Dr. Hincapie recognized that the two larger pieces of DNA-
2100 base pairs and 1800 base pairs were from plasmids found
in bacteria that cause infections. The brightness of a piece of DNA
on a gel reveals two things: larger pieces of DNA are brighter
than smaller pieces and larger amounts of DNA appear brighter
than smaller amounts. Knowing this, which bands on this gel do
you think contain a gene for resistance to:

compost can be added to topsoil as a:

pesticide

supercell thunderstorms are perhaps the most violent of all thunderstorm types, and are capable of producing damaging winds, large hail, and weak-to-violent tornadoes

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.
