A scientist was studying the effects of oil contamination on ocean seaweed. He believed that oil runoff from storm drains would

keep seaweed from growing normally. He had two large aquarium tanks of equal size. He kept the amount of dissolved oxygen and the water temperature the same in each tank. He added some motor oil to one tank but not to the other. He then measured the growth of seaweed plants in each tank. In the tank with no oil, the average growth was 2.57cm/day. The average growth of the seaweed in the tank with oil was 2.37cm/day. Based on this experiment, answer the following questions:
What was the question that the scientist started with?
What was his hypothesis?
Identify the independent variable.
Identify the dependent variable.
Identify the control(s).

What adaptations of the wild yak enable it to survive in the alpine biome?
elixir [45]

The alpine biome is one of the coldest biomes on the planet, it is generally because of the high altitudes. The summer temperature varies in between -12 to 10 degree Celsius, and the average precipitation in the biome is about 30 cm in a year.  

The animals living in the region, adapt to the cold by migrating to warmer regions, hibernating, or insulating their bodies with the help of fat and fur layers. Their bodies seem to possess shorter tails, legs, and ears, in order to minimize the loss of heat.  

One of the animals living in the alpine biome is the wild yak, the animal has adapted to the biome with the help of dense and wooly coats, specially amended feet, horns to dig for food, and if necessary does the migration in winter times to the warmer regions.

2. How well do you think scientists can predict where a volcano will erupt?
masya89 [10]
Volcanologists can predict eruptions—if they have a thorough understanding of a volcano's eruptive history, if they can install the proper instrumentation on a volcano well in advance of an eruption, and if they can continuously monitor and adequately interpret data coming from that equipment.
