<span>When used in glaucoma, this drug blocks beta-1 and beta-2 adrenergic receptors resulting in decreased aqueous humor production: Timolol
Beta blocker is common medication in glaucoma, but many beta blocker is selective to beta-1 or beta-2. Nonselective beta blocker would be timolol.</span>

Trees are a crucial part of the<span> carbon cycle</span>, a global process in which carbon dioxide constantly circulates through the atmosphere into organism and back again. Carbon is the second most valuable element to life, you know, after water. Anyway, trees take carbon from the atmosphere through <span>photosynthesis </span>in order to make energy. This carbon is then either transferred into oxygen and released into the air by <span>respiration </span>or is stored inside the trees until they decompose into the soil. Therefore, the absence of trees would result in significantly HIGHER amounts of carbon dioxide in the air and LOWER amounts of oxygen! The filthy air would also be full of airborne particles andpollutants like carbon monoxide, sulfur dioxide and nitrogen dioxide and its temperature may increase by up to 12 F.
Conserve hot water.. check on the heating system and the water heater..
Ans. (A).one species would be force to leave.
A niche is defined as a specific area, where an organism lives and interacts with all the abiotic and biotic factors that affect it.
Two organisms cannot survive in the exactly same habitat as they will compete for same resources, so one will die). Hence, one of the two competing species gets evolved to use a different niche and uses different sources. This is known as resources partitioning and helps the organisms to coexist by reducing competition between them.
Thus, the correct answer is option (A).
