Maternal passive immunity is a type of naturally acquired passive immunity, and refers to antibody-mediated immunity conveyed to a fetus by its mother during pregnancy. Maternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells.
Adaptive immunity works slower than innate, and is more specific. There are two types: passive and active. Passive immunity occurs when antibodies are passed from one person to another, as through transfusion for example. The active immunity involves two types of white blood cells - T-cells and B-cells.

Antiprotozoal drugs will be much cheaper to develop than antibacterial drugs as we have extensive knowledge of most of eukaryotic metabolic pathways. But some of their metabolic pathways are still unknown as they have multiple metabolic pathways.
Explanation:
Antiprotozoal drugs are much cheaper than antibacterial drugs.
But those drugs have some side effects. most of those drugs possesses side effects. Sometimes this could be fatal if they are not taken by the doctor's recommendation.
Protozoans have multiple metabolism pathways, though most of them are known but there are still so many unknown facts to reveal.
Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light. Electrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscope
Cytoplasm is the organelle that keeps the other organelles together. The nucleus is the cell that conducts and instructs the cells activities. The ribosome contains RNA. Cell wall is the most reasonable.
