The white-tailed ptarmigan lives at high elevations on mountains that receive a lot of snow in the winter. During the summer, the ptarmigans’ feathers are mottled brown. The birds lose the brown feathers and grow a new set of white feathers during the winter. Scientists are concerned that rising global temperatures will affect the white-tailed ptarmigan. If global climate change leads to the elimination of snow in the habitat of white-tailed ptarmigans, which adaptation is most likely to occur over many generations? A.Birds with white feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have brown feathers throughout the year. B.Birds with brown feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have white feathers throughout the year. C.Birds with white feathers will be easier to see on the ground in the summer. Over time this could lead to white-tailed ptarmigans that have white feathers throughout the year. D.Birds with brown feathers will be easier to see on the ground in the winter. Over time this could lead to white-tailed ptarmigans that have brown feathers throughout the year.

Answer:

A. Birds with white feathers in areas without winter snow will be easier for predators to find. Over time this could lead to white-tailed ptarmigans that have brown feathers throughout the year.

Explanation:

As stated explicitly in the passage, the white snow allows for easier survival of the ptarmigans who have white feathers covering their whole body. Despite their feathers becoming mottled brown in summers, they shed those brown feathers and grew white feathers in the winters.

This regrowth of white feathers is to offer them better 'concealment' from predators, for their feathers will be the same as those white snows and thus, making it difficult for any predators to locate them quickly. But if the global temperature continues rising rapidly, then the snows will melt and leave the birds vulnerable, with no chance of survival. The elimination of the snow in their habitat will make them easy targets, with their white feathers easily visible amidst the brown mountains instead of the white snow-covered mountains.

Thus, the correct answer is that birds with white feathers will be easier for predators to find in areas where there is no winter snow. This could then lead to white-tailed ptarmigans with brown feathers throughout the year.

Seniors at a public high school can pay for a block on a wall to paint as they please to leave their mark. Some students choose to include Bible verses on their blocks. A group of parents lodge a complaint with the school board, saying that their children have to walk by the wall and should not have religious speech forced on them. The parents say that since it is a public school, the practice violates the establishment clause. The school board orders the existing verses to be painted over and bans the use of religious speech on the blocks. A group of students challenge the ban, claiming that it violates their right to free expression and free exercise of religion. Prepare an essay in the form of an argument on whether or not the local school board has violated the students' rights under the Constitution. In your essay, you must: Articulate a defensible claim or thesis that responds to the prompt and establishes a line of reasoning Support your claim or thesis with at least TWO pieces of accurate and relevant information: At least ONE piece of evidence must be from the U.S. Constitution (including amendments) At least ONE piece of evidence must be from Wisconsin v. Yoder (1972) or Engel v. Vitale (1962) Use reasoning to explain why your evidence supports your claim/thesis Respond to an opposing or alternative perspective using refutation, concession, or rebuttal

On November 29, 1937, several individuals gathered at the headquarters of the Committee for Industrial Organization (CIO) in Jersey City, New Jersey to initiate a recruitment drive and discuss the National Labor Relations Act. Acting on the orders of Mayor Frank Hague, police seized the group's recruitment materials and refused to allow the meeting to take place. Hague argued that he was enforcing a 1930 city ordinance that forbade gatherings of groups that advocated obstruction of the government by unlawful means. Hague referred to CIO members as "communists." Arguing that the ordinance violated the First Amendment protection of freedom of assembly, the group filed suit against several city officials, including Hague. A district court and the United States Court of Appeals for the Third Circuit agreed and invalidated the ordinance. In Hague v. Committee for Industrial Organization (1939), the Supreme Court concluded that the actions taken by police clearly violated the First Amendment as it applied to the states. "Citizenship of the United States would be little better than a name if it did not carry with it the right to discuss national legislation and the benefits, advantages, and opportunities to accrue to citizens therefrom." Relying on the Court's previous ruling in the Slaughter House Cases, Justice Roberts wrote that freedom of assembly is "a privilege inherent in citizenship of the United States" and that no "contrary view has ever been voiced" by the Court.
