earth is just one of the planets that revolve around the sun in the solar system, and the sun is just one of billions of stars within the milky way galaxy. the milky way is one of thirty galaxies in a cluster of galaxies called the local group. the local group is just one cluster within a super-cluster called the virgo super-cluster. and finally the virgo super-cluster is just a tiny part of the entire universe.

galaxies are systems of stars, gases, and dust that exist in a wide variety of shapes and sizes. the simplest classification scheme devised by edwin hubble recognizes four basic types of galaxies; elliptical, spiral, barred spiral, and irregular. identify the shape of earth’s galaxy.

a) spiral

b) lenticular

c) elliptical

d) irregular
plz hurry i need this 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.

2%? i tried finding the exact sorry if it's not 100% correct ; -;

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
