No bulls don't have udders. A Bull is NOT a male cow! A bull is a male BOVINE. A cow is a female BOVINE.

An approximately 20-year-old Asian elephant cow weighs 3500 - 4500 kg on average, and measures around 2.6 metres at the back. An elephant bull weighs about 5000 - 6500 kg and measures around 3 metres at the back.\n\nAfrican elephants are larger and weigh more. An elephant cow measuring around 3 metres at the shoulders will weigh around 4000 - 5000 kg.\n\nAn African elephant bull, however, weighs around 6000 - 7000 kg and measures around 3.2 metres at the shoulders.

white. Black sucks heat in and makes you feel warmer.

They are exactly the same thing.  The only difference is that the human eye picks up a restricted range of wavelengths, and these are denoted "visible".\n\nVarious animals detect different wavelengths.  For them the visible/invisible divide is in a different place.\n\nAnd that is just part of the electromagnetic spectrum:

G'day Alli Oop94,\n\nThank you for your question.\n\nCows can see in things in front of them depending on where they are.\n\nCows are fisheyed with very different eyesight to humans.  There eyesight is poor and they need to lower their heads to see things on the ground. They will baulk at a shadow then lower their head to look at it further. Designers of cattle handling facilities are taking cows poor eyesight into consideration in design.\n\nThey are also colourblind so the legend that bulls get enraged by the colour red is a myth.\n\nI have attached sources for your reference.\n\nRegards

No. In fact I believe they are colourblind.\nBulls become enraged by the movement of the bullfighter's cape, not by its colour. The red colour is probably traditional because of the obvious connotations with blood.\nWearing red into a field containing a bull is no more dangerous that not doing so, but I wouldn't reccommend it.

Cows are descended from a European species called the Aurock.  The last Aurocks were killed by board German soldiers during WWI.  They just felt like shooting something.

<A bull is not a cow,they are cattle.In referring to domestic cattle a grown male is a bull, a grown female a cow, an infant a calf, and an animal between one and two years old a yearling. A female that has not given birth is a heifer; a castrated male is a steer.\nCattle is the name for the ruminant mammals of the genus Bos, and particularly those of the domesticated species, Bos taurus and B. indica. The term oxen, broadly used, refers also to closely related animals, such as the buffalo and the bison. Narrowly used, ox refers to a mature castrated male used for draft purposes.\n\nhousewife\n\nn : a wife who who manages a household while her husband earns the family income [syn: homemaker, lady of the house, woman of the house]\n\n\nSource: WordNet ® 2.0, © 2003 Princeton University

Bulls, like most animals are color blind.  \nHow do we know they are color blind?\nPeople and animals that can see in color have Rods and Cones in their eyes.  Cones see color, Rods see black and white.  Bulls don't have cones.\n\nNow if you'll turn to page 114 in your text book we will study the anatomy of frogs.  :-)

Cow's teeth are different from ours. On the top front, cows have a tough pad of skin instead of teeth. They have 8 incisors on the bottom front and 6 strong molars on the top and bottom of each side to grind their food. Cows have a total of 32 teeth.

Cows are "ruminants."  They have four stomachs and from the first one they can bring food back up later to chew it again.  They also have bacteria living in their gut that do part of the digestion for them.  Link below has a diagram and discussion.\n\nAloha
