Competitive exclusion is based on the idea that Select one: a. all of these b. one species will hold some sort of advantage over the other one c. no two species can completely occupy the same niche d. the more two species overlap in their capacity to obtain and use resources, the less likely they are to coexist

Option A.

All of these.

Explanation:

Competitive exclusion state that or show that two organisms who compete for the same resource in the same habitat cannot occupy the same niche and cannot coexist because the stronger organism or superior one tend to outcompete the weaker organism thereby leading to the exclusion of the the weaker organisms. It is a principle in ecology also called Gause's law.

the answer is b.) hydrogen bonds between bases.

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
