The correct answer will be option- evolution of photosynthesis, first eukaryotic cells, first animals, Cambrian explosion, first land plants.

Explanation:

The origin and evolution of life started around 3.8 billion years ago. After this period life evolved and diversified adapting in the environment. The evolution of life is arranged on a geological time scale in chronological order on the basis of paleontological studies.

The studies have revealed that bacteria became photosynthetic utilizing the carbon dioxide and sunlight to make food around 2.15 billion years ago. After the evolution of photosynthetic bacteria, cells with well-defined organism came into being around 2 billion years ago which formed an endosymbiotic relationship and formed multicellular organisms. this multicellular organism formed the first simple animals around 900 million years ago in water. Around 543 million years ago the Cambrian explosion took place after which first land animals and plants appeared around 465 million years ago.

Thus, the selected option is the correct answer.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
