When species are extensively hunted, individuals that reach reproductive maturity early make up a larger proportion of the population, because they have a better chance of reproducing. when species face diminished food resources, on the other hand, individuals tend to take longer to reach reproductive maturity. these considerations may settle whether the primary cause of the gradual disappearance of north america's mastodons, prehistoric animals related to elephants, was diminished food resources or human hunting, since
(a) from the location of certain hunting weapons in juxtaposition with mastodon remains, it is possible to determine whether those weapons were used to hunt mastodons.
(b) the average age at which mastodons reached reproductive maturity can be established from mastodon tusks, of which there are many fossils dating from different periods
(c) from the remains of mastodons already discovered, it can be accurately estimated when mastodons became extinct
(d) from tusks and other bones, it is possible to determine whether male and female mastodons reached reproductive maturity at about same age
(e) it is possible to determine whether earliest human dwellings constructed from mastodon tusks and bones come from an earlier period than the earliest hunting weapons unambiguously associated with mastodon remains.

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.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.

2%? i tried finding the exact sorry if it's not 100% correct ; -;

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.
