Water is called the "universal solvent" because it is capable of dissolving more substances than any other liquid. This is important to every living thing on earth. It means that wherever water goes, either through the air, the ground, or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Africa and South America are 4,000 km apart. If the plates move away from each other at a rate of 30 km per 1 million years, how
yulyashka [42]

Answer:

The majority of the research shows that the plates move at the average rate of between approximately 0.60 cm/yr to 10 cm/yr. Some sources state that in the North Atlantic, the rate of movement is only about 1 cm (about 0.4 in) per year, while in the Pacific it amounts to more than 4 cm (almost 2 in) annually, while others say that plates, in general, travel from 5 to 10 cm/yr.



The Eurasian Plate is moving away from the North American Plate at a rate the is about 3cm per year. That is about the same rate at which your fingernails will grow.



The distance from New York to London is in 3459 miles (5567 km). What will the distance be in 5 million years?.





The distance from New York to London in 5 million years will be 3552 miles (5717 km). So if today it takes us 7 hours and 30 minutes to fly to London at a speed of 460 miles per hour, in 5 million years at the same rate of speed will take us close to 8 hours.

How can a robin have a ddt concentration of 444 ppm even though the soil contains only 10 ppm of ddt
zaharov [31]

Robin can have a ddt concentration of 444ppm while the ddt concentration of soil is 10 ppm. This happens due to biological magnification.

<u>Explanation:</u>

In biological magnification the concentration of toxic substances at successive trophic levels keeps increasing. Due to biomagnification, what starts out as a small concentration grows  while moving to successive trophic levels. DDT is a pesticide which is used to kill pests that affect crops.

DDT used in farms gets deposited in the soil. From the soil it can reach various trophic levels. At each trophic level its concentration keeps increasing.

Robin is a bird that is a secondary consumer and thus belongs to the higher trophic level. Thus even if the DDT concentration is as low as 10ppm in the soil its concentration will keep increasing and can become a high value like 444ppm.
