Ionic compounds are formed between a cation, which is usually a metal, and an anion, which is usually a nonmetal. A covalent bond involves a pair of electrons being shared between atoms. I hope this helps you out.
Texture i think because that is the only way you can determine if anything is rough or not
Pain is more defined as a symptom
Both photosynthesis and respiration involve the conversion of energy from one form to another through a series of biochemical reactions. Both processes use and produce ATP in reactions that are carried out on membranes and are controlled by enzymes.
Photosynthetic organisms use the process of photosynthesis to produce their energy. During this process they also take in carbon dioxide and release oxygen. If there were less of such organisms, there would be more carbon dioxide and less oxygen in the atmosphere.
