<span>In cells, enzymes are proteins that are needed to lower the amount of energy required to start chemical.</span>
Enzymes are biological catalysts which accelerate chemical reactions (reactions are millions of times faster than without them). Every enzyme has an active site which binds substrates and converts them into products.
<span>Chemical bonds hold atoms
together to form compounds. The answer is letter D. Chemical bonds may result
through the sharing of electrons as in covalent bonds or from the electrostatic
force of attraction between atoms with opposite charges as in ionic bond. There
are other bonds that exist to other compounds such as metallic bond and
hydrogen bonding. Also, the type of bonding will help us determine what will be
the phase of the compound. Just like in liquids, attractive forces are caused by
van der Waals bonds.</span>
It is Choice B "by drinking water and other liquids"
<span>In a way, the process of primordial germ line isolation encourages / supports abortions. I feel that, those who choose to terminate their pregnancies under their own consent are going to do so regardless of how their undeveloped baby is going to be utilized after the face. The process of primordial germ line isolation merely utilizes what otherwise would be waste</span>
