Answer:
The answer that best fits into this sentence would be "denied the opportunity to obtain"
Explanation:
This is because Melvin Tumin was a firm believer on social stratification. This is a system that classifies people into different groups that depend on their wealth, income, social status and derived power. This makes it extremely difficult for underprivileged kids to achieve their dreams of becoming successful in a certain profession because in order to get to that level they need certain resources and contacts that are only available to higher class groups.

Hello. This question is incomplete. The full question is:
"Technological improvements and reduced equipment costs have made converting solar energy directly into electricity far more cost-efficient in the last decade. However, the threshold of economic viability for solar power (that is, the price per barrel to which oil would have to rise in order for new solar power plants to be more economical than new oil-fired power plants) is unchanged at thirty-five dollars. Which of the following, if true, does most to help explain why the increased cost-efficiency of solar power has not decreased its threshold of economic viability?
(A) The cost of oil has fallen dramatically. (B) The reduction in the cost of solar-power equipment has occurred despite increased raw material costs for that equipment. (C) Technological changes have increased the efficiency of oil-fired power plants. (D) Most electricity is generated by coal-fired or nuclear, rather than oil-fired, power plants. (E) When the price of oil increases, reserves of oil not previously worth exploiting become economically viable."
Answer:
(C) Technological changes have increased the efficiency of oil-fired power plants.
Explanation:
Economic viability is able to reveal the degree of acceptance of consumers in relation to a specific product. This viability is important to understand how the product will be received in the market and how profitable or not it can be for those who produce it.
Economic viability is usually greater when the cost and benefit ratio of the product or service is favorable, however this is not always the case.
Regarding the use of solar energy, although technological changes have made the installation and equipment of this type of energy more cost-effective, these technological changes have also increased the efficiency of oil plants. As a result, the economic viability of solar energy has declined.
Answer:
Darwin's theory is based on four observations:
- Members of a population of the same species vary in their traits.
- Traits can be inherited, or passed from parents to offspring.
- Populations are capable of producing more offspring than the environment can support.
- Due to a lack of food or other resources, many of the offspring do not survive.
Natural selection will only occur if all these points can be observed and followed.
Explanation:
According to Darwin, organisms that are better adapted to the environment have greater chances of survival than those less adapted, leaving a greater number of descendants. The best adapted organisms are therefore selected for that environment.
There are three advantages and two disadvantages in collaboration.
<u>Explanation:</u>
- In the workplace, many people can work.
- They can share a lot of key ideas, new projects, and innovative approaches.
- So there are some advantages and disadvantages are present.
- They must overcome all the conflicts to the success of the project.
- First, the advantage is the way the work is divided.
- It depends upon the size of the project.
- Second, the advantage is a sense of creativity.
- It is used to know the visibility and quality of the products.
- Third, the advantage is increased employee morale.
- The two disadvantages are conflicts among workers and leadership among workers.
