Answer:
They are microorganisms that are important in the nitrogen cycle as converters of soil ammonia to nitrates, compounds usable by plants.
Explanation:
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.

Answer:
hello your question lacks the required option below are the missing options
A) The gene for insulin is a sequence of five different molecular bases while the gene for testosterone is a sequence of only four different molecular bases.
B) The gene for insulin is replicated in vacuoles, while the gene for testosterone is replicated in mitochondria
C) The gene for insulin has a different sequence of molecular bases than the gene for testosterone.
D) The gene for insulin is turned ON in liver cells, but the gene for testosterone is not
answer : The gene for insulin has a different sequence of molecular bases than the gene for testosterone ( C )
Explanation:
The statement that indicates the difference between the gene that codes for insulin and a gene that codes for testosterone is ; The gene for insulin has a different sequence of molecular bases than the gene for testosterone.
Genetic codes are determined basically by the four types of nitrogen bases contained in the molecules of the DNA ,
Photosynthesis and cellular respiration are<u> chemical reactions</u> that occur in cells.
<h3>What is photosynthesis and cellular respiration?</h3>
Photosynthesis is the process of making food through carbon dioxide, water and sunlight. It is an anabolic reaction.
Cellular respiration is the process of breaking down of food molecules by oxygen. It is a catabolic reaction.
Thus, the correct option is a, chemical reaction
