No. There is no evidence of any life of Mars, certainly not multicellular life.
No
Humans do not have any insects, neither do other animals (except insects).
Humans, no. Unmanned spacecraft, yes.
Nope. They all survived. We have not yet sent any humans to Mars, if that was what you meant. Except for Hollywood, they've sent tons of people to Mars
I think its extremely unlikely that there is life on Mars .One the main reasons is that mars' atmosphere is made up from carbon dioxide (95.32%) this means that if humans breathed it in it would kill us this is because carbon dioxide is poisonous . Also there is little water on mars (0.03)so it would be very hard for any bacteria, plants or humans to survive with so little waterHope this helps X
nothing that has ever been discovered
Minute pirate bugs in bed do not pose any harm to humans. They are beneficial insects that feed on pests like aphids and other small insects.
There are more insects than any other animals in the world.I'm guessing insects. After all this research, there are still undiscovered insects. It is not plants because plants are decreasing with global warming (esp. trees). However, the human population is increasing. I also know that particles are the most in this world, because everything is made up of those particles. Really there isn't a real answer to this question but I guess you could say particles, humans or insects.
There are no known man-eating plants in reality. While there are carnivorous plants that trap and digest insects for nutrients, they are not capable of consuming larger animals like humans. Any tales or stories of man-eating plants are purely fictional.
Spiders do not harm plants directly. In fact, they can be beneficial to plants by preying on insects that may damage them.
Our current level of technology does not provide a suitable, long term functional plan for any form of colony on Mars (At our current technology level)
Yes, there are a number of plants that are toxic if ingested and also animals that can be dangerous to humans.
