Answer:
The correct answer is: Attachment.
Explanation:
- Pilus are thread like structures which are present on the surface of the bacterial cell.
- They are mainly responsible for attaching the bacterial cells to a substrate, for obtaining food or to an eukaryotic cell for the purpose of infection.
- Pilus also mediate the process of conjugation in some bacterial cells.
- Conjugation is a process by which genetic material or plasmids are transferred from one bacteria to another through a channel formed in between the two bacteria by the help of the pilus.
- Pilus also helps the bacteria by preventing them from getting recognised by the immune cells in the host.
- A defective pilus will affect all the above processes, resulting in death of the bacteria.

Pretty sure it is decomposition, but it could be mineralization
Answer:
Permeable membranes allow anything to pass through.
Impermeable membranes have a poor permeable rate or nothing can pass through.
Semipermeable membranes select or allow only certain substances to pass through.
Explanation:
Permeable Membranes:
- Window screen - can pass water and air through 100%
- Mesh - can pass water and air through 100%
Impermeable Membranes:
- Clay - permeability rate is extremely low, and water cannot pass through
- Ziplock bag - nothing can come in or out
Semipermeable Membranes:
- Plant and Animal cell membranes (lipid bilayer) - only certain substances can pass through, like soluble vitamins
- Cell Organelle Membranes - only certain substances can pass through the mitochondria, for example
