Females reach sexual maturity at 3-4 years. They can mate all year round, but mating is generally more common between November and April. Gestation for cubs takes about 16 weeks and the cubs are dependent on their mothers for about 18 months after that. The mortality rate of tiger cubs is fairly high - approximately half do not survive to be more than two years old. A tigress may give birth to another litter within 5 months if the cubs of the previous litter are lost. Tigers usually have a litter with 2-4 cubs but they can have as many as 6 cubs in one litter.
On average tigers will live for 10 to 15 years out in the wild and 16 to 20 years in captivity, though there is one Australian tiger recorded as living to the ripe old age of 26. It is doubtful that tigers past the age of 20 would remain fertile.
Taken together, this suggests that a single tigress may breed from 10 to 24 cubs over her life.

How many premierships have tigers won in NRL?
The Wests Tigers have won once and the Balmain Tigers now defunct have won 11 times. As of 2010.
How many times does the parent cell divides in mitosis?
Once, and then the two daughter cells can grow and later divide.
Do you believe the cork that Hooke observed could produce new cells Explain.?
No because what he saw was non living cell walls were cells once lived im not sure if the cell walls could produce cells.
Do animal cells have mitosis more than once?
Depends on the cell. If the cell needs to replicate multiple times to produce more cells, then yes, it will. The cells will replicate until maximum capacity is reached.
How many times does a cell divide into a million cells?
Just once, after it divides into a million cells it will get bigger.
How many offspring do koalas produce?
Koalas produce a single offspring, just once a year. On rare occasions, they may produce twins.
How many offspring do koalas produce and how often?
Koalas produce a single offspring, once a year. On very rare occasions, they may produce twins.
What is the union of egg and sperm to produce new cells?
Once a sperm enters the egg, fertilisation of the egg begins.
How do the helper T cells first become part of the immune response to invasion by a virus?
T helper cells (CD4 T cells) serve to guide the development of adaptive (acquired) immune responses. Once they are activated and instructed by cells of the innate (natural) immune system, they "help" to activate cytotoxic (CD8) T cells and B cells (antibody producers). In the case of viruses T helper cells, once polarized, will produce signaling molecules (such as IL-2) that alert the CD8 T cells to the infection and will help activate B cells and will instruct them as to which flavor or antibody is best to produce. The CD4 T cells will also release other signaling proteins (such as Interferons) that help get rid of the virus.
Does cochlear hair cells produce neurotransmitters?
No, cochlear hair cells do not produce neurotransmitters. They convert sound vibrations into electrical signals that are then transmitted to the brain via the auditory nerve. Once these signals reach the brain, neurotransmitters are released to facilitate communication between neurons.
Are specialized white blood cells that produce antibodies coded to destroy specific antigens?
Yes, specialized white blood cells called B cells produce antibodies that can recognize and bind to specific antigens. Once bound, antibodies can mark the antigen for destruction by other immune cells or neutralize its harmful effects. This specific recognition and response help the immune system target and eliminate pathogens effectively.
How many times does a cell devides in mitosis?
It divides once, and becomes 2 cells.
