The star Aldebaran is an orange giant star in the constellation Taurus, the bull. Aldebaran
is the eye of the bull, and is about 65 light
years away. What would happen if
Aldebaran were to explode tonight?
(F) We would see the explosion before
we hear it.
(G)We would see the explosion right
away.
(H) We would see the explosion in
65 years.
(I)We would never be able to see the
explosion

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.

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
