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.
Answer:
The length of time for the processes of weathering and erosion to occur are very long, however some quick.
Depending on the force, erosion can happen quickly or take thousands of years.
However weathering usually takes a long time.
Carbon makes four electrons available to form covalent chemical bonds, allowing carbon atoms to form multiple stable bonds with other small atoms, including hydrogen, oxygen, and nitrogen. This allows carbon atoms to form a tremendous variety of very large and complex molecules.
Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
