Answer: The process associated with RNA polymerase is to unwind the DNA and build a strand of mRNA by placing on the growing mRNA molecule the base complementary to that on the template strand of the DNA. In the mRNA, Uracil is substituted for thymine as the base complementary to adenine.
Explanation:

A food chain is the order in which we can see which predators eat which prey. Food chains are easier to understand at a glance then a food pyramid.
The spider has a venom in their teeth that they inject into your skin when they bite you so you won’t bleed everywhere and your skin has a reaction to the venom because it’s strong enough to have an effect just not strong enough to hurt you.
Explanation:
Atoms involved in covalent bonding do not separate into ions. Ionic and covalent bonds differ in the degree of sharing of the electron densities between them. Covalent bonds share the electrons more equally and are stronger. Ionic bonds share the electrons very unequally and can be broken into ions
