This is a mesh-like layer found just outside the cell membrane of most bacteria and makes up the cell wall.
Gram negative organisms have very little whereas gram positive organisms have a very thick peptidoglycan layer.

The correct answer is 4. They convert salt and iron into energy and nutrients.
Explanation
Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.
Answer:
-all species change gradually over time.
Explanation:
Mutation often results from cell replication and division. These occur as small, random, errors within the genetic code that become more common or stable within a population over time as traits.
As organisms live within varying niches, environmental changes may render some genetic traits obsolete. However, others may become more beneficial as an adaptation. These adaptations, which make an organism and its offspring suited to a niche, and more likely to survive and reproduce become inherited- this process is called evolution.
Answer:
Cellular Stomach
Explanation:
Containing acid and several types of digestive enzymes, lysosomes digest unwanted organelles in a process termed autophagy, from the Greek words for “self” and “eat.” The multipurpose lysosome also processes proteins, bacteria and other “food” the cell has engulfed.
