1. Critic the following two views from the perspective of today’s sustainability. (50 points)
• Aristotle’s anthropocentric view: "Plants exist to give food to animals, and animals, to give food to men. … Since nature makes nothing purposeless or in vain, all animals must have been made by nature for the sake of man."
• Biocentric outlook by Paul Maylor: It values all living things in Earth’s community, so each organism is "a center of life pursuing its own good in its own way," and all organisms are interconnected.
Answers
Aristotle's anthropocentric view places humans at the center and considers other organisms as means to human ends, whereas the biocentric outlook recognizes the intrinsic value of all living things and emphasizes the interconnectedness and independent pursuit of well-being by each organism.
Aristotle's anthropocentric view, while reflective of the dominant perspective during his time, is heavily criticized from the perspective of today's sustainability. This view places humans at the center and considers the natural world as existing solely for human benefit. It disregards the intrinsic value and interconnectedness of all living organisms and ecosystems. This anthropocentric mindset has led to unsustainable practices, exploitation of natural resources, and the degradation of ecosystems, resulting in environmental crises such as climate change, habitat loss, and species extinction.
On the other hand, Paul Maylor's biocentric outlook aligns more closely with the principles of sustainability. It recognizes the inherent worth and autonomy of all living beings and acknowledges the interdependence of organisms within Earth's community. This perspective emphasizes the need for ecological balance and harmonious coexistence, promoting a more holistic approach to environmental stewardship.
From the standpoint of sustainability, the biocentric outlook offers a more comprehensive and ecologically responsible framework. It encourages a shift away from exploitative practices towards a greater respect for the intrinsic value of nature and the need for conservation and preservation. By recognizing the interconnectedness of all life forms, this perspective promotes sustainable living that supports the well-being of both humans and the natural world.

Answers
Active transport occurs across membranes that c. have a higher concentration of the solute on the outside of the cell.
Active transport is a cellular transport mechanism in which substances like amino acids, glucose and ions are transported across cell membranes to a region were the high concentration of such substances is present .
Active transport is considered as the movement of dissolved molecules into or out of a cell mediated by cell membrane, from a region of lower concentration to a region of higher concentration. These particles then move against the concentration gradient , while using energy released during respiration .

Answers
The bicuspid valve prevents blood flowing back into the option c. left atrium.
The bicuspid valve, also known as the mitral valve, is located between the left atrium and the left ventricle of the heart. Its main function is to ensure that blood flows in one direction, from the left atrium to the left ventricle, and prevents any backflow.
Therefore, the correct option is d. Left ventricle. The bicuspid valve acts as a barrier, closing when the left ventricle contracts, preventing blood from flowing back into the left atrium and ensuring a unidirectional flow of blood throughout the heart

greater prairie chickens once inhabited about every county in wisconsin. by 1930, however, it was estimated that only about 55,000 birds inhabited the state. in 1950, only about 2,500 birds remained in four isolated areas in the center of the state and by 1960 these birds declined in abundance to about half this size (~1,250 birds). since 1960 the number of birds has fluctuated around this level. it is estimated that greater prairie chickens have a generation time of about two years. data were obtained from the mitochondrial dna of historic (1951-1954) and contemporary (1998-2000) samples of birds from wisconsin. the average number of alleles per gene locus were significantly lower in the contemporary samples compared to the historic samples. (hint: having only two alleles per gene is rare in any population). a. using your knowledge of evolution and speciation, what is the most probable explanation for the allele differences observed in the prairie chickens from the 1950's to the 2000's?
Answers
Answer: The most likely explanation for the allele differences observed in Greater Prairie Chickens between the 1950s and 2000s is genetic bottleneck. This occurs when a population experiences a significant reduction in its total size, resulting in a decrease in the amount of genetic diversity within the population. This can lead to a decrease in the number of alleles per gene locus, as individuals may carry the same alleles more frequently due to the reduced gene pool. In the case of Greater Prairie Chickens, it is possible that the population experienced a genetic bottleneck in the late 20th century, resulting in a loss of genetic diversity and a decrease in the number of alleles per gene locus in contemporary samples compared to historic samples.

