When there is a cut on your skin, it gives bacteria and other organisms a gateway to enter directly into your bloodstream and could harm the body. By cleaning the wound, you prevent disease and infections from the bacteria.
Answer: Both a and b
Explanation:
The presence of C-C and C-H bonds in fat makes them insoluble in water as they are non polar: do not dissolve in water. These are rich in energy in that their breakdown produces more energy than even carbohydrates themselves.
The answer is D. Global warming causes the ocean temperatures to rise and also its pH to decrease due to increased dissolved carbon dioxide in the waters. Due to the unfavorable temperatures and pH, the algae dissociate from the symbiotic relationship with coral polyps (as a survival mechanism) hence leaving the coral white (coral bleaching). The symbiotic relationship is key for the survival of the coral polyps hence most die following the dissociation. This upsets the reef ecosystem and affects all aquatic organisms that depend on the reef.
I'd appreciate if you attached the article as well. But i'm 90% sure it's option D. A quick search reveals that it was dubbed Black Saturday due to rapid fire growth within Yellowstone park. Option D is really the only one that relates to that at all.
Hope this helps!
0.5. This is because if the cells have not swollen or shrunk then the water potential (and therefore amount of solute) inside and surrounding the cell must be equal.
