Answer:
In most trees, the area just under the bark layer contains moisture in the form of sap and water. And since water is a better electrical conductor than wood, lightning striking a tree tends to travel just underneath the bark.
The answer is D, for when one tropic level is eaten by the tropic level above it, the tropic level is supporting the higher one. I. E. Rabbits are supported by the grass because rabbits eat the grass. Also, the grass population would be larger than rabbits, the rabbits larger than snakes, so on and so forth, so B is ruled out. B states that each population is larger than the one BEFORE it, but there is no way there would be more rabbits than grass. Also, there are both herbivores and carnivores in the food chain, so A and C are out. The best answer is D.
<span>The chemical elements</span><span> can be broadly divided into </span>metals<span>, </span>metalloids<span> and </span>nonmetals<span> according to their shared </span>physical<span> and </span>chemical properties<span>. All metals have a shiny appearance (at least when freshly polished); are good conductors of heat and electricity; form </span>alloys<span> with other metals; and have at least one </span>basic oxide<span>. Metalloids are metallic-looking brittle solids that are either </span>semiconductors<span> or exist in semiconducting forms, and have </span>amphoteric<span> or weakly </span>acidic oxides<span>. Typical nonmetals have a dull, coloured or colourless appearance; are </span>brittle<span> when solid; are poor conductors of heat and electricity; and have acidic oxides. Most or some elements in each category share a range of other properties; a few elements have properties that are either anomalous given their category, or otherwise extraordinary.</span>
A type of commensalism is the sea anemone and the clown fish. The definition of commensalism is where another species lives within another. (Usually this relationship is with animals, fungi, and plants.) No harm comes to either species.
A clown fish lives in a sea anemone, and this doesn't hurt the anemone nor is the clownfish affected by its sting because of their oils that protect them.
If you didn't know, Nemo and his father, Marlin, lives in a sea anemone. A natural habitat of a clown fish.
