Answer:
Option 2
Explanation:
I did not see the video referenced, but an invasive species is not always brought by people. Furthermore generally there are no limiting factors because it has no natural predators in the environment and often uses up all the resources in that particular environment. Hope this helps!
Answer:
provide protection against pathogens
Explanation:
Which is true about enzymes is: enzymes increase the rate of reactions by lowering the activation energy barrier.
Enzymes are chemical compounds in the form of proteins that act as biocatalysts which function to speed up reactions.
Enzymes work specifically, that is, they can only work on certain substrates by adjusting the shape of the substrate. Enzymes sensor with molecules for substrates to produce compounds through organic chemical reactions that require energy. Some of the reactions assisted by enzymes such as the breaking of large molecules into small ones or the binding of molecules into new molecules. Enzymes can do that because of the influence of the activation energy that every chemical reaction has.
Activation energy is the energy required to break down the reactants. The role of enzymes is to lower the activation energy limit needed to start reactions.

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.
Answer:
second law
Explanation:
becuz it states that force os directly proportional to the product of acceleration and mass
f=mxa
