Answer:
The most appropriate answer would be option C.
Nonrenewable resources are the natural resources which are present in a limited amount on the planet.
It is because the rate of their utilization is way too faster than the rate of their formation in nature.
Examples may include coal, gas, petroleum et ctera.
Gas stove utilizes the energy of liquified petroleum gas to heat or cook the food which is a nonrenewable resource.
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.
The number of the chromosomes in each of its body cells from the number of chromosomes of its gametes would be 9. It is because the number of chromosomes in a gamete must be halved in order to achieve the number of chromosomes present in each body cell which is important for cell division.
