Answer: D) 60/11 Explanation: A can complete the work in 12 days working 8 hours a day => Number of hours A can complete the work = 12×8 = 96 hours  => Work done by A in 1 hour = 1/96   B can complete the work in 8 days working 10 hours a day => Number of hours B can complete the work = 8×10 = 80 hours  => Work done by B in 1 hour = 1/80   Work done by A and B in 1 hour = 1/96 + 1/80 = 11/480  => A and B can complete the work in 480/11 hours   A and B works 8 hours a day. Hence total days to complete the work with A and B working together  = (480/11)/ (8) = 60/11 days

In the process of photosynthesis, plants need the sun's energy, water to make food for themselves in the form of ATP ( adenosine triphosphate ) , which is packages of energy. Carbon : coming into the plants ( or algae ) along with water make those ATP into a bigger molecule, which is know as glucose. Formula: 6 CO2 + 6 H2O + Suns Energy -> glucose + oxygen Photosynthesis has an affect on the carbon cycle because it reduces the amount of CO2 in the air and redirects it into sugars which feeds animals as well as humans.   Hence, Photosynthesis removes CO2 from the atmosphere and replaces it with O2.

Answer: B) Water Explanation: Abiotic and biotic factors are what make up an ecosystem.   Abiotic factors are all nonliving components of an ecosystem. These factors include chemical and geological features such as water or lack of water, soil, rocks, and minerals. Other abiotic factors include physical components such as the temperature and weather affecting the ecosystem. The biotic factors in an ecosystem include all living things. All plants, animals, fungi, protists, and bacteria within an ecosystem make up that system's biotic factors. The biotic factors can be broken down further into producers, consumers, and decomposers. The biotic factors present in an ecosystem are highly dependent on the abiotic factors that are present. Even slight changes to either factor can have a major consequence upon the system as a whole.
