Answer:
The correct answer would be -
If the type of food available changes, then the frequency of beak also changes because the beak of the bird suited to food will survive successfully.
Explanation:
According to the theory of natural selection, an organism that is able to adapt according to the change in the environment, it helps in their survival and increases their number in the system.
It is given that the type of food available is changing, so it will lead to the change in the frequency of bird beaks in that particular area. So, if they adapt to survive under the changes in the available food type, otherwise not be able to survive and die.
So,
If the type of food available changes, then the frequency of beak also changes because the beak of the bird suited to food will survive successfully.

If it is an animal like an eagle or one who preys on other animals it is a Carnivore, if it is an animal such as a cow or mouse it is herbivore, if it is a mushroom or other fungus it is decomposer, and if it is a plant like a tree or flower it is a producer.
Answer:
A. Helicases
B. Single strand binding proteins
C. Single strand binding protein
D. Topoisomerases
Explanation:
The helicases bind on the replication fork aiding in the unwounding of the DNA helix to allow for replication. The single strange binding proteins attach/bind to the separated single stranded DNA after the replication fork to prevent re-annealing of the single stranded DNA preventing Hydrogen bond formation that reanneals these two strands together. The topoisomerases are found just ahead of the replication fork preventing overwounding/ positive supercoils of the DNA. They do this by introducing breaks into the phosphate backbone of the DNA allowing them rotate forming negative supercoils and attaching the breaks once the DNA strand is relaxed.
