The characteristic that makes viruses different than bacteria is viruses need to eat almost constantly in order to remain alive. The only function viruses need to do is to reproduce and in order to do it, they need to eat constantly. In contrast to it, bacteria do not need to eat constantly in order to survive. Viruses are not a full fledged cell. The only structures they have is a protein coat wrapped up around their genetic material i.e. their DNA/RNA. The protein coat around their genetic material is known as capsid.
Plants make their own food by photosynthesis. During photosynthesis a plant takes in water, carbon dioxide and light energy, and gives out glucose and oxygen.
Si el átomo contiene electrones que son partículas con carga eléctrica negativa, ¿por qué el átomo no tiene carga eléctrica neta? A. Porque la carga de los electrones de un átomo se equilibra con la de los electrones de los átomos vecinos.
