How does the function of the chicken, human, and other vertebrate forelimbs differ?
How might natural selection account for the development of different uses for limbs in different species?
What do these homologous structures tell us about evolution?

Answers

Answer 1

Answer:

The vertebrate forelimb of human, bird, and bat may not appear to have much in common, but a closer examination of the anatomy shows that the same bones were applied to a variety of different jobs in each of these species. Evolution doesn't plan ahead. It can only work with what's available. The color coding shows the way the bony elements were modified in each species. You might think that the two wings would be more similar in design because of the job they do but, in fact, the bird wing and human arm are more similar on the interior. However, the bird "hand" is reduced, whereas the bat and human hand have more in common. See if you can find a similar image of a dolphin or whale flipper for another comparison.

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.

The textual evidence that best supports each of Warren's arguments into the correct box are:

Women are unfairly compensated for their work - Women today still earn only 77 cent for every dollar.

Wage inequality affects a woman's future - Unequal pay makes it harder for them to pay back students loans.

Why does the Supreme Court assert this fact? to highlight the idea that a child’s potential can be measured to illustrate how desegregation will be implemented to highlight the significance of equal access to education to illustrate the importance of high academic standards.

Answers

The court recognizes that people in some localities are being treated unfairly by teachers.

The court recognizes that segregated schools require additional federal funding. The court recognizes that the current delivery of education might compromise citizens' rights.

What is the importance of high academic standards?

Standards ensure better accountability – holding teachers and schools responsible for what goes on in the classrooms.

The practice of aligning learning to standards also helps ensure that a higher level of learning is attained, guides teachers in the process of assessment, and helps keep them on track.

PLEASE HELP ME REVISE MY AXEXES ESSAY !!



The leavers by Lisa Ko is a story about a boy named Deming Guo who assumes his mother abandoned him after a sudden disappearance in his life, later on we come to find out how she was not running away from but was held captive by immigration services for 14 months and later was deported back to China. Deming Guo’s mother was not at fault. Deming changes throughout the book through the relationships he gains after his mother's disappearance. In The Leavers one example would be: “After a few weeks, the wooden floors of the Wilkinsons’ house no longer felt so slippery, and when people said “Daniel” he answered, didn't think they were talking to someone else. No longer did Peter and Kay look as unusual to him, the shade of their skin and the shape of their noses as the low buzz of the empty streets, and he didn't always remember to dial his mother's phone number at night” (Ko 63). From this quote you can conclude the protagonist Deming has gone through many changes in so little time he has accepted himself as who he now is and who the people he is living with are, he is a strong kid. He now has grown to make his own decisions and has grown to be motivated in life and not live under an adult shadow and someone to depend on. In The Leavers another good example would be: '' Maybe he would come back to Fuzhou after New Year's. Either way, it was incredible to decide something. He had never allowed himself to fully trust his choices before” (Ko 331). Also from this quote, you can conclude that Deming Guo has finally grown as a person, and from when he was confused on whether to do music with his friend Roland or listening to Peter and Kay’s Advice on going to college and living the stereotypical successful American life. Lisa Ko did an amazing job at character building throughout the book and how she made Deming go through so much as a child through his adult life. It seemed like he would always have it rough but when he finds himself his life changes for the better instead of having people plan out his life for him. Deming needed to go through that to grow and mature as a person and to be more than a little Asian boy.

The overproduction of goods in the 1920s had a significant impact on the overall economy. During this period, Consumer demand decreased, prices decreased, and the economy slowed. Hence, option C is correct.

The market was overstocked during this time due to industrial growth and technological breakthroughs. Supply exceeded customer demand as a result, which had the following effects:

An essay on Animal Welfare.

Answers

Answer:

Animal welfare is a fairly recent, yet troubling argument in society. This subject is a strong argument on a variety of opinions. Animal welfare has become a major issue and has grown internationally. The human concern and the safety and rights of animals is the meaning of the concept of animal welfare. Through decades of animal welfare, people fight to prevent the action of animal cruelty and bring help towards animal rights.

Towards animal welfare comes the aspect of animal cruelty. Animal cruelty is a fairly recent subject that has affected society. Animal cruelty has now shown comparisons through human abused households. The concern is recent because as society changes humans attitudes change which now affects towards animals. Animal welfare is used to help animal cruelty, because decreasing the violence between animals and humans can help the regulations of animal welfare. Research and testing have become more prominent and a strong concern to the public on the treatment on animals. Many activists today are trying to change the view people see toward the animal they have as a companion. Ethical issues are the many concerns about animals and the question always asked is, "who has the right to control the animal?”

For animal welfare and the causes of animal abuse new research has been created. Since animal abuse is fairly a new subject, new research is constantly brought up. In the Bahamas a study was done in the College of Bahamas, and it states that, “…dogs were equally likely to be considered members of the household in homes without domestic violence,” (Fielding 197). Homes with violence show that humans substitute human victims for animal victims.
