Answer:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. ... In addition, several enzymes of the light-independent reactions are activated by light.
Answer: In the wetland, nitrates are absorbed by plants or converted (through an anaerobic process called denitrification) to nitrogen gas and lost to the atmosphere. Nitrate-N is efficiently removed from wetland surface waters by aquatic plants. Ammonium-N enters wetlands primarily through surface runoff.
Nitrogen pollution in wetlands is processed through the nitrogen cycle involving ammonification, nitrification, and denitrification, conducted by various bacteria and fungi. These processes recycle nitrogenous waste and send it back to the atmosphere, the ocean floor, or the terrestrial food web as organic nitrogen.
Nitrogen pollution, resultant from human activities like burning of fossil fuels and use of artificial fertilizers, can be processed by wetlands through a biological process known as the nitrogen cycle. The cycle involves three steps: ammonification, nitrification, and denitrification. In the ammonification process, nitrogenous waste is converted into ammonia (NH3) by bacteria and fungi. This ammonia is then oxidized to nitrite (NO₂), and then to nitrate (NO3) in the nitrification process by soil bacteria such as Nitrosomonas. Finally, in the process of denitrification, soil bacteria like Pseudomonas and Clostridium, convert nitrate into nitrogen gas that reenters the atmosphere. Some of this nitrogen also settles into the ocean floor as sediment and becomes incorporated into terrestrial rock. Nitrogen thus processed by the wetland becomes the organic nitrogen required by the terrestrial food web.

Answer:
An earthquake
Explanation:

C. metamorphic
D. igneous
Answer:
( A). sedimentary is a correct answer.
Explanation:
Fossils are the impression or remains of plant and animal present on the layer of sedimentary rocks.
Fossils are usually found in sedimentary rocks, as these rocks are formed on the Earth's surface at low pressure and temperature.
The sedimentary rock contains fossil, as they are formed at low temperature and pressure, due to this fossil remains, are not destroyed.
Thus this the reason Fossils are usually found in sedimentary rock.
Fossils are usually found in sedimetary rock. The correct option is A.
Thus, Sedimentary rocks are typically where fossils are found. Sediments, which may contain animal and plant remains, build up and cement together to produce sedimentary rocks.
These sediments may get lithified over time and solidify into sedimentary rock.
Because the layers of sediment can shield and preserve the remnants of ancient species, fossils are frequently preserved in sedimentary rock, offering important insights into Earth's past and the evolution of life on our planet.
Thus, Fossils are usually found in sedimetary rock. The correct option is A.

Answer:
Cancer.
Explanation:
Genetically engineered organism (GMOs) may be defined as the organisms whose genetic material has been modified by using the molecular techniques. Animals, plant, bacteria and viruses can be used as GMOs.
The genetically modified hormones in the dairy product is bovine. The bovine hormone helps in increasing the lactation and milk production in cattles. The bovine hormone is responsible for the differentiation and growth of the abnormal cells as well. The process of apoptosis is inhibited by the bovine. This might result in the formation of cancer.
Thus, the correct answer is option (2).
