Well in my words, The vaccine is the weakened or dead version of the virus(pathogen). This actually prepares the body to be un-affected if it ever comes in contact with the virus (pathogen) again. After the vaccine is injected your body produces memory cells. These help your body become immune to the same virus (pathogen) twice. So basically it helps protect your body from dangerous viruses or pathogens, and develops immunities against them.
I really hope this helped :D
You would generally not be able to recover fossils from volcanic or plutonic rock, so looking around in an area on active volcanic islands would yield nothing.
You always want to look in the layers of sedimentary rock for fossils. The Grand Canyon would be a great place to see these layers as well as a shallow ocean because you may find the remains of prehistoric shark teeth or bones protruding through the surface of the sand.
The answer is Active volcanic islands.
If this is a question in which you can choose more than one answer it may be smart to also choose a shallow ocean as well. This is because it is difficult to get the tools and materials necessary down in the water and would be difficult to get deep enough underneath sand to start digging into actual fossil bearing rock.
So in that case, the answer would then be both Active volcanic islands and A shallow ocean.
The buoyant force is equal to the weight of the fluid displaced by an object when the object is submerged into a liquid. Gravitational force is the force of gravity, and friction is the force created when two objects rub up against one another when at least one of the objects is in motion.
This would be an example of negative feedback because the body isn’t trying to surpass a set point. It’s trying to maintain the amount of food in the stomach at that point.
