  • <em>Minerals containing a useful substance are referred to as ores. </em>
  • Ores are basically minerals with elements that are economically important to us and thus, the ores are mined to extract the useful substances.
  • More commonly the important elements extracted from these ores are the metals such as copper, iron, lead, zinc, and nickel.
  • The metals can either be present in the ores as oxides, silicates, sulphides or in their native state.

List four ways in which members of the same species can cooperate with each other.
ArbitrLikvidat [17]
Cooperation is common in non-human animals. Besides cooperation with an immediate benefit for both actors, this behavior appears to occur mostly between relatives.[1] Spending time and resources assisting a related individual may at first seem destructive to the organism’s chances of survival but is actually beneficial over the long-term. Since relatives share part of their genetic make-up, enhancing each other’s chances of survival may actually increase the likelihood that the helper’s genetic traits will be passed on to future generations.[6] The cooperative pulling paradigm is an experimental design used to assess if and under which conditions animals cooperate. It involves two or more animals pulling rewards towards themselves via an apparatus they can not successfully operate alone.[7]

if we use a cscl gradient to test the density of various nucleic acids, both rna and dna-rna hybrids are more density than just
Wewaii [24]

RNA and DNA-RNA hybrids are more dense than simply DNA if the density of different nucleic acids is tested using a CsCl gradient.

The primary technique employed in molecular biology is the extraction of DNA, RNA, and protein. Scientists can separate materials according to size, shape, and density by using density gradient centrifugation. Isopycnic centrifugation, a sort of density gradient centrifugation that Meselson and Stahl developed, employed a cesium chloride solution to separate DNA molecules solely on the basis of density. Because DNA has hydrogen bonds between its strands, which makes it less dense than RNA, RNA has a far larger density than DNA. RNA can be obtained at the test tube's bottom using a CsCl density gradient and high centrifugation, whereas DNA can be recovered in the middle layer.
