It depends on the region you are in. I will give a basic overview.
Canada- Over 80
USA- 77-80
Mexico- 75-77
Central America- 70-72
This is South America in General- 60-80 depending on which countries
Europe- 77-over 80
Asia can get anywhere from-65-72
India and countries bordering India- India is 67 and the bordering countries are 40-67
Middle East-70-77
Africa- Under 40-75
Australia-Over 80
Be more general next time!
The average life span for humans in the year 1850 was around 40 to 50 years due to factors such as high infant mortality rates, limited access to medical care, and lack of advanced healthcare technology.
There are many types of cycles but I'm going to assume you're talking about the life cycle, life cycle is continued and never stopped until the creatures all have pass away. The life span is an average life time usually in years, like the hamster/gerbil life span is 3-4 years a dog life span is 12-14 years. The life cycle would just be, well life.
The average life span has increased by about 30 years since 1900 due to advances in medicine, public health measures, and improved living conditions. This has led to a significant increase in life expectancy globally.
Life span is one life time. Life cycle is from the animal to its offspring to their offspring etc. Butterflies, for example: egg -> caterpillar -> chrysalis -> butterfly -> egg etc
The lifespan varies greatly among different species. Human lifespan is typically around 70-80 years, while small animals like mice may only live for a couple of years. Some species of trees can live for thousands of years.
A turtle has a longer life span because a silkworm can die by someone killing them
Only Batman knows
So short, it'll make you cry.
The general (and very rough) rule of thumb is that a mammal's natural life span is usually about a billion heartbeats. Humans are an exception; we live about 2 billion heartbeats.
The relationship between a humans pregnancy length and average life span is not so different than other mammals. It appears to be closely related to size.
Natural killer cells have a short life span, typically ranging from a few days to a couple of weeks. They are continuously produced by the body to maintain immune surveillance and respond rapidly to infections or malignant cells.
Because animals have a shorter life span.
Quite high. There life span is roughly same as normal humans.
The vast majority of organisms have a shorter life span than humans, everything from bacteria to insects to hummingbirds to dogs. Only a few have longer life spans.
The average life span of humans in 2050 is projected to be around 80-85 years, depending on various factors such as advancements in medical technology, lifestyle choices, and access to healthcare.
The answer is 65 years. (I am an Anthropology grad student).
It is just natural!
