The answer is Vaccination.
Acquired or adaptive immunity is the body's third line of defense. This is protection against specific types of pathogens. Acquired immunity may be either natural or artificial in nature. Both natural and artificial immunity have passive and active components. Active immunity results from an infection or an immunization, while passive immunity comes from naturally or artificially gaining antibodies.
Answer:
The answer is C
Explanation:
Proteins that were sinthesized in the endoplasmic reticulum are able to leave this organelle inside vesicles that are formed through evagination of the reticulum membrane. These vesicles can merge with the golgi membrane, spreading its contents inside the golgi apparatus. This process can be repeated through all of Golgi's cisternaes, and when the last cisternae is reached, these vesicles can be directed towards the plasma membrane. Once the vesicles and the plasma membrane are merged, all the molecules that were contained inside the vesicle are exported from the cell into the extracellular space.
The concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
<h3>What are liposomes?</h3>
Liposomes are vesicles which are made up of a lipid bilayer membrane.
Liposomes are important as delivery vehicles for substances such as drugs.
Ultrasonication is a method of liposomes preparation.
Solution of liposomes is dependent on the size.
The larger the diameter, the smaller the l elution volume. Also, increasing lipid concentration will decreases elution volume.
Therefore, the concentration of lipids necessary to prepare liposomes with a diameter of 250 nm is 0.30 mM.
