What are the following:
1. A form of protective mimicry in which an unprotected species, especially of an insect, closely resembles an unpalatable or harmful species and therefore is similarly avoided by predators.
2. A form of protective mimicry in which two or more poisonous or unpalatable species closely resemble each other and are therefore avoided equally by all their natural predators

What is niche
300
If two species of birds are occupying the same habitat, what would help them reduce the competition between these two species?
What is Resource partitioning: decreasing competition between two species, leading to increased niche specialization and less niche overlap.
400
Why are the villi and microvilli so important to digestion and absorption?
What is
• Villi & microvilli are folds that are capable of expansion and add more surface area to the small instestines, which permit large food stuffs to pass through the intestine.
• Also, this is the site where digested food’s nutrients is digested directly into the bloodstream so the cells of the body may obtain nutrients, vitamin, & organic molecules.
400
What are the following:
1. immunity in a means by which the body protects itself from infection by the production of antibodies that target cells, viruses and other presences in the bloodstream that are seen as potentially dangerous, marking them for destruction.
2. Specific mechanism of defense in which T cells destroy antigen bearing cells.
What is 1. Humoral Immunity and 2. Cell Mediated immunity
400
