The recipient will only temporarily benefit from passive immunity for as long as the antibodies persist in their circulation. This type of immunity is short acting, and is typically seen in cases where a patient needs immediate protection from a foreign body and cannot form antibodies quickly enough independently.

One of the most common and well known atmospheric optics, the rainbow is formed when sunlight is refracted and reflected by water. A collection of droplets in the atmosphere — whether from rain, a waterfall, a sprinkler, etc. — disperses the entire visible light spectrum at an angle, resulting in the circular shape.
Answer:
D) choose the tree that represents the fewest evolutionary changes, either in DNA sequences or morphology.
Explanation:
Parsimony is a concept applied while constructing a phylogenetic tree. According to it the best tree is constructed by fewest evolutionary changes, either in DNA sequence or morphology. Complicated changes should be present as less as possible in a tree.
For example, suppose vertebrate relationship can be explained using two trees. Tree A has six evolutionary changes and evolution of bony skeleton occurs once. Tree B has seven evolutionary changes and evolution of bony skeleton occurs twice at different spots. Tree A will be preferred because it explains the vertebrate relationship in a less complicated way than Tree B.
