<h2>Answer:</h2>

Statement for Lactobacillus:

<u>Bacteria and humans are in mutualism.</u>

Statement for S. Typhi:

<u>Bacteria and humans are in parasitism.</u>

<h3>Explanation:</h3>
  • <em>Mutualism:</em> A symbiotic relationship between two species when both get benefits from each other without harming each other.
  • Hence Lactobacillus and humans both are benefited by each other. So its a mutualism.
  • <em>Parasitism</em>: A relationship where one species get the benefit and others get harm.
  • Here S.typhi lives in human and harms humans by infecting him/her.
  • So its a parasitism.

cupoosta [38]

Answer:

-S-phase

-Late telophase

Explanation:

The cell cycle is divided into two main phases: interphase and mitotic phase.

Interphase is phase characterized by the the cell growth and DNA copy (replication). During this phase, the cell prepares for division (mitotic phase).

Mitotic phase is subdivided into four phases: prophase, metaphase, anaphase and telophase. At the end of prophase, nuclear envelope breaks down and condensed chromosome (DNA structures) are released.

During the late telophase, nuclear envelope is reformed.
