A dog's life cycle begins at puppyhood and spans an average of 12 years, although some dogs live considerably longer. The female dog generally become sexually mature by age one and can begin reproducing after that time if not spayed.
Kittens are heavily reliant on the mother for the first few weeks after they're born, and they cannot see or hear. They learn to walk at three weeks, and learn to respond to other cats. They have full coordination at seven weeks, and can become fully independent by 12 weeks. At 15 years of age, a ca
The life cycle of bacteria consists of four main phases: the lag phase, the exponential or log phase, the stationary phase and the death phase. Factors that trigger bacteria growth heavily rely on this life cycle. Bacteria multiply through a process known as binary fission.
The human life cycle begins at fertilization, then birth, and progresses through infancy, childhood, puberty, adulthood and aging, ending in death. Every stage is unique and encompasses changes in the human body.
A few hours after a cow is born, cows are usually removed from their mother, but they stay in their group until they reach the age of five. After the newborn calf is removed from its mother, it is fed milk replacer or actual milk until they are around 6 to 8 weeks old and begin to wean. Most calves
Domestic pigs grown for food are selected for the slaughterhouse after 5 months and therefore have a short life cycle. Feral hogs, however, typically live four to five years, with some lasting up to eight years.
The lifecycle of a spider begins with the laying and hatching of the eggs, moves to the development of the spiders and ends with the spider's reproduction, according to Brandeis University. Spiders are known for their web building, and each spider species uses its webs to catch prey, although many s
The life cycle of a frog begins first as an egg, then develops into a tadpole, a tadpole with legs, a froglet and then a full grown frog. For most species of frogs, the entire growth process takes around 12 to 16 weeks to complete.
The life cycle of a fly includes an egg, larva, pupa and adult. A fly completes its life cycle in 1 week to 2 months, depending on environmental conditions.
Seventy percent of snakes begin their lives growing inside of eggs, while the other 30 percent are born live. Some mothers leave, while others stay with their eggs until they hatch. This process is called brooding.
