Answer: The complement components that is the direct cause of the enhanced vascular permeability and chemoattraction in the abraded skin area in this experiment is C5a. The correct option is C.
Explanation:
When the investigator gently abrades the skin from the flank of a mouse, creating a 1 × 2-cm skin window, the investigator caused a mild tissue damage which leads to a complex series of events resulting in the repair of the damaged tissue. These events are collectively called an INFLAMMATION. Inflammation can therefore be defined as the reaction of vascularized living tissue to local injury.
There are many compounds that triggers specific aspects of inflammation and they are collectively called inflammatory mediators. An example is the Complement component 5a. It has the following functions in mediating inflammatory response:
- enhances vascular permeability
- it has the ability to attract other cells to the site of the abraded skin area (a chemoattractant).
B because the climate has to be pretty balanced and if it’s too cold it won’t be habitable and if the climate is too hot it won’t be habitable aswell
Chemical weathering is when things get weathered chemically
Answer:
the atom has equal protons and electrons so it should by without charge
I think this is the correct answer
