The first primates known for their extensive use of tools were
A. Homo habilis.
B. Homo erectus.
C. Homo afarensis.
D. Homo sapiens.

Answers

Answer 1

The first primates known for their extensive use of tools were Homo habilis. The correct option is A.

These early hominids, also known as "handy man," lived approximately 2.1 to 1.5 million years ago. Homo habilis is believed to have used tools primarily for food processing, such as cutting meat and cracking open bones for marrow. This development of tool use marked a significant milestone in human evolution, as it allowed these early humans to access resources that were previously inaccessible.

Other hominids such as Homo erectus, Homo afarensis, and Homo sapiens also utilized tools, but Homo habilis is credited with the first extensive use of tools in the hominid lineage. The ability to create and use tools played a crucial role in the survival and adaptation of these early human ancestors, enabling them to expand their diet, improve hunting techniques, and better defend themselves from predators.

This early innovation in tool use eventually paved the way for more advanced technologies and the development of human civilization as we know it today. The correct option is A.

In what ways did the different forms of protest work together to bring about change?

Answers

The different forms of protest, such as peaceful demonstrations, boycotts, strikes, and civil disobedience, worked together in various ways to bring about change.

These forms of protest complemented each other by creating a collective impact that forced authorities to take notice and respond to the demands of the protestors.

Peaceful demonstrations allowed large numbers of people to gather and voice their concerns, attracting attention from the media and the public. This raised awareness and put pressure on those in power to address the issues at hand.

Boycotts, on the other hand, economically hit the target by depriving them of financial support. This made the protest movement more difficult to ignore, as it affected the profit margins and reputation of the targeted institutions or industries.

Strikes, particularly in the workplace, disrupted business operations and demonstrated the power of workers to withhold their labor until their demands were met. This forced employers to negotiate and make concessions to avoid further disruption.

Civil disobedience involved intentionally breaking unjust laws, leading to arrests and legal battles. These acts of defiance highlighted the injustice and hypocrisy of existing laws and galvanized public support for change.

Overall, the combination of these different forms of protest, with each playing a specific role, helped to create a unified and effective movement that successfully brought about change.

Answers

If we wanted to look at the proximate causes of "why do we laugh" from an ontogeny perspective, the question to be asked is A.) How does laughter change across development?

From an ontogeny perspective, focusing on the proximate causes of "why do we laugh" means examining how laughter changes and develops throughout an individual's lifespan. This question delves into the developmental aspects of laughter, such as how laughter evolves from infancy to adulthood and whether there are any specific triggers or changes in the expression of laughter across different stages of development.

By asking about the changes in laughter over time, we can gain insights into the physiological, cognitive, and social factors that contribute to the development of laughter in individuals. Therefore, the question of how laughter changes across development aligns with the ontogeny perspective.

how does government budget deficit affect interest rates investment and economic growth

Answers

Government budget deficits can lead to increased interest rates, reduced investment, and slower economic growth.

Government budget deficits occur when the government spends more money than it receives in revenue. This creates a shortfall that must be financed through borrowing. When the government borrows money, it competes with other borrowers in the financial market, increasing the demand for loanable funds. This increased demand for funds puts upward pressure on interest rates.

Higher interest rates discourage private investment because borrowing becomes more expensive for businesses and individuals. When investment declines, it can lead to reduced economic growth. Investments in capital goods, research and development, and infrastructure are essential drivers of productivity and economic expansion. When businesses curtail their investment plans due to higher interest rates, it can result in slower growth and potentially a contraction in economic activity.

Moreover, persistent budget deficits can lead to concerns about the government's ability to repay its debts. This can erode investor confidence and increase the perceived risk associated with lending to the government. As a result, lenders may demand higher interest rates to compensate for the increased risk, further pushing up borrowing costs.

To manage earnings more efficiently, Michelle changes bed debt estimation to the balance sheet method at 4%. How much is the difference in net income between the income statement and balance sheet methods

Answers

The difference in net income between the income statement method and the balance sheet method is $3,100.

To calculate the difference in net income between the income statement method and the balance sheet method for bad debt estimation, we need to compare the bad debt expense recorded under each method.

Under the income statement method, the bad debt expense is recognized as a percentage of credit sales. In this case, it is 4% of $345,000, which equals $13,800.

Under the balance sheet method, the bad debt expense is calculated as a percentage of accounts receivable. The accounts receivable at the end of 2019 is $267,500, and 4% of this amount is $10,700.

To find the difference in net income, we need to subtract the bad debt expense calculated under the balance sheet method from the bad debt expense calculated under the income statement method:

Difference in Net Income = Bad Debt Expense (Income Statement Method) - Bad Debt Expense (Balance Sheet Method)

= $13,800 - $10,700

= $3,100

Therefore, the difference in net income between the income statement method and the balance sheet method is $3,100.
