Answer:
A power point overload occurs when you exceed the maximum amperage of the electrical circuit you are using. This can be caused by plugging too many appliances into the one power point or running appliances that draw high amps at the same time. The result of an overload can be a short circuit and quite possibly a fire.

Answer:
If a mutation gives the bacterium an advantage in a particular environment, this bacterium will grow better than its neighbors and can increase in numbers – it is selected for.

Answer:
Simple diffusion do not show the property of specificity, competition, and saturation.
Facilitated diffusion shows properties of specificity, competition, and saturation.
Explanation:
Diffusion or simple diffusion may be defined as the process of movement of particles along the concentration gradient and an energy independent process. Facilitated diffusion occurs with the help of carrier protein.
Specificity is the ability to transfer the specific molecules only. Simple diffusion is not specific in nature while facilitated diffusion can transfer specific molecules only. Competition refers to the ability of transporter to transport the closely related molecules but the substrate must compete with each other. The simple diffusion do not have any competition in their molecules whereas the molecules of the facilitated diffusion must compete with each other. Saturation means the transport rate depends on the substrate and number of molecules. This property is common in facilitated diffusion and not in simple diffusion.
Thus, the answer is Simple diffusion do not show the property of specificity, competition, and saturation.
Facilitated diffusion shows properties of specificity, competition, and saturation.
Answer:
Darwin's discussion of bird species on the Galapagos islands relates to natural selection because the finches all have a recent common ancestor, but they evolved on different islands with different types of food, so the birds that weren't fit enough to survive the island conditions died, and the ones that did were "naturally selected."
Explanation:
The finches all have a recent common ancestor but they evolved on different islands where different types of food are available. During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants. Among those that struck Darwin so greatly were the finches that are now named in his honor.
Answer:
a) Most alcohol is metabolized in the small intestine.
b) Food in the stomach slows the absorption of alcohol.
c) Alcohol inhibits the release of anti diuretic hormone, which can lead to dehydration.
Explanation:
About 80 % of alcohol is absorbed by the stomach while 20 % of alcohol is absorbed by stomach. Food materials such as lipids etc slow down alcohol absorption by the intestine because the valve that is present between stomach and small intestine is closed if food is present in the stomach. Alcohol decreases the release of anti diuretic hormone, so low water is removed from the body and reduce dehydration.
