describe the difference between covalent and ionic bonds. give one example of each
Answer:
Actually, a covalent bond is formed between two non-metals. Electrons are shared between the two atoms in order for them to achieve a full outer shell. Covalent compounds do not conduct electricity. An ionic bond is formed between a mental and a non-metal. Electrons are transferred from the metal atoms to the non-mental atoms to form ions. Ionic compounds conduct electricity when dissolved.

What is the relationship between natural selection and population?Natural selection can cause microevolution (change in allele frequency), which causes fitness-enhancing alleles to become more common in the population. Fitness is a measure of reproductive success (how many offspring an organism leaves for the next generation, relative to others in the group).
Another factor that limits the growth of populations is densification. This means that a large number of individuals present at the same time in the same area reduces the availability of resources for the population as a whole, increasing the mortality rate and reducing reproductive success.
