I believe the correct response would be A. Elements arranged by increasing atomic mass, this was not included in Dmitri's periodic table. Since elements are arranged according to atomic number, the heavier elements are in fact placed in the rows closer to the bottom of the table.
Answer:
it's the second one/B because it's the only one that is correct :)
Eukaryotic Cells (animal and plant cells) have organelles. These organelles have many functions like storing genetic info, making energy for the cell, making proteins, etc. They help the cell run and work.
Pili are the filaments that help some bacteria stick to surfaces and exchange plasmids through conjugation.
Pili are hollow, hair like appendages that are found on the surface of some bacterial cells. Pili are composed of a special protein (known as pilin). Pilia act as a means of attachment of bacteria to surfaces (such as their host) and it is also used by bacteria to exchange their genetic material (plasmids) in the mating process between cells (known as conjugation).
Carbon is found in the atmosphere mostly carbon dioxide. Animal and plant respiration place carbon into the atmosphere.When you exhale, you are placing carbon dioxide into the atmosphere. Carbon is found in the lithosphere in the form of carbonate rocks.
