3.) Testing multiple variables.
Answer:
Innate immunity is a nonspecific defense mechanisms that play its role as soon as an antigen appear in the body (it is relatively rapid but nonspecific and because of that it is not always effective)
Explanation:
The barries of innate immunity are:
Skin: At Epidermal surface, its protective aspect are keratinized cells that lives on the surface, known as Langerhans cells.
Skin sweat or secretions: Their specific defense is sweat glands and sebaceous glands, and their protective aspect is low ph and washing action.
Mucosal surfaces: they are at the mucosal epithelium, and their protect aspects are nonkeratinized epithelial cells.
Oral cavity: They defend salivary glands through Lysozyme
Answer:
A magnet keeps a cabinet door closed. The Sun pulls on Earth as Earth moves around the Sun. The protons in the nucleus of a carbon atom are held together.So this is an example of the strong force in action.
The two organisms that are most closely related according to Linnaean taxonomy are <em>Felis catus</em> and <em>Panthera pardalis</em>, because they belong to the same family
<h3>What is taxonomic classification?</h3>
Linnaean system of classification consists of a hierarchy of groupings called taxon. Each taxon is arranged in a hierarchical order.
The hierarchical arrangement of the taxon are as follows:
- Kingdom
- Phylum/Division
- Class
- Order
- Family
- Genus
- Species
These taxa are arranged from the most inclusive to the most exclusive i.e. members of the same species are the most closely related in that order.
This suggests that <em>Felis catus</em> and <em>Panthera pardalis</em> are the most closely related because they belong to the same family.
