<span>The correct answer is b. ocean and freshwater system conditions generally remain constant throughout the year. This is not true because they are very different. For examples, freshwater rivers can completely freeze during the winter while oceans can't freeze completely, not even a bit. Also, the animals inside have completely different body structures to fight these changes.</span>
<span>While Acid fast bacteria retain carbol fuchsin after acid-alcohol treatment, non- Acid fast bacteria are decolorized by acid-alcohol.
Bacteria of genus mycobacterium are best stained using acid-fast method. A mixture of Phenol and fuchsin is carbol fuchsin. In acid-slcohol, acid is hydrochloric acid.</span>
Adhesion depends on binding between specific molecules on both the host and pathogen so that the pathogen can gain a stable foothold on host tissues.
<h3>What is adhesion?</h3>
In epidemiology, adhesion makes reference to the process in which pathogen and host interact during an infection.

These pathogens can be any type of microorganism able to cause harm to the host (e.g., bacteria and fungi).
