Explanation:
Homeostasis is the term use to describe the internal stability needed for survival of an organism, including humans and animals while equilibrium is narrow to specific mechanisms.
Answer:
B. lined up perpendicular to the long axis of the bone, in the direction of perforating canals.
Explanation:
Osteons are formations of concentric bone layers (lamellae) that tend to <em>run parallel to the long axis of a bone.</em> They sorround the Haversian canal, a canal that contains blood vessels that supply the osteocytes and are the structural unit of compact bone.

Answer:
True
Explanation:
Bacteria generate toxins which can be classified as either exotoxins or endotoxins. Exotoxins are generated and actively secreted; endotoxins remain part of the bacteria. Usually, an endotoxin is part of the bacterial outer membrane, and it is not released until the bacterium is killed by the immune system.Most viral infections eventually result in the death of the host cell. The causes of death include cell lysis, alterations to the cell's surface membrane and various modes of programmed cell death. Some viruses cause no apparent changes to the infected cell.
The manufacture and characterisation of silver oxide films for application as bactericidal coatings are described in the research.
- There are reports on the synthesis parameters, dissolution/elution rate, and bactericidal effectiveness.
- Reactive magnetron sputtering was used to generate the synthetic conditions necessary to produce AgO, Ag2O, or combinations of AgO and Ag2O on surfaces.
- All of the examined bacterial strains are hampered from growing by the coatings, which exhibit good adherence to numerous substrate materials.
- <em>Escherichia coli</em> and <em>Staphylococcus aureus</em> can be killed by the coatings, which also show a distinct zone of inhibition against bacteria growing on solid media and the capacity to quickly stop bacterial growth in planktonic culture.

I'll choose Golden Retrievers:
These dogs where created for duck-hunters. Their purpose was to go catch the ducks that fell on the lake/river once they were shot by the hunter - here we see how they serve (or actually served) men.
Nowadays, Golden Retrievers are known to like water a lot, and to be very playful with it - and here is where we see a genetic adaptation. They needed to be in water, and were modified to like it.
