Ans.
Unicellular organisms are those organisms that are made up of a single cell, while multicellular organisms are made of up more than one cell. During 17th century, a scientist could distinguish between an unicellular and a multicellular organism by using simple microscope, developed by Antony Van Leeuwenhoek. In the mid-20th century and 21st Century, a scientist could make distinction between unicellular and multicellular organisms, by using advance microscopy techniques, such as electron microscopy and electron microscopy.
It would be Li and F because Li has 3 electrons which means it has an unstable outer shell as it would have 1 electron in the outer shell, however, F has 9 electrons and it needs 1 more electron in its outer shell in order to become stable so it will be shared with Li

Commensalism
Explanation:
In the rainforest, small plants called bromeliads lives on the branches of tall trees which allows them to receive sunlight for photosynthesis. They are commensals in this regard.
The interaction between the plant and the bromeliads is a commensalism.
Commensalism is a feeding relationship in which one organism derives benefit from the other without causing it harm.
- It is a positive - zero relationship in which one organism benefit and the other is not harmed.
- In mutualism, both organism derives benefits from one another.
- For parasitism, one organism derives benefit and causes harm to the other.
