Cell wall - Adds structural support to the cell. Holds the cells together
Cell membrane - Serves as a barrier to the cell and allows more nutrient and molecules to move in and out of the cell without letting things that can harm the cell in.
Outer membrane - Serves the same basic functions a the cell membrane. (Depending on how complicated the class your in is, I would visit this website for more information... https://en.wikipedia.org/wiki/Bacterial_outer_membrane )
Pili - Help the cell move and attach the bacteria to surfaces are other cells.
DNA - Contains the genetic instructions on what the cell can physically do, operate, and reproduce.
Flagellum - Helps the cell move. It kind of acts like a propeller for the cell so that it can move around.
TRUE.
Infection is the invasion or colonization of the body by potentially pathogenic microorganisms.
Answer:
the atmosphere
Explanation:
because coal-powered electrical plants produce air pollution, which is one of the main causes of global warming, so if it was substituted for hydroelectric or geothermal sources the amount of air pollution would decrease greatly.
The moon affects wildlife because of its three profound influences on Earth. Time, light, and tide. For many animals, (mainly birds) the moon is essential for migration and navigation. Also, lions hunt the best during the darkest nights of the lunar month. Wildebeests and other prey of lions learn to avoid going out during dark nights to stay safe. Animals learn different things with the moon, whether it be safety, when to reproduce, or when to migrate.
I’m not sure if this is what you’re looking for, but these are some key points you could use in your story if you build around it. Good luck!
The physical barrier that the mRNA must pass is the nuclear membrane.
The process of gene expression involves two main stages; transcription ; the production of messenger RNA by the enzyme RNA polymerase, and the processing of the mRNA molecule. Then the process of translation which takes place outside the nucleus, therefore the mRNA must cross the nuclear membrane to enter the cytoplasm.
