<span>A diseases may be classified as either communicable or non-communicable. Communicable diseases are caused by pathogens who inhabit a host, man (I'm not saying man is the only host or man is necessarily the final host; there could be many host) who in turn passes the disease to another. Pathogens are viral, bacterial, parasitic and fungal. There are several stages before the pathogen metamorphoses into a full-blown disease. The stages in which several events happen builds up before the pathogen affects the final host is called a communicable disease chain. There are six stages ( Pathogen, reservoir, portal of ext, mode of transmission, portal of entry and susceptible host) in the communicable disease chain but the step a nurse shouod take is
1. Destroy the second link (Reservoir) by thoroughly sanitizing the environment. Obviously, this is where the Pathogens live. If the reservoir is taken care of; there's no way they could infect the host.</span>

The sun does however, revolve about a point in the centre of our galaxy. Taking entire solar system with it at a speed of 220 km/s. This period of orbit takes 225 million years. The sun revolves at about once every 25days at its equator and up to 30 days near its poles.
The correct answer for this question is this one: C:"It provides support." There exists the same question with the same choices. The function of the cell structure that is labeled X is that it provides support.
The rate of reaction in chemistry tells us how fast a reaction will occur from start to end.
