The answer is copper. Nonrenewable resources are those that cannot be readily/naturally replaced at rates that match those of consumption (an aspect that allow renewable resources to be sustainable). Copper are made deep in earth at very slow rates hence do not readily renew themselves. Organisms, on the other hand die, and are naturally replaced by offspring.
Due to the need to have completely controlled experiments to test a hypothesis, science can not prove everything. For example, the scientific method cannot alone say that global warming is bad or harmful to the world, as it can only study the objective causes and consequences.
Answer:
Hydropower does not pollute the water or the air. However, hydropower facilities can have large environmental impacts by changing the environment and affecting land use, homes, and natural habitats in the dam area.
Answer:
t describes Linus Pauling's contribution to the understanding of DNA structure?
Having first discovered the spiral shape of proteins, Linus Pauling used x-ray technology to hypothesize that the DNA molecule consisted of two consistently spaced strands that formed a spiral shape.
Linus Pauling studied DNA base pairing.
Having originally studied proteins, Pauling proposed that DNA was a three-chained helix with a sugar-phosphate backbone at the center and bases sticking out from the backbone.
Linus Pauling conducted experiments to prove that DNA carried genetic information.
Explanation:
Answer:
Fungi are described as decomposers in most food webs. The typical fungus secretes digestive enzymes from its body that breaks down dead organic matter into inorganic nutrient. Without these decomposers (bacteria and fungi) carbon, nitrogen, and other elements would remain tied up in organic matter.
<h2>What are decomposers?</h2>
An organism, usually a bacterium or fungus, that breaks down the cells of dead plants and animals into simpler substances.
Fungus are any of a diverse group of eukaryotic single-celled or multinucleate organisms that live by decomposing and absorbing the organic material in which they grow, comprising the mushrooms, molds, mildews, smuts, rusts, and yeasts, and classified in the kingdom of Fungi or, in some classification systems, in the division Fungi (Thallophyta) of the kingdom Plantae.
