<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>

Answer:
A. 1
Explanation:
pH is a measure of how acidic/basic a substance is. The range goes from 0 - 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
note: the closer you are to the neutral the weaker it gets.
Answer:
tundra, taiga, temperate grassland, rainforest
Explanation:
Tundra is known to be the coldest of all the biomes due to the high latitudes in which these areas are found. In this biome, the growth of the trees is limited by the low temperatures and the growing season is restricted to the summer season. The taiga is a type of biome composed of forest found in the subarctic areas, it is for that reason that taiga regions are also called boreal forests. Temperate grasslands are areas where grasses are dominant with very variable temperatures depending on the season (i.e. summer to winter seasons). In this biome, trees are relatively uncommon. Finally, the rainforest is the most diverse tree-rich biome where the high temperature and humidity conditions are optimal for life.
