Fossils of ancient polar plants are currently found near the equator because the ________. A. entire earth had polar conditions
professor190 [17]
<h2>Answer is option "B"</h2>

Explanation:

  • Fossils are formed by unusal ways of minerals,energy and other substances. the sap solidifies and frames the semiprecious material called golden. In certain bits of golden the buried survives from living beings can be found. Volcanic ejections can shape fossils when creatures get caught in the hot debris streams. Right now, the fossil is a hole looking like an animal.
  • Truth be told coal is the fossil record of entire timberlands; in any case, singular plant structures normally don't make due as the plant materials are compacted to short of what one-hundredth of their unique size. the hard part of plants are remain the fossil.
  • So as to get fossilized, creatures must kick the bucket in a watery situation and become covered in the mud and residue.
  • hence, the right answer is option B "Plant lived near the poles,but landmasses have drifted to current locations".

After performing a gram stain of a mixed culture of gram positive and gram negative cells, you shout: "oops, i forgot the iodine
zalisa [80]

Gram's staining is a differential staining technique that employs a primary stain like crystal violet and a counter stain like safranin along with the decolourizing agent alcohol and a mordant called the Gram's iodine.

Iodine is a mordant added after the primary stain. It fixes the stain by combining with it to enchance the staining ability. This forms an insoluble crystal violet iodine complex appearing purple under the microscope. These microorganisms are classified as Gram positive.

If addition of iodine is skipped, crystal violet is not fixed on the slide and the insoluble complex is not formed. The cells are decolourized by alcohol and are stained by the counter stain safranin making the Gram positive cells wrongly indentified as Gram negative due to its pink colouration. Thus, the slide will show all the cells as pink coloured Gram negative cells.
