you are an astrobiologist (a biologist who studies other planets for signs of life). you have discovered a unique substance which is made up of four metals, organized in a specific and repeatable pattern. when exposed to electromagnetic radiation, this substance becomes bigger and can produce multiple copies of itself. if it is poked with a stick, it moves away from the stick. if the substance is kept in a dish for a while, rust accumulates in the dish.

classify this substance as living or nonliving, justify your answer.

This is a living substance since it can reproduce, forming copies of itself.

Explanation:

Although the substance shown in the question above shows many characteristics that can classify it as a non-living substance, it should be considered a living substance. This is because, as we can see, when exposed to electromagnetic radiation, this substance becomes larger and can produce several copies of itself. Forming copies of itself is a type of reproduction and only living substances can reproduce.

In addition, this substance has the ability to respond to stimuli, which is a characteristic of living substances and can be observed when the substance moves away from the stick.

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.
