The correct answer is dynamo theory. The theory that explains the source of Earth's magnetic field is the dynamo theory. This theory proposes the mechanism of a celestial body such as Earth to generate magnetic field.
Answer:
The right answer is D. The benthic zone
Explanation:
The limnetic and the littoral zone all get a lot of sunlight so there are a lot of plant life. The pelagic zone hosts a variety of plant species so this cannot be the correct answer. That leaves us with the benthic zone.
Benthic meaning inhabiting bottom areas or substrates. Plant life at the bottom is very scarce but there are a lot of insect species.
Answer:
A. 50, 88, 145, 227
Explanation:
The correct option would be option A.
<u>When something grows exponentially, it means the growth increased at a high rate. More specifically, each rate of increase results in more or less doubling of the preceding rate. For example, if the current value of growth rate is 2 for a substance that is growing exponentially, the next growth rates will be 4, 8, 16, etc.</u>
<em>In this particular illustration, the only option that best fit into an exponential system is option A in which the growth rate more or less doubles each time from 50 to 88, from 88 to 145, and then from 145 to 227.</em>
