Answer:
Antigen, stabilizers, surfactants, diluents, preservatives
Explanation:
- Antigen: This is part of the protein structure virus or part of its genetic material. These parts are active. But sometimes, the inactivated form of the virus is also included in the vaccine.
- Stabilizers: Avoid other chemical reactions occurring in the interior of the vaccine.
- Surfactants: They prevent the occurrence of sedimentation and agglutination of the elements inside the vaccine.
- Diluent: Used to dilute the vaccine in an appropriate concentration before being used.
- Preservatives: As the word says, preservatives avoid any possible contamination of the vaccine. These elements´ use depends on the doses prepared. If it is only for one-person use, then they are not needed. But if the doses are to be used by more than one person, they need preservatives because once the vaccine is opened it is vulnerable to contamination.

Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilizing the entry of oxygen and the exhalation of carbon dioxide.
Answer:
True
Explanation:
Unlike channel proteins which only transport substances through membranes passively, carrier proteins can transport ions and molecules either passively through facilitated diffusion, or via secondary active transport.