Answers
Part A: The bull's Darwinian fitness is probably (a.) >1
Part B: The other male seals' Darwinian fitnesses are probably average: (c.) <1
Part C: The average Darwinian fitness of the individuals in the entire population is probably (b.) =1
Part A: Darwinian fitness is defined as the contribution of an individual to the gene pool of the following generation relative to the average for the population, as a result of the selection pressures. An organism with a high fitness level is more likely to survive and reproduce than an organism with a lower fitness level. In the elephant seal population, the sexually dominant bull has the highest Darwinian fitness since it has a greater likelihood of passing on its genes.
Part B: Since other male seals do not get the opportunity to mate, their fitness levels are relatively low, which suggests that their Darwinian fitness level is below average.
Part C: The average Darwinian fitness level of the population is 1 in a stable population that neither grows nor shrinks. This suggests that the rate of the organism's population with a higher fitness level is similar to that of the population with a lower fitness level.

Ecologists use a method of studying a particular population of animal within a community called mark and recapture. A researcher captures, marks, and releases 40 red fox into a large community. He then collects 100 different red fox over the next year. If the recapture rate is 10%, what is a reasonable estimate of the red fox population size?
A) 40.
B) 400.
C) 4000.
Answers
The population size is B) 400. The recapture rate is the number of marked individuals recaptured divided by the total number of individuals captured. In this case, the recapture rate is 10%, so 10% of the population is marked.
The mark and recapture method is a technique used to estimate the size of a population. The method involves capturing a sample of individuals from the population, marking them in some way, and then releasing them back into the population. After a period of time, another sample of individuals is captured and the number of marked individuals in the second sample is counted. The size of the population is then estimated using the following equation:
Population size = (Number of marked individuals in the second sample) / (Recapture rate) * (Total number of individuals captured in the second sample)
In this problem, the researcher captures 40 red fox and marks them. He then captures 100 red fox and finds that 10 of them are marked. The recapture rate is therefore 10 / 100 = 0.1.
The population size is then estimated as follows:
```
Population size = (10) / (0.1) * (100) = 400
```
Therefore, the answer is B.
Here are some of the assumptions of the mark and recapture method:
* The marked individuals are randomly distributed throughout the population.
* The marked individuals do not have a higher or lower chance of being captured than unmarked individuals.
* The population size does not change between the time the first sample is captured and the time the second sample is captured.
The mark and recapture method is a relatively simple and inexpensive method to estimate population size. However, it is important to be aware of the assumptions of the method in order to make accurate estimates.

A species of finch on the mainland has a long, thin beak. It lives in swamps and its main food is insects. A closely related species of finch lives on an island near the mainland. This island has many trees that produce small, hard seeds. What kind of adaptation most likely became common in the island population, in response to its different environment
Answers
The island population of finches most likely developed adaptations such as a larger and stronger beak to efficiently consume the small, hard seeds produced by the trees.
In response to the different environment on the island, the finches likely underwent natural selection favoring traits that allowed them to effectively obtain food from the available resources. With the abundance of small, hard seeds produced by the trees, the finches with larger and stronger beaks would have had an advantage in cracking open and accessing the seeds. Over time, individuals with traits that allowed them to exploit the available food source would have been more successful in survival and reproduction, leading to the increase in the frequency of these adaptive traits within the population.
This process is an example of adaptive radiation, where a population of organisms diversifies and adapts to different ecological niches. In this case, the island population of finches experienced a selective pressure favoring traits that facilitated feeding on the small, hard seeds. Through natural selection, the beak size and strength likely evolved to better suit the new food source, allowing the finches to survive and reproduce more successfully on the island.

Answers
As more and more of the dots move coherently to the left, neurons selective for left movement, large-scale motion stimuli cause the middle temporal visual area's neurons to fire.
The monkey is taught to point its saccadic eyes in the direction of the target to identify the stimulus' movement direction. If a noise-free stimulus is given with all the dots moving in the same direction, the monkey can reliably make the perceptual choice between a dot movement in the cell's preferred direction (P) or the null direction (N) after training. A psychometric function that measures the percentage of saccades to the target P as a function of coherence, where coherence denotes the percentage of coherently moving dots, can be used to evaluate behavioural performance.
