Above is the deer population of Routt County National Forest between 1905 and 2005. The First White-tail deer were introduced to the forest for hunting in 1905. They are not native to the area, though they thrived in the environment.

White tailed deer eat the seeds of coniferous trees, berries, and an assortment of other plants. They tend to roam in small family herds and stick to areas where water is abundant and is unlikely to freeze completely in the winter.

In 1995, an environmental scientist watched a small herd of deer for ten days, recording their movements and taking note of herd size and stopping place. Below is a chart of his results.

Aproximately how many deer per year were added to the population between 1905 and 1920, assuming 1905 marks the 'zero hour' when the deer were first introduced?

Researchers are curious about the effects of large amounts of steam released by a power plant. They hypothesize that the large amounts of moisture might affect precipitation in the area. They record yearly rainfall at multiple locations at various distances from the power plant and find the results below:

At what tested distance from the power plant is rainfall the highest?

Explorers have discovered a new planet, Planet K. It is known that Planet K has magnetic poles to similar to those of Earth, so the explorers decide that using a compass to navigate is possible. When navigating Planet K's surface, it is discovered that the compass points north for a distance then flips so that it points north in the opposite direction for a distance, before returning to pointing north in the original direction. It is known that the magnetic poles of the planet flip every 100 years. Weather is recorded on the planet for 250 years. 

How does the flipping of the magnetic poles affect the weather on Planet K? 

Scientists have long debated the origin of organic molecules on Earth. Organic molecules are those based on the atom carbon, which can form four distinct bonds in contrast to the fewer number allowed in most other non-metals. As a result of this property, carbon can give rise to the enormously complex molecular shapes necessary for life to arise.

Some scientists argue that organic matter was dissolved in water ice on comets, and brought to Earth early in its history. These comets crashed into the early Earth, and deposited carbon-based molecules in copious quantities to the Earth’s surface as their water melted.

In 2014, the first space probe landed on the comet 67P/Churyumov-Gerasimenko. Suppose that scientists find the following information from 5 distinct samples after landing on the comet. Each sample was taken at a single geographical location, but 5 meters deeper than the last. Sample 1 was taken at a depth of 1 meter below the surface.

These samples were compared to 5 similar samples from the surface of Mars. Scientists posited that this comparison would be meaningful because we know that life does not exist on Mars the same way that it does on Earth. Thus, they are comparing a known non-biological celestial body, Mars, with another celestial body, the comet, which may be seeding life on suitable plants.

On the comet, the best description of the relationship between depth of sampling and the concentration of organics is:
