Typical Mortars. Projected Grenades The most commonly used projected grenade is the 40 millime-ter (40mm) grenade. This grenade is also among the mostcommonly found UXO items. The 40mm grenade is about thesame size and shape as a chicken egg, as shown in Figure 7.
A female cat is called a queen. Male cats, on the other hand, are called toms. Cats are generally associated with the female of the species. When you call a woman ``catty'', for example, what you are implying is that she is very unpleasant and usually has a lot of nasty things to say about others.
Some male calico or tortoiseshell cats may be chimeras, which result from the fusion in early development of two embryos with different color genotypes. Others are mosaics, in which the XXY condition arises after conception and the cat is a mixture of cells with different numbers of X chromosomes.
