Explanation:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
Answer:
Fusion doesn't produce radioactive waste products.
Explanation:
Fusion type of reaction does not produce any type of radioactive waste products, it produces helium, neutron and releases huge amount of energy while on the other hand, fission reaction causes the splitting of a single nucleus into two which produces gamma radiation and releases huge amount of energy so by seen the products we can say that fusion reaction doesn't produce radioactive waste products but the fission reaction can produce.

Glue adjacent cells together.
Explanation:
The middle lamella of plant is the outermost layer of the matured plants cell wall and it is made up of calcium and magnesium pectates. It is the layer that glue to adjacent cells wall together. The primary walls that are glued together is the cellulose layer that is shedd by a growing and dividing cells. The pectins In plants form a layer between the adjacent cells.
