No humans cannot regrow limbs or organs. This is because of our genes and lack of stem cells. We don't have the right genes and we definitely don't have the amount of stem cells needed to regrow a limb.

Cells make up tissues and tissues make up organs. Cells can change with age and become weaker. Then tissues and organs become weaker and age. Our organs lose their function and they don’t work as well. So that is why your body ages.

The first cell came from the enclosure of self-replicating RNA in the cell membrane. Fossil evidence shows that multicellular life came into existence about 600 million years ago. Eukaryotic cells are larger than prokaryotic cells, they have internal compartments called organelles, they have a nucleus, and have the ability to form multicellular structures. It was from the first eukaryotic cells that all multicellular life has evolved.

Can we regrow limbs? Humans can’t regrow limbs but different animals can like lizards and axolotls. Humans have sequenced the DNA of axiolts and we have found that axolotls have genes that you need to regrow limbs. But when you regrow limbs you can get cancer but axiolts can stop that because they have a system in place to stop cancer.But axolotls have the superpower of regrowing limbs but some mammals like mice can grow the tips of their finger tip back and humans can to as much as bone and skin.

No, currently it is not possible for humans to regrow their limbs. Although there are animals that are able to regrow limbs. An example is an Axolotl. Axolotl's have a unique dna sequence and can grow limbs back in ~3 weeks. Because of this they feed off of eachother while young.

We need to age because your dead DNA needs to regenerate to stay alive. Your cells stop regenerating and that causes you to age and get older. Ones your cells stop regenerating that means that you stop ageing and you most like you are going to die.

The first cell came from an enclosure of self-replicating RNA in a phospholipid membrane. For the first 3 billion years of life there was nothing the first cell slowly synthesized, drawn together and assembled into the first protocell. Some of the oldest cells on earth are single-organisms called bacteria.so the first cell we made more than 3 billion years ago and its made by RNA self-replicating.

Yes! Amphibians and some sea creators can regrow body parts. They do this by growing a specialized bud of cells called a blastema. Where they can regrow limbs in about a week. But not many living things can regrow limbs. Humans don't have any blastema. So there for humans can't regrow limbs but scientist do believe someday we could!.

The first cell was called luka. Luka was generated in the ocean where the ocean ground cracked.when the ground cracked it let out hot water and other metals. That is where lucka was developed.

currently it is not possible for humans to grow back limbs but they beleive that one day it will be possible. some animals can like salimanders. they feed off of each other and after a few weeks a new limb will be fully grown back. this happens because of their DNA sequence.

Aging could have many different reasons of happening, but aging only starts happening once physical growth stops. Aging happens because DNA  replicates in non-dividing cells. If the mitochondrial function declines, then it can cause the death of a cell leading to the death of whole organs.

Yes it might be possible for a brain to repair itself with a little help and a lot of time. There are ways that would help the brain to repair like rescuing cells, cell transplant to replace the bad cells or help targeted cells or modify the inflammatory response. The technology to do it is not yet developed but in the near future maybe it is possible.So it is possible for a brain to repair itself.

As of right now, it is not possible for humans to regrow limbs like exolotles. Axolotls have a certain DNA sequence that makes their limbs cover up and regrow over about 3 weeks. Scientists believe that in the future we will be able to grow limbs artificially.

# data[].attributes.body
For humans not now. Scientists believe it can be possible though. Since we share genes with many animals and the mechanisms they use to regenerate. Scientists think that if we can find the mechanisms for the nervous systems that acorn worms and axolotls use we could one day regrow limbs. Humans have the same genes as those animals, more research could result in humans regrowing limbs.
