The graph below shows the decline in the catch of groundfish (such as cod, haddock and flounder) from Georges Bank between 1965-1995. This decline in the fish harvest resulted in the closure of large portions of the fishery. Based on this data, what is the rate of decline in the fish harvest, in metric tons per year, from 1965-1995?
Answers
Answer:
Approximately 22,000 metric tonnes of fish per year
Explanation:
From the graph,
Rate of decline :
(metric tonnes of fish in 1965 - metric tonnes of fish in 1995) / range of years
(700,000 - 40,000)metric tonnes ÷ (1995 - 1965)
660,000 metric tonnes ÷ 30 years
660,000 / 30
= 22,000 metric tonnes per year
Approximately 22,000 metric tonnes of fish per year

1. What distinctions does Plato make between the public and the private? Would you make the same distinctions (see paragraphs 53-55)?
2. In paragraph 49, Plato states that the virtue of wisdom “contains a divine element.” What is “a divine element”? What does this statement seem to mean? Do you agree with Plato?
100 POINTSSSSSSSSSSSSSSSSS
Answers
Plato distinguishes the public from the private and its importance for the development of the State. On the other hand, the virtue of wisdom contains a divine element that is justice.
Plato (427ac -347ac) is one of the Greek philosophers best known for his contributions to philosophy, politics, and religion. One of the highlights of Plato is that he was a follower of Socrates and a teacher of Aristotle.
His most outstanding work is the writing of The Republic where he groups all his philosophical ideas. One of the topics he deals with in this book is that of private property.
Plato defended state-controlled private property for the benefit of the lower classes. On the other hand, he rejected the right to private property for the ruling class because he considered that it avoided corruption, personal enrichment, and the use of public power for self-interest. Therefore, the ruling classes had to live communally, sharing all their possessions.
On the other hand, for Plato the divine element of wisdom was justice, that is, the ability to reason inscribed in its essence can be deployed in the political form of the city-state, which allows the community to establish a just order and the individual to live in such a way as to achieve legitimate satisfaction, under the rule of law.

Firstly, the physical transformation of urban areas can be used as a symbol of progress and modernization, allowing the new leader to showcase their ability to bring about positive change. This can create a sense of optimism and confidence among the population, strengthening their support for the leader and their policies.
Secondly, the new urban structure can be strategically designed to promote specific cultural or political narratives. For example, the construction of iconic buildings or landmarks that reflect the leader's ideology or promote a particular cultural identity can help solidify their power and influence. These structures become symbols that people can associate with the leader, further enhancing their cultural or political significance.
Lastly, the change in urban structure can also lead to social and economic development, improving the overall quality of life for residents. This can generate a sense of gratitude and loyalty towards the leader, as they are perceived as responsible for the positive changes. In turn, this strengthens their political power and support base.
Overall, the change in urban structure provides an opportunity for a new leader to shape the physical environment in a way that reinforces their cultural or political power, influences public perception, and garners support from the population.

Alex is in a serious car accident where he was not wearing his seatbelt. He suffered brain damage. Describe specifically how his behaviors/actions could be impacted if the following areas of the brain suffered damage: (a) medulla (b) cerebellum (c) reticular formation (d) pons. After two months, he miraculously improves. The doctors order a series of tests to determine what exactly the cause of his improvement is. What were they planning to see by ordering the following tests? (a) EEG (b) fMRI (c) PET
answer in a few paragraphs and number each answer
Answers
1. If the medulla suffered damage, Alex's behaviors/actions could be impacted in several ways. The medulla is responsible for vital functions such as heart rate, blood pressure, and breathing. Damage to the medulla could lead to irregularities in these functions, potentially causing changes in Alex's heart rate, blood pressure regulation, and breathing patterns. He may experience difficulties in maintaining a stable heart rate and blood pressure, leading to symptoms like dizziness, lightheadedness, or shortness of breath. In severe cases, it could even result in life-threatening complications.
2. Damage to the cerebellum could affect Alex's coordination and balance. The cerebellum plays a crucial role in motor control and coordination. If injured, Alex may experience difficulties with fine motor skills, muscle coordination, and balance. He may have trouble with precise movements, such as reaching for objects or walking steadily. Additionally, damage to the cerebellum can lead to problems with posture, muscle tone, and overall motor control.
3. The reticular formation is responsible for regulating arousal, attention, and sleep-wake cycles. Damage to this area could result in changes in Alex's level of consciousness and overall arousal. He may experience difficulties in maintaining attention and focus, leading to reduced alertness and increased drowsiness. It could also impact his sleep patterns, causing disruptions in the sleep-wake cycle and potentially leading to excessive sleepiness or insomnia.
4. The pons plays a critical role in relaying information between different regions of the brain and coordinating motor movements. Damage to the pons could affect Alex's ability to control voluntary movements and could lead to muscle weakness or paralysis in certain areas of the body. It may also impact his ability to communicate effectively, as the pons is involved in speech production.
After two months, the doctors ordered a series of tests to determine the cause of Alex's improvement:
(a) EEG (electroencephalogram): The doctors likely ordered an EEG to assess the electrical activity in Alex's brain. It can help identify any abnormal brain wave patterns or signs of seizure activity. By comparing the EEG results to previous recordings, they can determine if there are any changes in brain activity that may explain Alex's improvement.
(b) fMRI (functional magnetic resonance imaging): An fMRI provides detailed images of brain activity by measuring changes in blood flow. The doctors may have ordered an fMRI to identify any specific brain regions that show increased activity, suggesting neural recovery or compensation. It can help identify if certain areas of the brain are functioning better than before and provide insights into the neurological basis of Alex's improvement.
(c) PET (positron emission tomography): PET scans involve injecting a radioactive tracer into the body to measure metabolic activity in different organs, including the brain. By ordering a PET scan, the doctors can assess the overall metabolic activity and blood flow in Alex's brain. It can help determine if there are any areas of increased or improved brain activity that may be contributing to his recovery.
These tests allow the doctors to gather objective data and assess the physiological changes in Alex's brain, helping them better understand the underlying mechanisms behind his improvement.

A car of mass 1500 kg collides with a wall during a crash test. all of the energy transferred during the collision is absorbed by the crumble zone. if the energy absorbed by the crumble zone is 4.3 x 10 to the power of 5 j, show that the speed of the car before the collision is 24 m/s.
Answers
To solve this problem, we need to use the principle of conservation of energy. The energy before the collision (kinetic energy) is equal to the energy absorbed by the crumble zone after the collision. The formula for kinetic energy is:
KE = 1/2mv^2
where KE is the kinetic energy, m is the mass of the car, and v is its velocity (speed).
The energy absorbed by the crumble zone is given as 4.3 x 10^5 J.
So, we can write:
KE = 4.3 x 10^5 J
1/2mv^2 = 4.3 x 10^5 J
We know the mass of the car is 1500 kg. So, we can plug in the values:
1/2 x 1500 x v^2 = 4.3 x 10^5
Simplifying this equation, we get:
v^2 = (4.3 x 10^5 x 2) / 1500
v^2 = 573.33
v = sqrt(573.33)
v = 23.95 m/s
Therefore, the speed of the car before the collision is approximately 24 m/s.
