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.
Calico cats are not always female. Male calico cats typically have a chromosomal aberration of two X chromosomes and one Y chromosome (XXY). Cats with this chromosomal configuration are usually sterile (not able to breed). This is similar to a condition in humans called Klinefelter's syndrome, or XXY Syndrome.
