cannot travel across the cell membrane. They are also called cell-specific proteins because they are specific to individual cell type. The cell-surface receptor has 3 main components:
1) External ligand-binding domain.
2) Hydrophobic membrane-spanning region.
3) Intracellular domain.
The mechanism of contraction in smooth muscle is different from skeletal muscle in that the site of calcium regulation varies. In addition, in an isotonic contraction the muscle alterations in length and moves the load and the the muscle cell membrane is named the sarcolemma.
