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 correct option is: GRATINIC ROCK IN THE OCEAN FLOOR.
Sea floor spreading refers to the process by which molten materials add new oceanic crust to the ocean floor. This process occurs slowly across the earth's middle ocean ridges. Harry Hess formulated an hypothesis to explain the phenomenon of sea floor spreading and all the above options support his hypothesis with the exception of option C.
More widely available food chain for other predators, an increase in population of the prey.
Active transport is the movement of molecules against the concentration gradient from an area of high concentration to an area of low concentration, which requires energy in the form of ATP. Hope this helps! ^.^
Answer:
"Option B. The tilt of the moon´s orbit around the earth
" limits the number of eclipses per year
<u>Explanation</u>:
The moon's orbit is tilted only by 
. Around the sun when the earth and moon move, the tilt of the moon changes according to the direction of the sun. When the same thing occurs to the earth, the seasonal changes occur. The theory is all related to moon's formation. Due to this tilt the moon's road near the stars changes slightly in every month. The inclination is with respect to the ecliptic plane. If this inclination was absent then we could have felt the eclipse more frequently.
