Answer:
if you are not using alcohol (95% ethanol), you are not decolorizing the wall of the gram-negative bacteria, which should get rid of the violet color, therefore the safranin stain, in the next step, won't be absorbed in the wall, and the bacteria will end up being purple due to the previous crystal violet stain of the gram-positive bacteria

Answer:
Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things. All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.
Answer:
Incomplete dorminance.
Explanation:
Incomplete dorminance occurs when two heterozygous alleles are expressed together which is as a result of dorminant alleles not completely masking the recessive alleles and the two alleles blend together and are expressed phenotypically.
The above question is incomplete dorminance because the allele for tallness in the sheep does not completely mask the allele for shortness and these two alleles blend together to produce intermediate progeny that are expressed phenotypically.
A sperm joins an egg cell in the process of fertilization. Because first both of the parents must contribute one gamete, then the sperm and egg unite in the process called fertilization, and finally this process forms a single celled structure called a zygote which contains the full genetic information that will be passed to the offspring. And now the offspring will have half of it's genetics from both of it's parents.
I know all of this because I just learned, studied, and took a test on this topic. Plus I checked Google just to make sure I was correct. Hope I helped you!

Grassland soils are very fertile and nutrient-rich because of the growth and decay of deep grass roots. The rotted roots provide a food source for living plants.
