Among the given choices, the only positive effect that may be thought off with the increase in level of CO2 in the atmosphere is the increase of plant growth. Carbon dioxide is an essential compound in the photosynthesis of plants. Therefore, the answer should be letter C.
answer: proterozoic eon
Explanation: they found an abundant amount of fossils around 1.8 billion years ago, this would be called the proterozoic eon
Sugar beet
Sugar beet is a plant whose root contains a high concentration of sucrose and which is grown commercially for sugar production. In plant breeding it is known as the Altissima cultivar group of the common beet (Beta vulgaris).[1] Together with other beet cultivars, such as beetroot and chard, it belongs to the subspecies Beta vulgaris subsp. vulgaris. Its closest wild relative is the Sea beet (Beta vulgaris subsp. maritima) I hope this is maybe helpful
I believe the answer would be B.
Continents can be made to fit together like a piece of jigsaw puzzle, also the similarity of the Atlantic coastlines of Africa and south America was also recognized so Alfred wegener in the early 1900s made a strong case for continental drift , he noted that south America, Africa,India , Antarctica, and Australia had almost identical Paleozoic rock and fossils. He then reassembled the continent to form a giant super continent which he called pangea , his reason was that the similar rocks and fossils were easier explained if the continent are joined together.
Explanation:The fossil record helped to support the idea of pangea becos these fossils were found in all 5 continent as at that time so it could only be possible if these continent were actually joined together for example the fossil remains of land-dwelling reptiles Lystrosaurus and Cynognathus are found in Triassic-age rocks on all the five continent, also the plant Glossopteris is found in Pennsylvania and Permian-age rock on all five continent
