The recipe for these biscuits is closely guarded, but a quick look at the ingredients shows us that they're made with real shredded cheddar cheese, buttermilk, and a specialty garlic herb blend.

WebFrozen hydrated specimens Three typical examples of frozen hydrated samples are shown in Fig. 1: in (a) catalase crystals are embedded in a hexagonal ice layer with a maximum thickness of 300 nm, (b) lambda bacteriophages are shown embedded in a film of vitreous ice c. 100 nm thick and in (c) the water Ice Ih (hexagonal ice crystal) (pronounced: ice one h, also known as ice-phase-one) is the hexagonal crystal form of ordinary ice, or frozen water. Virtually all ice in the biosphere is ice Ih, with the exception only of a small amount of ice Ic that is occasionally present in the upper atmosphere. Ice Ih exhibits … See more The density of ice Ih is 0.917 g/cm which is less than that of liquid water. This is attributed to the presence of hydrogen bonds which causes atoms to become closer in the liquid phase. Because of this, ice Ih floats on … See more The hydrogen atoms in the crystal lattice lie very nearly along the hydrogen bonds, and in such a way that each water molecule is preserved. This means that each oxygen atom in the lattice has two hydrogens adjacent to it, at about 101 pm along the 275 pm length of … See more The accepted crystal structure of ordinary ice was first proposed by Linus Pauling in 1935.
