Primary response:
Programs the immune system to remember a particular disease agent by allowing it to "practice" on a weakened or killed version of the pathogen
Body may have a fever during this process
secondary response:
If a pathogen invades the body following a vaccine, the immune system can respond in a faster and greater magnitude than the primary response, which results in the creation of more antibodies to fight the pathogen and more memory cells to fight it in the future
The most internolecular force between molecules is found in solids. Some solids require a lot of energy to chang state
The least intermolecular force between molecules is found (evidently) in gasses. Gas particles are free to move and fill their container. This means that between molecules there is weak attraction.
NB: Intermolecular forces may be weak in compounds, this does not mean that the bonds WITHIN molecules are weak. You can have strong covalently bonded molecules for example, but that have weak intermolecular sorces of attraction BETWEEN the molecules.
Hope it helps!
C. An outer cell membrane surrounds extracellular fluid before a vacuole forms containing the fluid
it's a type of cytosis vesicular active transport that involves the invagination of the plasma membrane to introduce a liquid in the cell in contrast with the phagocytosis which is made for solids
