It is charged because the number of electrons do not equal the number of protons in the atom or molecule. ... When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION.
Plant cells are not necessarily square, but they due tend to have distinct edges and be kind of rectangular. This structure is caused by the cell wall which is very rigid and therefore forces the cell to have a more defined shape. However, animal cells do not have a cell wall but only the plasma membrane. Which is is why it's round.
Answer:
Matter have two essential types of properties, those are physical properties and chemical properties.
Explanation:
Answer:
<em>Structural failure is initiated when a material is stressed beyond its strength limit, causing fracture or excessive deformations; one limit state that must be accounted for in structural design is ultimate failure strength.</em><em><u>Compressive, tensile, bending and buckling are the basic types of structural failure for construction elements. These are caused due to faults in design and construction</u></em>
