A new bacterial species is discovered and classified as an endolith, an extremophile that lives inside rock. If the bacteria were discovered in the permafrost of Antarctica, describe two extremophile features the bacteria must possess.
discuss at least five different examples of extremophiles on Earth and discuss how they thrive in their special environments (or, each person can choose one extremophile to research and share with the rest of the group).
Extrapolate these extreme survival abilities to the kinds of life that might be able to survive in the very different environments throughout our Solar System? Do you think that watery places like Europa or Enceladus would be a better environment to search for life as opposed to somewhere like the clouds of Venus? Why or why not? For more information on possible life in Venus' atmosphere,
For most part of our planet’s history, organisms are microbial. Explain why this is the case?

- Ruminants (like cattle) are herbivores but lack the necessary enzymes to digest cellulose from plants. Part of the digestive tract of ruminants contains a microbial community that can break down cellulose. These microbes gain energy from the plant material, and byproducts of their metabolism provide the host with a source of Carbon and energy.

- what makes areobic or presence of oxygen conditions good for bacteria to growarrow_forwardAt one time, it was thought that living things could be found only where a moderate range of abiotic factors (such as temperature & pH) existed. Since the discovery of extremophiles, micro-organisms that thrive in extreme environments, our understanding of where life can exist has changed. Some extremophiles live in hot, acidic sulfur springs and some even live near the openings of deep ocean hydrothermal vents.Based on our current knowledge of extremophiles that exist on planet Earth, what does the existence of life in such extreme environments say about the possibility of life on other planetsarrow_forwardDiscuss the possibility of life on Mars. Will extremophiles prove useful? Can you explain the upper-temperature limit to life unrelated to the stability of proteins or nucleic acids?
