In the animal kingdom there is a lot of diversity...
First: There are <em>carnivores, herbivores and omnivores. </em>Carnivores eat strictly meat. Herbivores eat vegetation and plants. Omnivores are like you and I, we eat anything, meat, vegetation, etc.
Second: There are several main classes, the Land Animals, the Sea Animals and the Air Animals. Land: Anything such as horses, deer, cats, camels, lizards, bears, foxes, moles, mice, dogs, tigers, lions, zebra, cows, goats, pigs, ocelots, monkeys, etc. Sea: Sharks, fish, octopus, dolphins, whales, sea horses, sea urchins, eels, sturgeon, angel fish, etc. Air: Hawks, eagles, vultures, toucans, parrots, crows, ravens, blackbirds, blue jays, chickadees, woodpeckers, swallows, etc.
Third: There are classes such as feathered (birds), scaled (reptiles), furred and such. Feathered: Chickens, eagles, toucans, turkeys, grouse, ravens, crows, etc. Scaled: Lizards, snakes, sharks, fish, etc. Furred: (Domestic) Horses, cows, dogs, cats, monkeys, etc. (Non domestic) Lions, tigers, bears, deer, elk, moose, etc.
The cycle has no beginning and no end. Rocks deep within the Earth are right now becoming other types of rocks. Rocks at the surface are lying in place before they are next exposed to a process that will change them.
Explanation:
There is no beginning or end to the rock cycle, since all rocks on Earth can be influenced by the cycle and develop into new types.
The cessation of telomerase activity as we age limits the number of times a cell can replicate. current research on telomerases is particularly useful in the fight against cancer. This is because, Cancer cells employ a mechanism that activates telomerases, which leads to uncontrolled cellular division.
The body's stages of life are intimately correlated with telomerase activity. During the development of the embryo, the enzyme is active. High telomerase activity, which allows cells to divide endlessly, is a characteristic of cancer cells. In 85–95 percent of malignancies, telomerase is active (3,4).
