After crystal violet staining, the Gram-positive bacteria may appear dark blue or violet. The cell wall of gram positive bacteria have thick peptidoglycan layer, thus it retains the crystal violet stain compared to gram negative bacteria.
Hope this helps! Have a good day!
During binary fission in a bacterial cell, a base pair is changed from adenine to cytosine due to a random mutation.
Binary fission is a type of asexual reproduction through which a bacteria divides and its body is separated into two new bodies.
If during binary fission in a bacterial cell, a base pair is changed from adenine to cytosine, it is because of a random mutation. A mutation is a genetic alteration or a change in the DNA sequence which results in the generation of a variant. Mutations in the DNA sequence which occur without any specific pattern is known as a random mutation.

Answer:
incompletely dominent
Explanation:
because hetrozygouse like Hh is incompletely dominent. but it's dominent means it expresses the dominent allele H
Explanation:
1. cell membranes are partialy permeable, only allowing passage to some certain molecules.
2. diffusion is the movement of molecules across partially permeable membrane down concentration gradient.
3. the molecules are too big to pass through partially permeable membrane. the concentration of the molecule might be higher in the cell than in the solution/surroundings.
