Hydrogen bonding is a interaction between two hydrogen atoms that is very essential for life on Earth. It is notoriously seen between water molecules, and it occurs when there is a slight disbalance in electrical charge between two Hydrogen atoms, and Oxygen atom that comprise water. This slight imbalance makes the Oxygen slightly more electronegative, and the two hydrogen atoms slightly more electropostive. The reason why water when spilled forms globules for this exact reasoning. The slightly positive charged hydrogen feels an electrostatic attraction to the Oxygen atom thus forming a strong bond. An interesting fact that comes from this electrical disbalance is that when salt is added to water, water is able to conduct electricity because of this disbalance in charge it can seperate the sodium chloride lattices into ions.
Phoresy is the name of the symbiotic ecological relationship where one organism attach to the other (Option B).
<h3>What is Phoresy?</h3>
Phoresy is an ecological relationship where a given biological organism travels on the body of another organism.
The life forms in this type of ecological symbiotic relationship (phoresy) are not parasitic type.
In conclusion, phoresy is the name of the form of symbiotic ecological relationship above described.

Answer:
no they do not have hair, even tough it may look like they have hair its only pieces of skin.
Explanation:
Answer:
The unit cell's edge length is 
Explanation:
Number of atom in BCC unit cell = Z = 2
Density of barium metal= 
Edge length of cubic unit cell= a = ?
Atomic mass of Ba(M) = 137.33 g/mol
Formula used :
where,
= density
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
On substituting all the given values , we will get the value of 'a'.
The unit cell's edge length is
That is known as a tumor. Or cancer
