se cruzan 2 líneas de arvejas, una con las flores color púrpura y la otra con las flores blancas. Se obtuvo la primera generación y todos los individuos obtenidos fueron con flores púrpura. Después se cruzaron entre sí los individuos de la F1 y se obtuvieron 100 individuos en la F2. ¿Cuántos individuos de la segunda generación produjeron flores púrpura y cuántos individuos flores blancas.

the correct answer is:

a population changes in response to a change in the environment.

explanation:

okay now i don't know this but for the pints nothing else to say bye

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.
