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: This seems to make the most sense. The birds with the Brown feathers are more likely to survive and reproduce so they will pass the trait of retaining Brown feathers year round to their offspring. This is likely to continue as long as there is no snow in the winter environment.

The correct response is - 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.

In a biological relationship known as predation, one organism—the predator—kills and consumes another—its prey. This type of feeding behavior belongs to a group that also includes parasitism, micropredation, and parasitoids.

Predators have a significant impact on the environment. They affect the structure of ecosystems by dispersing seeds and nutrients from foraging. Additionally, they influence lower species in the food chain by regulating the location, quantity, and variety of their prey, a phenomenon known as trophic cascades.

The four stages of predation are search, recognition, trap, and handling. At each of these stages, the prospect of co-evolution between predator and prey exists. Predators scour their surroundings for suitable prey.

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. Source: Oyez, Hague v. Committee for Industrial Organization (1939) Identify a constitutional provision that is common to both Hague v. Committee for Industrial Organization (1939) and Schenck v. United States (1919). Based on the constitutional clause identified in part A, explain why the facts of Hague v. Committee for Industrial Organization led to a different holding than the holding in Schenck v. United States. Explain how an interest group could use the holding in Hague v. Committee for Industrial Organization to further its agenda.

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.
