san4es73 [151]

Electricity could be discovered using batteries based on zinc or lead, but without copper wiring it would remain little more than a scientific curiosity. Electric motors and generators require large amount of wiring, so they are impossible to build on large scale in this world

What is a communicable disease chain? what steps can a nurse can take to break a link within the communicable disease chain?
Kaylis [27]
<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>

Do you think that fungal cells have turgor pressure? Design an experiment to test your hypothesis.

Yes because they still need water to function. Fungal cells are interesting in that they have a cell wall like plant cells, but that cell wall ismade up of chitin.<span>They are also heterotrophic, normally feeding on dead organic material. Hope it helps. </span>
