Answer:
Unicellular organisms achieve locomotion using cilia and flagella. By creating currents in the surrounding environment, cilia and flagella can move the cell in one direction or another.

The type of reaction that is Mg +S→ MgS is a synthesis reaction
<u><em>Explanation</em></u>
Synthesis reaction as refers to as direct combination is a reaction in which two or more chemical species combine to form more complex product.
The reaction of Mg +S → MgS is a synthesis reaction because;
Mg combine with S to form a more complex product MgS
Answer: The order from weakest to strongest is:

Explanation:
Dispersion force is the weakest intermolecular force. It is a temporary attractive force that come into action when the electrons in two neighboring atoms are at the positions which results in formation of temporary dipoles.
Dipole interaction is an attractive interaction between the positive end and negative end of the polar molecule.
Hydrogen bond is a weak bond between two adjacent molecules due to an electrostatic attraction between a hydrogen atom in a molecule with an electronegative atom of an adjacent molecule.
Single covalent bond is more stronger bond than the the interaction stated above because there is sharing of an electron between two atoms.
Ionic bond is the strongest bonds in which complete transfer of electrons is present. Due to high electronegativity difference between the bonded atoms there is a high electrostatic interaction between the oppositely charged ions which makes ionic bond strongest from all the other types of the bonds.
So, the order is:
