Answer:
C
Explanation:
There is a tendency among the rich that whatever they have they deserve it and those who don't possess wealth are destined to be so. Rich people never like to be poor; they do often think the poor should be like that. How can everyone be rich? If so, who will do the sundry works? More so, rich people believe they are rich because of their hard work aided with luck while the poor are poor because they don't work hard and are unlucky enough not to possess wealth. Between the rich and the poor, there emerges prejudice and jealousy; while the poor are jealous to see wealthy people and their luxury the rich carry prejudice against the poor. Who wants another lion in the den? Carrying this notion the rich nurse grudge and ill-opinion against the poor. At the same, the rich justify their fortune since it favors the brave and the poor are not brave.
Answer:
Ok
Explanation: Living things adapt to their biotic environment to survive. Mammals in cold places need thick fur to stay warm. Reptiles sit on hot rocks in their environment to warm their bodies.
One of the most critical interactions in an ecosystem between the biotic and abiotic environment is photosynthesis, the base chemical reaction that drives most life on earth. Plants and algae use sunlight, water and carbon dioxide to create the energy they need to grow and live via photosynthesis. An important by-product of photosynthesis is oxygen, which animals need to breathe.
Interactions:
Red fox (Vulpes vulpes) and hare (Lepus europaeus) interactions are an excellent example of predator-prey dynamics. The hares consume grasses, then the red foxes predate the hares. The grasses are negatively impacted by the hares while the hares benefit by getting a meal. Foxes then benefit by eating the hares.
Commensalism examples are more difficult as it is hard to prove whether the other animal benefits or is negatively impacted.
For example, Remora fish ride other fish and sharks and then eat their leftover food. The sharks and large fish are said not to be affected by the presence of the Remora as they ride them and then eat the leftover food. This interaction would be classed as competitive if Remora fought their hosts for food instead of waiting until they were finished.
Plants with bird or butterfly pollinators are good examples of mutualistic interactions. Plants benefit by having their flowers pollinated so they can reproduce. The butterflies and bird pollinators benefit as they get a delicious nectar meal.

Answer: How does a nation's education system relate to its economic performance? Why do most workers with college degrees earn so much more than those without degrees? Understanding how education and training interact with the economy can help explain why some workers, businesses, and economies flourish, while others falter.
As the labor supply increases, downward pressure is placed on the wage rate. If employers' demand for labor doesn't keep up with the labor supply, wages usually fall. An excess supply of workers is particularly harmful to employees working in industries with low barriers to entry for new employees—that is, those with jobs that don't require a degree or any specialized training.
Conversely, industries with higher education and training requirements tend to pay workers higher wages. The increased pay is due to a smaller labor supply capable of operating in those industries, and the required education and training carries significant costs.
KEY TAKEAWAYS
O The knowledge and skills of workers available in the labor supply is a key determinant for both business and economic growth.
O Industries with higher education and training requirements tend to pay workers higher wages.
O Differences in training levels is a significant factor that separates developed and developing countries.
O An economy's productivity rises as the number of educated workers increases since skilled workers can perform tasks more efficiently.
