The quicker the regulation, the less energy and material wasted to unneeded products and pathways.
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:
u have it correct
Explanation:
it is D bc The organism in a stage between zygote to fetus is called an embryo* and the cells are called embryonic stem cells. At this point embryonic stem cells have the ability to become a cell for any part of the body (nerve, muscle, blood, etc.). This ability to become any type of cell in the body is called pluripotent.
The amino acids would change resulting in totally different proteins which is also called a frameshift mutation.
Answer:
d. 3/8
Explanation:
Black coat color (B) is dominant over red coat color (b) and solid color (S) is dominant over spotted color (b).
BbSs was crossed with Bbss
BbSs x Bbss
Offspring:
<em>2 BBSs black, solid</em>
<em>2 BBss black, spotted</em>
<em>4 BbSs black solid</em>
<em>4 Bbss black, spotted</em>
<em>2 bbSs red, solid</em>
<em>2 bbss red spotted</em>
Total black solid = 6
Hence, the chance that black solid individual would be produced = 6/16 = 3/8.
The correct option is d.
