The function of chemical substances such as histamine and leukotrienes would be to stimulate inflammation. Leukotrienes is an example of eicosanoids which play a key role in the pathogenesis of inflammation. They are synthesized in the leucocytes from arachidonic acid via the actions of 5-lipoxygenase. The release of histamine serves as an important part of the body's immune response; when the body comes into contact with an allergen, such as pollen or animal dander, histamine is released by the body to the site of contact and triggers inflammation.
Answer:
A trait that is altered easily by small changes in diet.
Explanation:
The phylogenetic tree explains the evolutionary relationship between the organisms. The phylogeny of the organisms will depend on the difference and similarities in their genetic or physical characters.
The traits that are used in phylogeny must be constant and present in the ancestors or in atleast a group. The trait that can be easily modified or changed cannot be used for the study of the evolutionary relationship. Hence, trait which is altered by diet cannot be used in phylogenetic analysis.
Thus, the correct answer is option (C).
Standard microbiological practices (SMPs) should be practiced by microbiologists to protect herself against the pathogens.
What are the Safe Practices for the Microbiology Laboratory:
- Treat all microorganisms as potential pathogens.
- Sterilize equipment and materials.
- Disinfect work areas before and after use.
- Autoclave or disinfect all waste material.
- Never pipette by mouth.
- Clean up spills with care. Wash your hands.
What is Biological Safety Level (BSL):
BSL is a biocontainment designation system with requirements intended to protect personnel from potentially harmful pathogenic exposure in a research or manufacturing environment.

It's called hypoxemia, it's low levels of oxygen in the blood, to be more specific, it's oxygen loss in your blood from your arteries. It can cause respiratory disorders, and tissue hypoxia, as a result of the blood not providing much oxygen to your body.

Answer:</h2>
The principle is <u>4) Archimedes' principle</u>.
<h2>
Explanation:</h2>
Archimedes principle, found by the old Greek mathematician and creator Archimedes, expressing that any object totally or incompletely submerged in a liquid (gas or fluid) very still is followed up on by an upward, power the size of which is equivalent to the heaviness of the liquid dislodged by the body.
The volume of dislodged liquid is identical to the volume of an item completely drenched in a liquid or to that portion of the volume underneath the surface for an article halfway submerged in a fluid. The heaviness of the uprooted bit of the liquid is comparable to the extent of the buoyant force.
