NASA reignited our hopes of finding alien life when it announced the first direct evidence of liquid water on Mars. But before we start indulging in fantasies of space crabs and reptilian beings, we ought to remember that Mars is a frigid world with a thin atmosphere. And that raises an obvious question: What sorts of life forms could actually live there?
Any life on Mars today is almost certainly microbial, but beyond that, we can’t be sure of anything until we actually dig it up and study it. Still, we can make some educated guesses about the nature of Martian life, by taking a deep dive into some of the weirdest biology on planet
Explanation: As the DNA is present in the nucleus, there is compartmentalisation and the process becomes more efficient without the interaction of external bodies. The membrane of the nucleus protects the DNA from injuries.

Answer:
This question lacks options, options are:a.Eating and breaking apart food converts carbon to other elements.b.Eating and breaking apart food converts other elements into carbon.c.Eating food involves taking up carbon dioxide.d.Eating and breaking apart food releases carbon dioxide as a byproduct.The correct answer is d.
Explanation:
Heterotrophs are organisms unable to photosynthesize, so they obtain energy and carbon through the consumption of other organisms.Carbon enters all the trophic networks through the autotrophs, these create their own food by fixing carbon, that is, they capture the carbon dioxide that forms the air or dissolved in water and use it to produce organic compounds. Heterotrophs, which feed on other beings (obtain their food from organic sources present in their environment), consume organic molecules and thus organic carbon passes through the chains and trophic networks. Carbon atoms through respiration in the form of carbon dioxide are released.
