Aparticular bird species found in north america obtains most of its food energy by catching and eating insects. a mutation arises in this bird population that increases the length of its beak. although many mutations are harmful, this particular mutation has increased the ability of the bird to catch and eat certain insects. which of these is the most likely outcome of this mutation?
a)the insects that are eaten by this bird are likely to become extinct. b)sharp pointed beaks will result in the birds eating other more unusual food items. c)other bird species will be more likely to also develop pointed beaks in order to compete. d)individual birds with the mutation will be more likely to survive and reproduce than birds without the mutation.

.D)Individual birds with the mutation will be more likely to survive and reproduce than birds without the mutation.

Natural selection is the differential survival and reproduction of the organisms that exhibit better phenotypic traits over the other organisms. Any particular mutation or adaptation which occurs in a species and allows it to survive in adverse conditions favors natural selection.

In the given situation, Individual birds with the mutation will be more likely to survive and reproduce than birds without the mutation is the relevant option as it favors the natural selection of the birds which have undergone with the mutation over the one which has not.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.

your answer should be c) enjoy!
