Species evolve at different rates. for example, bacteria are unlikely to become extinct because they adapt more quickly than mammals to environmental changes. which pf the following best explains this difference A: Bacteria reproduce more rapidly, allowing species to evolve more quickly

B:Bacterial populations are more isolated, permitting increases in genetic variability

C:certain bacteria grow more steadily over time, giving an evolutionary advantage over mammals

D: Individual bacteria have the same genes, providing opportunities for increased biodiversity in one population.

A

Explanation:

pure substance: iron,copper

impure substance: water,charcoal

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
