How long can a lemming live 30 and how long can a rat live

Rats can live for 1-3 years. Mice live for 1-3 years, mature early, and usually start breeding a few months after birth. Rats are mammals, rodents, rodents, commonly known as "rats", the mode of reproduction is viviparous, is the fastest reproduction of mammals, strong survival ability of animals.

There are about 480 species of rodents in the world, and rat tracks can be seen both indoors and in the wild.

Mouse characteristics: Rats are small in size, and their body color is mainly gray and brown. The upper and lower jaws each have a pair of incisors, most of which are toothless.

Rats mature sexually early, generally starting to reproduce a few months after birth. It can reproduce several times a year, and each time it gives birth to about 10 litters. It is highly adaptable, widely distributed and has many species.

According to statistics, there are about 480 species of rodents in the world, and there are 34 species in China. Its main characteristics are that the body is tapered, there are no canines, there is a gap between the incisors and the premolars or molars, the incisors are developed, there are no tooth roots, lifelong growth, and common rodents are ground short; Act quickly; Plants are the staple food, and some are omnivorous; There are many types.

Hypothesis: Lemmings breed seven litters a year, 12 per litter, that is, 6 pairs, all of which are one male and one female, how many pairs can be bred in a year. Is the following algorithm correct?

1st batch breeding: 1st generation 1 pair breeding 6 pairs. 2nd batch breeding:

The 2nd generation breeds 6 pairs and 36 pairs. Plus the 2nd breeding of the 1st generation is 6 pairs, for a total of 42 pairs. 3rd batch breeding:

36 pairs in the 3rd generation, plus 6 pairs in the 2nd breeding of the 1st generation, 252 pairs in the subtotal 42 pairs, plus 6 pairs in the 3rd breeding of the 1st generation, and 36 pairs in the 2nd breeding of the 2nd generation. A total of 294 pairs. 4th batch breeding:

294 breeding pairs in the 4th generation bred 1764 pairs, plus 6 pairs in the 4th breeding of the 1st generation, and 36 pairs in the 3rd breeding of the 2nd generation. 1st breeding of the 3rd generation: 36 breeding pairs and 216 breeding pairs.

Generation 4 totals 2022 pairs. Breeding in the 5th batch: 12,132 breeding pairs in 2022, plus 6 breeding pairs in the 5th breeding of the 1st generation, 36 breeding pairs in the 4th breeding of the 2nd generation.

36 pairs of 36 pairs in the 3rd generation, breeding 216 pairs. The 4th generation, the 1st 216 pairs, 1296 pairs. A total of 13,686 pairs.

Breeding in the 6th batch: 13,686 breeding pairs and 82,116 breeding pairs. Plus 6 pairs were bred on the 6th of the 1st generation, and 36 pairs were bred on the 5th of the 2nd generation.

The 3rd generation of the 3rd 36 pairs bred 216 pairs. The fourth generation 2nd 216 pairs of dust reproduce 1296 pairs. The 5th generation, the 1st 1296 pairs, bred 7776 pairs.

A total of 91,446 pairs. 7th batch breeding: 91,446 breeding pairs 548676 pairs, plus 6 breeding pairs of the 7th 1st generation 1st pair of Lige Mill, 36 breeding pairs of 6 pairs in the 2nd generation.

The 3rd generation limb fights the 5th 36 pairs and breeds 216 pairs. The 4th generation of the 4th 216 pairs bred 1296 pairs. The 5th generation, the 3rd 1296 pairs, bred 7776 pairs.

The 6th generation 2nd 7776 pairs bred 466656 pairs. Total 604662 pairs.

Rats are a common lure-ambush mammal, and they are usually one of the small pets commonly found in pet stores. The lifespan of a rat is related to a variety of factors such as its breed, environment, and diet. Generally, the lifespan of rats is around 1-3 years.

Among them, some breeds of rats may live longer, such as Aung San rats, Dutch dwarf rats, and other breeds, which can live up to 3-4 years. However, wild rats rarely live for such a long time due to factors such as poor living environment and the presence of natural enemies.

When raising rats at home, we can extend their hallmark lifespan by providing them with a suitable environment and diet. This includes providing clean food and water, keeping their cages dry and clean, and taking them to the veterinarian regularly to check on their health.

Rats can live for about 3-5 days without eating or drinking.

Rats can live for more than 7 days without eating but drinking water, and can only survive for 3-5 days without eating or drinking. Rats are rodents of the mamma, rodents, and rodents of the family Ratidae. Due to its small size, slender bones, low energy consumption during exercise, and the very miscellaneous diet of the mouse in the spine posture, it basically eats everything it can eat, which provides a guarantee for its body to store energy.

