The correct answer is A. An infection that migrates via the bloodstream
Explanation:
Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.
Algae living on a sloth is considered an example of mutualism because both of them benefit from each other.
Mutualism is one of the symbiotic relationships in which both the two species living together benefit in one way or another. A considerable example of such a relationship is between algae and a sloth.
The algae provide camouflage to the sloth and protect it from predators while the sloth provides shelter to the algae for its growth. The sloth also gets nutrition from algae which perform photosynthesis and synthesize food.
Another mutual relationship is observed between the aphids and ants. Aphids produce honeydew as a waste product of their diet which is consumed by ants. While ants protect the aphids from predators and parasites.

D should be the correct answer. Hope this helps!
The basic structure of a cell membrane is in three parts; the internal membrane surface, the external membrane surface and the intervening phospholipid material. This intervening material is impermeable to ions and polar molecules and it prevents polar solutes likie amino acids from moving across the membrane but permits the passive diffusion of hydrophobic molecules.. The external and internal cell membranes are selectively permeable and can regulate what comes into or goes out of the cell and in so doing allows for the transport of materials needed for survival.
