Answer: D) a hollow soccer ball
Explanation:
Carbon is capable of forming many structurally different forms of the same element due to its valency. These forms are called allotropes. One of these is the buckminsterfullerene. It has a cage-like fused-ring structure made of twenty hexagons and twelve pentagons. If you look at this structure, it resembles a soccer ball.

Answer:
The mouse and shrew bones were common to all three owls so they were not useful in identifying environments. The gopher bones were unique to the great grey owl of Alaska. Gophers are rodents that are successful in areas with soft soil and lots of grass, so the gopher and this owl would be found in the meadows and evergreen forests of Alaska. The bat was unique to the barking owl of Australia. The bat would be found in woodland habitats where there are many trees the bat can hang from. The gull bones were unique to the short-eared owl of Cuba. Gulls are wetland birds, so the gull and this owl would be found in marshes and coastal areas.
Answer:
Use the rule that 10% of the energy is transferred between layers.
Explanation:
Energy is transferred between layers of a food pyramid. That means that the producers at the bottom of the pyramid (e.g. green plants) provide energy to the primary consumers (e.g. rabbits), which are eaten by and provide energy to the secondary consumers (e.g. foxes).
However, very little of the energy is actually transferred to the next layer, roughly 10%. So an easy way to calculate the energy available at each level is to calculate 10% of what was available from the previous level. So if there is 600 kJ available from the primary consumers, then 60 kJ are transferred to the secondary consumers
