Answer:
The correct answer is a. resource partitioning
Explanation:
Resource partitioning is a strategy that species employ to avoid competition. It is based on the selection of different nutrition sources by different organisms that coexist in the same ecological niche, so there is no conflict between them. In the present case, each one of the eight species of woodpeckers feed on different trees, it means that each one select a different tree´s species or, if they select the same species, they use trees of different diameters.
Answer:
Semicircular canals
Explanation:
Ear is one of the important sense organ responsible for hearing and equilibrium. Human ear is divided into three parts: outer ear, middle ear and inner ear.
Inner ear is mainly responsible for the equilibrium of the body. Vestibular apparatus together with semicircular canals is responsible for the dynamic equilibrium of the body. Dynamic equilibrium involves head rotation and vertical movements of the body.
Thus, the correct answer is option (a).

The right answer is The number of adenine will be equal to the number of thymine.
Chargaff's rules indicate that the DNA of any cell or organism must have a ratio of 1 to 1 between purine bases and pyrimidine bases and, more specifically, that the amount of guanine is equal to the amount cytosine, and that the amount of adenine is equal to the amount of thymine. This trend is found in both strands of DNA.
