Biology

daser333 [38]3 years ago
7 0

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.

When two species are forced to interact in a particular environment, how would
rjkz [21]

Answer:

Find the explanation below.

Explanation:

When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.

Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.

Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.

Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.
