Explanation:
In the first case is imperative to obtain more information in order to determine the causes of this contagious disease (contaminated seafood may be associated with different types of infections).
<em>Vibrio vulnificus</em> is a Gram-negative pathogenic bacterium associated with the consumption of contaminated oysters. <em>V. vulnificus</em> causes gastroenteritis, necrotizing infections and invasive sepsis.
Jaundice is a condition caused by hepatitis A, B and E viruses, it is a disease associated with poor liver function and the destruction of red blood cells.
<em>Cryptosporidium parvum</em> is a protist parasite (Phylum Apicomplexa) that causes the diarrheal disease cryptosporidiosis. <em>C. parvum</em> parasite is present in contaminated foods and water.
<em>Salmonella enterica </em>is a Gram-negative bacterium transmitted by eating contaminated foods, which causes severe diarrhea, fever and abdominal pain. Salmonella infection may also cause inflammatory diseases and dehydration.
<em>Thichinella spiralis </em>is a parasitic nematode that causes the trichinosis, a disease where larvae migrate to muscle, thereby producing muscle pains and serious pathologies. Trichinosis is caused by eating undercooked meat from contaminated animals.
Answer:
Primary succession can be described as the development of a community in an area where there was no form of life before. For example, an area where volcanic eruption might have occurred.
Secondary succession can be described as an ecological succession which occurs in areas where the previous community had been destroyed by some kind of environmental disaster or human activity like fire etc.
As secondary succession occurs in areas where there was life before that means that the soil of this area will still have essential minerals and nutrients which will support life better as compared to areas of primary succession. In primary succession, the area might not even have soil. The rocks will be converted to soil in these area which will take a lot of time. Hence, an area that goes through secondary succession will likely reach its climax community before an area that goes through primary succession.
I think this one is correct: C. You cannot view live specimens because the necessary preparation kills cells.
Answer:
The cryosphere is the portion of the Earth's surface where water is in solid form. It thus includes sea ice, lake ice and river-ice, snow cover, glaciers, ice caps and ice sheets, and frozen ground. The snow cover has the largest extent, with a maximum area of more than 45 106 km2 (Table 1.1). Because of the present distribution of continents, land surfaces at high latitudes are much larger in the Northern Hemisphere than in the Southern Hemisphere. As a consequence, the large majority of the snow cover is located in the Northern Hemisphere (Figs. 1.15 and 1.16). The same is true for the freshwater ice that forms on rivers and lakes in winter. Both the snow cover and freshwater ice have a very strong seasonal cycle, as they nearly disappear in summer in both hemispheres (Table 1.1).
