Answer:
c. Adaptive radiation occurs in the presence of competitors.
Explanation:
Adaptive radiation is a process of diversification in which new species are originated from an ancestral species due to changes in the enviroment or deu to pressures such as competition for resources that lead organisms to find new niches. For example, if there are many competitors for the same food source, that pressure could lead some organisms to look for a new food source, that, in turn, can lead to the adaptation of their body to the new food source. For example, bird beaks that were specialized for seeds can be adapted for insects.

Answer:
The correct answer will be option-thick bundles of fibers that allow communication between the brain’s hemispheres.
Explanation:
Cerebral commissures are the thick fiber tract composed of white matter which connects the same cortical areas of the left and right hemispheres of the brain.
Commissural fibers include many types of fibers in which corpus callosum fibers are one of the types of fibers which act as the main Cerebral commissures.
Since these fibers connect the two hemispheres, therefore, they help in the communication between two hemispheres.
Thus, the selected option is the correct answer.
Answer:
similarities
Explanation:
The concept of reproductive isolation relates more toward genetic similarities to distinguish between species. The barriers prevent closely related species living in the same geographical area from interbreeding. They help to keep each species distinct from the others.
