How do you stain drosophila chromosomes? Drosophila are the common fruit fly. Please be as descriptive as possible, but don't copy from a website lol. I'm not asking you to write an essay, but the more descriptive you are, the better.
***If you write a fake response, I'll report you***

option a and d is the correct answer

i hope this u

plz mark as the brainliest answer

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

the answer you are looking for is the united states forest service.

hope this !
