In the distribution of scarce resources, caste systems rely on_____statuses and class systems rely on _____statuses.
a. achieved; ascribed.
b. normative; social.
c. educational; employment.
d. ascribed; achieved.

Answers

Answer:

In the distribution of scarce resources, caste systems rely on ascribed statuses and class systems rely on achieved statuses. (letter D)

For instance, you can be born poor but end up wealthy by gaining knowledge that will lead you to better job opportunities. Therefore, this type of system has social mobility.

Explain why an energy pyramid is used to represent the amount of energy at each
trophic level.

Answers

A pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.

The main reason why a pyramid is used to represent the amount of energy at each level is that energy is lost as one goes up the energy hierarchy.

The energy hierarchy is such:

Plants get energy from the sun and use it to make food Herbivores eat plants and get some of that energy Carnivores eat herbivores and get some of that energy Decomposers get energy when they decompose carnivores

The energy transfer from one level to the other is not efficient because up to 90% of energy is lost per level. For instance, the herbivores only get about 10% of the energy that the plants have.

In conclusion, the energy hierarchy is a pyramid to show that as one goes up the hierarchy, the energy acquired drops.

Answers

Answer:

The answer is C

Explanation:

The following groups had no clan system: Apaches. The Apache tribe did not have a traditional clan system. The correct option is b.

The Apache people were organized into extended family groups or bands rather than formal clans. These bands were often led by a chief or a respected leader, and individuals were primarily identified by their band affiliation rather than belonging to specific clans.

On the other hand, the Kiowas, Tonkawas, and Comanches, which were Native American tribes, did have clan systems as part of their social and kinship structures. Clans played a significant role in their cultural, social, and ceremonial practices, and individuals' identities and relationships were often tied to their respective clans within these tribes.

Thus, the ideal selection is option b.
