Chromosomes are thread-like structures present in the nucleus, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.
Answer:
B
Explanation:
B: Differential survival and reproduction
change enviroment causes natural selection
Out of the three domains, Archaea, Bacteria and Eukarya, the vital differences may be identified in order to classify the cell. Eukaryotic cells possess membrane-bound organelles; on the other hand, the domains archaea and eukarya contain cells are prokaryotic, so they do not have membrane bound organelles. Moreover, they also possess ester linkages in their cell membranes, which allow them to survive more extreme environments (especially true for archaea). By studying the cell membrane of the cell, distinction can be made.
Well mutations can be a positive or a negative feature. Some mutations can be used as a camouflage so stay safe from predators. Other mutation could give off a bright color which would make it hard to stay hidden from predators.
