Most tissues in the body are capable to repairing themselves but the type of tissue that is not readily repaired when damaged are is the tissue of the nervous system. This is due to the complexity of the brain and the spinal cord. Once damage is not, permanent paralysis happens.
Animals would be out, because they do not produce their own food.
Fungi decompose other matter and break it down to get glucose and other minerals. They do not produce food either.
Protists are the 'odds and ends' kingdom. Some protists are plant-like, animal-like, or fungus-like. So it wouldn't contain ONLY producers.
The answer to this would be Plants because they generate their own food through the process of photosynthesis, creating glucose in photosynthesis and breaking it down for energy in cellular respiration.
No, marsupials are mammals like opossums, kangaroos, wombats, and bandicoots who all have pouches and give birth to live young that are not ready to live in the outside world until later as they are not fully developed. Therefore they live in their mothers pouches until they are mature enough. They mainly live in Australia, New Guinea and America.
The use of mRNA and reverse transcriptase is part of a strategy to solve the problem of post-transcriptional processing. RNA is synthesized in the process of transcription and then transferred to the cell cytoplasm where it is translated into protein. Post transcriptional modification or processing is a process where the primary transcript RNA is converted into mature RNA.
Density-dependent factors include disease, competition, and predation. Density-dependant factors can have either a positive or a negative correlation to population size. With a positive relationship, these limiting factors increase with the size of the population and limit growth as population size increases.
