Are humans a dead end host for streptococcus pneumonia? If yes please explain why. Thank you!
zlopas [31]

Answer:

No, because Pneumonia can be transferred from one person to another.

Explanation:

Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen.

Have the best day ever! :D

The correct answer is that the bedrock of the Adirondock mountains is formed mainly by regional metamorphism of sedimentary and igneous rocks. The geology of the Adirondock mountains formed around 5 million years ago with rocks  over 1000 million years old. At this very ancient age, the sedimentary and igneous rocks in the Adirondock mountains have undergone extensive heat and pressure hence regional metamorphism of the existing sedimentary and igneous rocks.
