Answer:
Darwin's observations led him to wonder: How do species originate?
Explanation:
Darwin observed morphological traits and geographic distribution of many species as well as many fossils. From these observations the question: How do species originate?, arose. Darwin concludes that similar species must originate from a recent common ancestor with similar traits to all their descendants. This is the basis of the theory of evolution.
Answer:
The correct answers are "A magnetic field is the area around a magnet where a force is exerted on certain objects", "Magnetic field lines spread out of the north end of the magnet" and "Magnetic fields are three-dimensional and resemble a bubble".
Explanation:
Three statements that define a magnetic field are:
1. "A magnetic field is the area around a magnet where a force is exerted on certain objects". Magnetic field force is driven by moving electric charges and the objects that are susceptible to the forces are known as electromagnetic objects.
2."Magnetic field lines spread out of the north end of the magnet". Magnetic fields are taken to be outward from the North pole to the South Pole. This direction takes place on Earth as well, because Earth function as a giant magnet.
3. "Magnetic fields are three-dimensional and resemble a bubble". Magnetic field forces are driven following a bubble like configuration and affects the objects upon this configuration.

Answer: True
Ocean water is saline. The salt in the ocean comes from rocks on land. The rain falls on the rocks erodes the rocks . The rain being acidic in nature due to the presence of carbonic acid creates ions, or electronically charged atomic particles. These ions are carried away by the streams of rivers and ultimately to oceans. The two of the most abundant ions produced by this process are sodium and chloride. These make up 90% of dissolved ions in the ocean. The concentration of the salt in seawater is about 35 parts per thousand. In other words about 3.5 percent of the weight of seawater comes from the dissolved salts.
