Which of the following is true of the energy levels of electrons in shells?
anyanavicka [17]

Answer:

Option C is the correct. Valence electrons have a higher energy level than those in other filled shells

Explanation:

Electrons must lose energy to move from the first to the second shell. FALSE

The electrons always win energy to move from the first to the second shell.

All the electrons in an atom have similar energy levels FALSE.

They are not neccesary similar. In hydrogen these are the level energy -13.6 eV , -3.4 eV , -1.51 eV , -85 eV  and -54 eV

Electrons do not have potential energy, just kinetic energy. FALSE

They have both.

Valencia electrons are the last electrons in the last layer. They have as much energy as possible and are responsible for forming bonds with other elements.

What is the role if mutations in genetic variation and the diversity of living things? Use human inheritance examples as evidenc
aliya0001 [1]

Explanation:

Mutations on DNA create genetic variation and diversity on which natural selection acts upon. Mutation can be advantageous, disadvantageous or neutral. Those mutations that confer advantage are preserved in the population while those that are DISadvantageous are weeded out. This occurs because advantageous traits that give a particular advantage to individuals in the environment, however slightest, give them an increased chance of survival and passing their genes to subsequent generations.

An example is mutation that causes sickle cell-shaped blood cells. Individuals with sickle cell blood are less likely to contract malaria. Therefore in an environment where malaria is endemic, the population will have a higher allele frequency for sickle cell alleles that populations in non-endemic areas.
