Answer:
"The Mississippian Period lasted from approximately 800 to 1540 CE. It’s called “Mississippian” because it began in the middle Mississippi River valley, between St. Louis and Vicksburg. However, there were other Mississippians as the culture spread across modern-day US. There were large Mississippian centers in Missouri, Ohio, and Oklahoma."
Explanation:
"The construction of large, truncated earthwork pyramid mounds, or platform mounds. Such mounds were usually square, rectangular, or occasionally circular. Structures (domestic houses, temples, burial buildings, or other) were usually constructed atop such mounds.
Maize-based agriculture. In most places, the development of Mississippian culture coincided with adoption of comparatively large-scale, intensive maize agriculture, which supported larger populations and craft specialization.
The adoption and use of riverine (or more rarely marine) shells as tempering agents in their shell tempered pottery.
Widespread trade networks extending as far west as the Rockies, north to the Great Lakes, south to the Gulf of Mexico, and east to the Atlantic Ocean."
Answer:
1. Bats and cats: <em>Homology</em>
2. Whales and sharks: <em>Analogy</em>
Explanation:
In Biology, homology refers to <u>the similarity of features from different species of organisms that share a common ancestor</u>. This is the opposite of analogy, which refers to <u>a feature that has a similar function but is not derived from a common ancestor</u>.
In this case, bats and cats have forelimbs adapted for locomotion. This is a case of homologous characters because they both are descendants of tetrapods - four-limbed animals. Therefore, even though cats and bats look completely different, they both share a similar feature: forelimbs, a characteristic feature from their common early mammalian ancestors.
On the other hand, whales (mammals) and sharks (fish) do not share a common ancestor. So, the fins are analogous structures: both have a similar function because both have adapted to an aquatic environment but they have completely separate evolutionary origins.
Answer:
True.
Explanation:
A progressive tax is a tax that imposes a lower tax rate on low-income earners compared to those with a higher income, making it based on the taxpayer's ability to pay. That means it takes a larger percentage from high-income earners than it does from low-income individuals.
