C. At some point, the land masses were connected to each other.
Explanation:
The fossils now exists far away from each other because at some point, the land masses were once connected to each other. Now, the land masses have drifted apart due to plate tectonics.
Alfred Wegener a scientist in 1912 first formulated the theory of continental drift. The theory suggests that present day land masses have moved to their present positions.
- A more refined theory of plate tectonics is now in play today and it provides a better understanding to why we can find similar features across different continents.
- The similar fossils must have formed together when the land masses were once joined together.
- Noe that the land masses are separated, the fossils species are not separated.

Answer:
covalent bonding, hydrogen bonding
Explanation:
<u>The molecular formula of water is
in which the two hydrogen atoms are connected to the oxygen atom via covalent bonds which means that the electrons are shared in the bond.</u>
Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.
Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.
<u>Thus, when multiple water molecules are there, there are connected by hydrogen bonding.</u>
A. phase changing. Physical change is any change in matter that involves the substance going from one physical state to another, and phase change is most commonly used to describe transitions between solid, liquid and gaseous states of matter.
Imagine A is a Heterogeneous mixture because it a mixture composition that does not stay the same throughout the mixture.
Imagine B is the Homogeneous mixture because it has no changes or irregularities
First one because Common synthetic materials are nylon, acrylic, polyester, carbon fiber, rayon and spandex. Synthetic materials are made from chemicals and are usually based on polymers. They are stronger than natural and regenerated materials.
