Multicellular organisms are referred to as eukaryotes while the opposite, unicellular organisms, are called prokaryotes. Among all the kingdoms, I believe the kingdom which all organisms are multicellular are Animalia and Plantae.
The correct order of steps in a gram staining procedure is:
(4) the specimen is treated with a stain called crystal violet.
(1) iodine is added as a fixative or mordant.
(3) the specimen is flushed with alcohol to dehydrate peptidoglycans and trap the stain.
(2) the specimen is treated with a stain such as safranin or fuchsin (a pink stain)
Gram staining is a common staining technique which helps to classify the bacteria into two categories: Gram positive and Gram negative. Gram positive bacteria appear violet in color and Gram negative bacteria appear to be pink. This color difference appears due to the difference in the bacterial cell walls.

Answer:
C shrink
Explanation:
a hypertonic solution has more solutes than the intracellular environment, so water will leave the cell to try to achieve equilibrium. If enough water is lost, the cell will take on a wrinkled or shriveled appearance. In red blood cells this is called crenation and the surface of the cells take on a scalloped appearance. A high amount of water loss can be damaging or even fatal for a cell.
I need more context to answer. What are the statements?
Answer:
P generation: 1 purple flower (AA) : 1 white flower (aa)
F1 generation: 4 purple flowers (Aa) : 0 white flowers
F2 generation: 3 purple flowers (AA, Aa) : 1 white flower
Explanation:
Assuming the parents are AA and aa, the allele for white flowers is recessive, so there needs to be two of them for the trait to be expressed. Thus, the capital A purple allele that the other parent contributes will mask that white allele and all the flowers will appear purple. However, all of the offspring are Aa now, so when they are crossed, there's a 25% chance that they'll both contribute the lowercase a allele that codes for white flowers. Remember that if both of them give the lowercase a allele then the offspring will be aa and appear white.
