The answer should be A capillaries
Answer:
Earth rotates on its axis; this causes us to experience day and night.
Explanation:
There is a time when Earth's north pole is tilting 23.5 degrees toward our Sun.
I really, really think it might be C. because they both can, only flat worms live in intestines and and roundworms have a pseudocoelom not a coelom. B also through me off because flat worms are symmetric.
That is an ionic bond.
Ionic bonds are the type of bonds where there is transfer of an electron from one atom to another. The electron is removed from one atom and attached to another.
An example is salt, which is composed of two elements namely sodium and chlorine. Sodium readily gives up one its electrons and chlorine readily accepts it. Before sodium loses the electron, it has a positive charge and after the electron is gone it becomes negatively charged.
Chlorine on the other hand is positively charged before accepting the electron but after it does so, it becomes negatively charged.
These opposite charges attract the two elements together to form a relatively strong ionic bond.
