What are 6 signs of life that scientist use to determine whether something is dead or alive?
The six signs of life that scientists use to determine whether something is dead or alive are responsiveness to stimuli, growth and development, reproduction, regulation of internal environment, energy processing, and adaptation to the environment.
If a hamster is stiff does it mean its dead?
If it is like that, cold and not breathing, yes, it is dead.
What do life scientist study?
Life scientists study living organisms, including plants, animals, and microorganisms, as well as their interactions with their environment. They conduct research to understand biological processes, genetics, evolution, and ecosystems, among other topics. Their work helps expand our knowledge of life and contributes to advancements in medicine, agriculture, and environmental conservation.
What theories do scientists have about aliens?
Good question !!! Is there ACTUAL proof of any kind that there is life in space?? Most planets are either to hot, cold, or windy to harbor life. do some research on the planets & u will find out what I mean. Yours truly, Bethany a.k.a. pianoplayer
What has scientists learned about otzi?
Scientists have learned that Ötzi the Iceman, a 5,300-year-old natural mummy discovered in the Alps, provides invaluable insights into Copper Age life. Analysis of his clothing and tools indicates he was skilled in crafting and had access to diverse resources. His body revealed evidence of a diet rich in grains, meat, and plants, as well as signs of health issues, such as arthritis and a high level of copper in his hair, suggesting exposure to metalworking. Additionally, Ötzi's tattoos, which may have served therapeutic or symbolic purposes, highlight the cultural practices of his time.

How do scientists know there is no life on mars?
They sent robots to look for it, so far they've found no signs of life.
Did scientists discover life on mars?
There is currently no definitive evidence of life on Mars. Scientists continue to explore the planet and search for signs of microbial life or past life, but no conclusive findings have been made yet.
Do other planet or moons might support life no or yes?
Yes,Other planets could scientists believed some life were on other planets and signs of life
What happens if i marry an alien while they are in the US on holiday?
Then you have found signs of extraterrestrial life and should tell scientists immediately.
What characteristics do you think scientists will be looking for on these other planets?
Scientists will primarily look for signs of liquid water, as it is essential for life as we know it. They will also seek chemical biosignatures, such as oxygen or methane in the atmosphere, which may indicate biological processes. Additionally, the presence of suitable temperature ranges and stable climates will be critical factors in determining a planet's habitability. Finally, the planet's geological activity and magnetic field could also provide insights into its potential to support life.
Is there prove of lifes on mars?
So far, scientists haven't found solid proof of any form of life outside of Earth. However, scientists have found signs of life on Mars, and some believe that bacterial life exists there. However, we still are more than 80% sure that there is no life on Mars.
Once these rocks are observed by scientists, do you think we will have more answers to the question of whether or not life was once on Mars?
yes I think they will
Scientists look for what molecule when they are investigating the possibility of life on other planets?
Scientists look for molecules such as water, methane, and organic compounds like amino acids or nucleotides when investigating the possibility of life on other planets. These molecules are considered essential for life as we know it.
Can scientists reconstruct the history i of life on earth by determining the age of fossils?
Yes, scientists can reconstruct the history of life on Earth by determining the age of fossils through various dating methods, such as radiometric dating and stratigraphy. By establishing the chronological sequence of fossilized remains, researchers can understand evolutionary trends and the emergence of different species over time. This information, combined with geological data, helps to create a more comprehensive picture of life's history and the environmental conditions that influenced it.
Why do you not believe in the existence of extraterrestrial life?
There is currently no conclusive evidence to support the existence of extraterrestrial life. Scientists continue to search for signs of life beyond Earth, but until concrete proof is found, many remain skeptical.
A half - life of an element is important for determining the what of a rock?
The age of the rock. By measuring the amount of parent and daughter isotopes in a rock sample and knowing the half-life of the radioactive element, scientists can calculate the age of the rock.
