C. Bleach. Cleans stuff out of everything
Answer:
(a) number of strands (n) = time (t) ÷ proportionality constant (k)
(b) The time needed for the bacterial to double its initial size is 3.36 hours.
Explanation:
(a) Let the rate (time) be represented by t and the amount (number) of strands of bacteria be represented by n
t is proportional to n, therefore, t = kn (k is the proportionality constant)
Since t = kn, then, n = t/k
(b) Initial amount of strands = 300
Amount of strands after 2 hours = 300 + (300 × 20/100) = 300 + 60 = 360
k = t/n = 2/360 = 0.0056 hour/strand
Double of the initial size is 600 (300×2 = 600)
Time (t) needed for the bacterial to double its initial size = kn = 0.0056×600 = 3.36 hours
The purpose of a bacterium's capsule is protection.
<h3>What use does the capsule of a bacteria serve?</h3>
White blood cells may eat and kill pathogens, but capsules could stop that from happening (phagocytosis). Although the precise mechanism for avoiding phagocytosis is unknown, it may occur because the presence of capsules makes the surface elements of bacteria more slippery, preventing the bacterium from being absorbed by phagocytic cells.
Capsules comprised of bacterial defenses and the host. The main function of the capsules of pathogenic bacteria is to prevent opsonophagocytosis or in the case of Gram-negative bacteria, complement-mediated lysis by shielding the bacterial surface from interactions with the host immune system.
