<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 statement 'obtaining embryonic stem cells for use in therapy requires the destruction of embryos' would be used in an argument against the use of human embryonic stem cells for therapy. It is a type of stem cell therapy.
<h3>What are embryonic stem cells?</h3>
The embryonic stem cells are cells obtained from embryos that have the property to divide and specialize into different tissues.
The embryonic stem cells can be differentiated in the laboratory for the development of specific cell lineages.
The therapy using embryonic stem cells involves the use of these types of cells and the destruction of an embryo.

Well, to answer your first question, Because there are places on Earth that are both biologically rich — and deeply threatened. For our own sake, we must work to protect them. and for your 2nd question, 3 characteristics of magnetic reversal are: field, bar magnet, and molten material. Hope this helps
Each layer of earth has a different density the more in you go with the layers the more density is going to show up.
Crust-2.2g/cm^3
Upper mantle-3.4g/cm^3
Lower mantle-4.4g/cm^3
Outer core-9.9g/cm^3
Inner core-12.8g/cm^3
Hope I helped in something, Sorry if I didn't gave it my best shot:)