Under normal circumstances, rats can eat a large amount of food, which promotes the storage of muscle and fat in the body, so they can ensure their basic life activities for a longer time when there is no food supply, which provides a prerequisite for prolonging life.

Habits

1. Very flexible and cunning, afraid of people, the two front paws crawl on the edge of the hole when the activity state is sneaky out of the hole, look left and right, and feel safe before going out of the hole, it likes to establish a fixed route between the nest a food and a water source to avoid danger.

2. Sensitive eyesight, most of the mice are active and foraging at night, nocturnal mice can detect moving objects in very dark light, and daytime mice have better eyesight.

3. The ability to drill holes is high, and the house mouse and rat holes are obvious, often in the wall, the livestock pen, and the warehouse room.

4. Strong memory and food rejection, changing a part in a familiar environment will immediately cause it to be alert, dare not move forward, and dare to move forward after repeated familiarity. If attacked, it will avoid the place for a long time.

In ordinary life, rats are also a kind of animal that we often see and hate. After all, rats carry a lot of germs, and rats are really annoying. So how long does a mouse live?

How high is the IQ of mice? Next, I will introduce to you some common sense about mice.

How long do rats live.

The lifespan of various types of rats is not the same. The landlord should be referring to the house mouse, right? House mice have a lifespan of only two years. The world's largest rat, the capybara, weighs more than 50 kilograms and has a lifespan of up to 12 years.

How high is the IQ pants of the rat.

According to the World Science and Technology Translation News, "The brains of primates are spiral-shaped, but the brains of mice are smooth, but this does not affect the amazing intelligence of mice." Scientists note that the adaptability of mice suggests that they have extremely delicate nervous systems.

Rats are cautious by nature, never eating lethal portions when they eat something fresh for the first time, and will 'notify' other rats when something is wrong and lacking, thus protecting the ...... of the entire colonyThe IQ of a rat is staggeringly high, and the IQ of an adult mouse is equivalent to that of an 8-year-old child. But the report doesn't cite a specific scientific testing process, so it's hard to judge whether it's scientific.

How big is the largest mouse.

The largest Gambian rat has a body overrun of more than 30 centimeters, and if you add the tail, it is about 1 meter. It is reported that the scientific name of this rat is the Gambian rat, which is the largest known rodent in the world and is native to Africa. They can grow up to 91 centimeters long and weigh more than 4 kilograms, making them even larger than domestic cats.

What is the average amount of food eaten by a rat.

1. Rats often eat intermittently, each time the amount of food is not much, but the number of times they eat, such as the small house mouse, which eats less than one gram a day, but is divided into more than 100 to 200 times to eat.

2. Water is closely related to the survival and reproduction of rodents, and rats need to drink water. Brown rats and yellow-breasted rats need to drink 15-30 ml of water per day, and they cannot survive without water; Mus mus have very little water requirements and can survive for months without water if they feed on dry grains.

Vole mice mature early, have strong fecundity, and have a lifespan of 1 to 3 years.

Rats have strong reproductive ability, good adaptability, and a high chance of survival, so the number of oranges grows very quickly. They can mate all year round, have a gestation period of about 21 days, and give birth to 6 to 8 litters a year, and 5 to 10 litters a year. The little mouse hand hall continued to give birth.

A single mouse can reproduce at least a month, and a single female mouse can increase the number of rats in her family by thousands! It's scary.

The rat is too tired from working all night, and it does not know how to maintain health, so it will not live long. You can live for about two years at most. In addition, I live in fear all day long, afraid that the owner will see it stealing the owner's snacks, hide from the patrol team of the hidden cat, and beware of food poisoning.

However, in order to have future generations, they do not adopt family planning, and they give birth to one generation in three months, and each generation is 3---9 generations. This question is too simple, and it depends on the old cat's mind.

Different species have different survival times.

And the grip of the god is related to the living environment, living conditions, and diet of rats.

Take Duan Loss himself as an example, he once raised a dwarf mouse, and when he bought it, he said that he could live for three years, and his body size could not be counted. In the end, Changcheng just bought three big, greedy, like to eat greasy, peanuts, melon seeds, seafood, meat, more than two years to die, suspected of dying of three highs, high nutrition diet hinders their own metabolism, often fall from a height, have not been injured, as long as not sick to live for 3-5 years is no problem.

Rats don't live long, because as long as he eats rat poison, he won't survive for a long time.

That depends on the cat's appetite and appetite.
