Answer:
Streptococcus Pneuomiae
Explanation:
I think that S. Pneumonae would be the most characteristic example of a pathogen with a capsular polysaccharide virulence factor.
This is a gram-positive, catalase-negative, alpha-hemolytic and optochin-sensitive bacterium. It is responsible for a broad spectrum of disease, most importantly community-acquired pneumonia, sinusitis, otitis media and meningitis in adults.
Sign and symptoms of an S. Pneumoniae disease can vary, but it commonly includes fever, difficulty breathing, productive cough, headache and, in the case of meningitis, neck rigidity, and diminished alertness.
Interestingly, there are other Streptococcus species (i.e. Streptococcus Viridans) that share some of S. Pneumoniae characteristics and is clinically relevant (can cause heart inflammation, also known as endocarditis, in patients with prosthetic heart valves), but lacks the polysaccharide capsule, effectively making this organism a much less virulent one.
The answer is B. Chloroplasts absorb sunlight to enable a plant to make food. This is because these organelles contain special pigments like chlorophyll that enable them to absorb sunlight and its energy to be used later by the cell!

Scientists can find out when the volcano erupted by determining the age of the fossils in the ashy layers of sediment in area.
<h3>What is a Volcano?</h3>
This is defined as a vent or opening where lava erupts on to the surface of the Earth.
The age of the fossils in the ashy layers of sediment in area will help to determine the time when the volcano erupted.
