In C4 plants, photosynthesis is compartmentalized into two; light-dependent stage and light independent stage. The light-dependent stage occurs in the mesophyll cells of the leaf. Here, CO2 is fixed into oxaloacetate by PEP carboxylase enzyme. The oxaloacetate is then converted to malate that is then transported to bundle-sheath cells (around the leaf veins). The CO2 is then released from the malate and the gas molecule is subsequently fixed by RuBiSCO like in C3 plants. The biggest advantage of C4 photosytheis is that the wasteful process of photorespiration is greatly reduced.
<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 inflammation will not occur with tissue that is dead & has no blood supply. The injury brings a decrease in white blood cells. The Mast Cells play a role in releasing histamine which dilate capillaries and bring about hypermia cause increase blood and swelling and redness to the area
