<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>
Answer:
The answer is only about 40
Explanation:
Whenever something is consumed, only about 10% of the energy is consumed. So when a primary consumer eats the producer, they will get about 4,000 kcal. Then the secondary consumer will get about 400. Finally, the tertiary consumer will only get about 40. Basically, just multiple the original number by 0.1 for every time it goes through consumption.
Answer:
The fungicide destroys mycorrhizal symbionts.
Explanation:
Mycorrhizal symbionts is the symbiotic association that is present between plants and fungi. Plants provide food materials in the form of sugar to the fungi while fungi fixes phosphorus for the plant that is present in the soil in unavailable form. When fungicide is sprayed, it kills the fungi present in the soil and deficiency of phosphorus occurs in plants.
B. The tick is a vector. Vectors are like vehicles that carry genetic material. The tick is carrying the genetic material of lyme disease to the animal.
