The picture below shows one cell dividing into two cells. Which of the following statements is best supported by the picture shown above
Apologies for the confusion. Since the picture is not available, I cannot provide a specific statement that is best supported by the picture. However, in general, if the picture depicts one cell dividing into two cells, it would support the statement that the process shown is cell division or mitosis, which is a fundamental process in the growth and reproduction of cells.
Thousands of golden toads, shown below, used to occupy the tropical forests of Costa Rica. In the late 1980s, however, unusually warm weather caused many of the pools that the toads used as breeding areas to dry up. By 2004, the golden toad was listed as extinct. This example demonstrates how:
This example demonstrates how climate change and habitat loss can lead to the extinction of a species. The unusually warm weather caused the drying up of the pools, which were crucial breeding areas for the golden toads. With their breeding habitat gone, the toads were unable to reproduce and sustain their population. Over time, the lack of suitable conditions led to their extinction.

The Earth has spheres that are constantly interacting. Which of the following is the best example of the geosphere interacting with the biosphere?
The best example of the geosphere interacting with the biosphere is when volcanic eruptions occur. During a volcanic eruption, molten rock from the geosphere, known as lava, is released onto the Earth's surface. This lava can create new landforms and alter the topography of the geosphere. However, it also provides new opportunities for the biosphere to interact. Over time, plants and organisms can colonize the newly formed volcanic land, leading to the establishment of new ecosystems. The nutrients released from volcanic eruptions can enrich the soil, allowing for the growth of vegetation and eventually supporting diverse animal life. This interaction between the geosphere and biosphere is an essential part of the Earth's natural processes and the interconnectedness of its various spheres.

The following image is a prediction of how an earthquake would spread from the epicenter (marked by a star). Red indicates the worst areas, and green indicates the places where there is the least shaking. Water is colored blue. Consider a seismic wave—an earthquake—that starts in the middle of the red area and travels outward along the surface of the earth. Point A is the same distance from the epicenter as point B. Using what you know about the movement of waves, how would you expect the seismic waves to be different at point A and point B?(1 point)
