In many parts of the United States, homeowners use a significant portion of their energy budget to heat their home in the winter. It has been determined that lowering a thermostat by 3 degrees F in the winter can reduce the energy costs by about 10 percent in many homes. An individual homeowner lowers their thermostat by 3 degrees exactly halfway through the billing period. For the month that the thermostat was lowered, the heating bill was $95. How much money did the family save in the month in which they lowered the thermostat setting halfway through the billing period?
A. $2.85
B. $5
C. $9.50
D. $10
Answer:
B. $5
Explanation:
$95/10 percent = 9.5
9.5/2 (because it is halfway through the billing period) = 4.75
4.75 rounded up to the nearest tenths place is 5.

6.B:Compare processes by which state power shifted in various parts of the world from 1750 to 1900.
Answer:
Hope this helps
Explanation:
The United States gained both political and economic power in the global stage between 1750 to 1900, as many European nations gain new territories to add to their empire. Many nations that Europeans colonized became weakened and poor during this time period.
Imperialism is the process by which one country extends its power and influence over another country, mainly through colonization and military conquests.
The periods between 1750 and 190 was the period which was known as the Age of Imperialism where European superpowers claimed lands belonging to weaker nations and colonising them.
During this period, we can see that there wa the Scramble for Africa after the Berlin conference with Otto Von Bismarck and other Europeans as they came to Africa to colonise and it did not stop there, as they also went to Asia.

A. I, II, and III
B. II and III only
C. III only
D. I and III only
Answer: B. II and III only
Explanation: I took the test
Requirements to receive USDA certification for organic agriculture include only diseased animals are allowed antibiotics and no animals can be exposed to artificial hormones or pesticides. Thus, option D is correct.
What is USDA serving standards?The USDA serving standards are the reference amounts of food and drink that are used to provide information about the nutritional content of foods. These standards are based on the amounts of food and drink that people are physically able to consume in one sitting and are intended to be used as a reference for planning and documenting the nutritional intake of individuals and groups.
The USDA serving standards are established by the United States Department of Agriculture (USDA) and are used in the nutrition labeling of foods. They are intended to help people make informed choices about the foods they eat and to encourage the consumption of a healthy and balanced diet.
Thus, option D is correct.

Potatoes were originally domesticated in the Andean Highlands and are now grown commercially in many parts of the world.
A) Describe TWO differences between the methods of potato production shown in image 1 and image 2
B) Explain the process by which the potato diffused from its hearth of domestication to other continents
C) Explain how the agricultural practice shown in image 2 may affect local environmental sustainability
D) Explain the degree to which the practice of monocropping may lead to local food insecurity
E) Explain how potato farming may help small family farms in developing countries transition out of subsistence farming
A)
Image 1 shows traditional farming methods for potatoes, likely in the Andean Highlands. The plot is small and the potatoes are grown in individual holes or furrows. The soil appears to be dug by hand or with simple tools. In contrast, image 2 shows modern commercial potato farming methods, likely in a developed country. The plot is large and the potatoes are grown in neat rows using machinery. The soil is likely prepared with industrial equipment.
B)
The potato was first domesticated in the Andean Highlands of South America over 7,000 years ago. From there, it diffused to other parts of the Americas and eventually to Europe after Spanish explorers brought it back with them in the 16th century. It then spread to other continents through trade, colonialism, and immigration. The potato's ability to thrive in diverse climates and soils made it an important crop in many regions, and its high yields and nutritional value helped to sustain growing populations.
C)
The agricultural practice shown in image 2, monocropping, may negatively affect local environmental sustainability. Monocropping involves planting a single crop in a large area, which can deplete the soil of nutrients and increase the risk of pests and diseases. This can lead to the use of pesticides and fertilizers, which can have negative environmental impacts. Additionally, monocropping can reduce biodiversity and harm ecosystems by replacing natural habitats with monoculture fields.
D)
The practice of monocropping can lead to local food insecurity if the crop fails or is affected by pests or diseases. Since monocropping involves planting a single crop in a large area, a pest or disease outbreak can quickly spread and destroy the entire crop. This can lead to food shortages and price spikes, making it difficult for people in the area to access enough food. Additionally, monocropping can lead to a loss of traditional crops and farming practices, which can further reduce food security by limiting the diversity of available crops.
E)
Potato farming may help small family farms in developing countries transition out of subsistence farming by providing a reliable source of income and food. Since potatoes are a high-yield crop that can thrive in diverse climates and soils, they can be a valuable cash crop for farmers. By selling their potatoes, farmers can earn income that they can use to invest in their farms, purchase equipment or other supplies, or pay for education or healthcare. Additionally, potatoes are a nutritious food that can help to improve the health and well-being of farming families and their communities.
