Answer:
The correct answer is D.
Explanation:
Bordetella pertussis is a gram-negative coccobacillus that causes a disease called whooping cough.
The bacterium infests the patients by colonizing lung epithelial cells. To do so, it requires adhesins, called filamentous haemagglutinin, fimbriae and pertactin. Once the bacterium is attached to the lung epithelial cells, it produces a cytotoxin that prevents their cilia from moving.
Another virulent factor from B. pertussis is the pertussis toxin, which alters host immune system through the inhibition of phagocytes response to it.
Answer:
Hydrophobic.
Explanation:
The plasma membrane or cell membrane is made of the lipid bilayer and the proteins are embedded in the this layer. Carbohydrates are also exposed to the cell surface in association with proteins and lipids.
The interior of the cell membrane is hydrophobic due to the arrangement of the lipid bilayer. The hydrophobic part of the lipid membrane are associated with each other that makes the interior of the cell membrane hydrophobic and small molecules easily diffuse through the membrane.
Thus, the correct answer is option (c).
