When a mass of hydrogen has enough density, it begins to fuse the hydrogen atoms together. This fusion process creates large amounts of heat and light.
When a mass of hydrogen begins the fusion process, it is classified as a —
Star

A particular type of bird carries the genes for its offspring to either have a short, strong beak or a long beak. The strong beak is great for crushing nuts, while the longer beak is used to get to water in little spaces. Normally, 75% of the bird population have short, strong beaks while only 25% have long beaks.
If the area in which the birds live experiences a 50-year drought, what change in beak type could be expected in the population?
More birds would have a long beak.

How does urbanization increase surface runoff?
A. Man-made structures such as roads and parking lots do not allow water to percolate through the soil to the aquifer.
B. Farming techniques channel water to the end of crop rows and then immediately into drainage ditches.
C. Lumber industries leave fallen tree branches and forest debris when it falls and this causes water to stagnate.
D. Drilling for oil and natural gas causes huge cracks to form on the surface and water from rain rushes to the ground below.

Students use a topographic map to study the effects of erosion. The topographic map is shown.
What statement correctly explains where more eroded soil will collect?
More soil collects at area Z because that area is a depression.

Most of the space in the universe is empty. Part of the reason for the emptiness of space is that the matter in the universe is gravitationally attracted to other pieces of matter. Most matter in the universe gets pulled into one of the many massive systems held together by the gravitational pull of black holes. These massive systems can be millions of light years wide and contain millions of stars and planets.
What do scientists call these massive systems?
Galaxies

All of the organisms in this desert biome compete for the same limited resources. The red harvester ants in the food web above were killed when a landowner used fertilizer to try and grow a new crop. Which consumer in the food web would immediately be affected by the lack of red harvester ants?
Mantid
