A particular bird species found in North America obtains most of its food energy by catching and eating insects. A mutation aris
es 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 are more likely to survive & reproduce than birds without the mutations.
This is because the mutation is increasing their ability to catch and eat insects, thus increasing their chances of survival. Due to natural selection, birds with this mutation are favored because of their environment and they will most likely survive.
The correct answer is B. reduced amounts of small acid-soluble proteins.
Explanation:
Spores of Bacillus subtilis contains very small amount of small acid-soluble proteins which only comprise of 20% of the total spore core protein. These small acid-soluble proteins provides resistance against chemicals, heat or UV radiation.
