Explanation:
Because the lung has two bronchi, it can still function if one bronchus is blocked by a foreign object. No gas exchange will happen to the affected side, and the other lung will compensate for the loss of air. The blocked portion though can become inflamed and can lead to infection and damage.
Answer:
a. commensalism is the correct answer.
Explanation:
By growing on the trunk or branch of a tree, a lichen gains height and exposure to sunlight for photosynthesis. The tree is not harmed by the lichen but does not benefit either. The relationship between the lichen and the tree is commensalism.
Commensalism is a relationship between two organisms where one organism gets benefits from other organisms without causing any harm or any damage from the relation as it one side symbiotic relation.
In this, we can see lichen is getting benefits from the tree.
for example, lichen is getting following benefits from the tree such as ( a lichen gains height and exposure to sunlight for photosynthesis.) and they are causing any harm to tree neither any benefits so this is a one-side symbiotic relation and thus the relationship is an example of commensalism.
Answer:
All chemical reactions involve energy.Energy is used to break bonds inreactants, and energy is released when new bonds form in products. Endothermic reactions absorb energy, and exothermic reactions releaseenergy. The law of conservation ofenergy states that matter cannot be created or destroyed.
