Answer:
The correct answer is option - a surface protein allowing the pathogen to bind to host cells
Explanation:
Virulence factors are substances or molecules released by pathogens such as bacteria, fungi, viruses and protozoa that enhance their function effectiveness and enable them to get the following-
Attachment to host cell and surface.
Evasion of the immune response of the host.
Suppression or inhibition of the immune response of host.
Getting nutrition from the host cells
Thus, the correct answer is option - a surface protein allowing the pathogen to bind to host cells.
Answer:
A) its elliptical orbit and tilt on its axis
Explanation:
Earth revolves around the sun in an elliptical path. Its axis is tilted to about 23.5° from the vertical.
These two factors determine the global climate on the Earth.
Due to elliptical orbit, the earth is sometimes closer to sun than the rest of the time. When it is closer the global temperature rises by 5 degrees. Due to the tilt of the Earth, seasons occur. The hemisphere which points towards the sun has summers where as which points away has winters.
Thus, the long-term climate change is effected by elliptical orbit and tilt of the axis.
Dinoflagellates are large group of flagellate eukaryotes (multicellular organisms) that constitute the group dinoflagellata. Red tides is a common name for alga bloom (large concentrations of aquatic microorganisms ) which when caused by a few species of dinoflagellate and the bloom takes on a red or brown color. Therefore, the answer to the question is red tides.
