Answer:
-3
Explanation:
it is in the form y = mx + b
m is the slope and b is the y intercept. And so it is -3.
When scientists plotted the points of normal and reversed polarity on a seafloor map the type of pattern that did they discover in the magnetic polarity is option A: stripes of normal and reversed polarity.
<h3>
What do you mean by Reversed Polarity?</h3>
The presence of reverse magnetic polarity found in the opposite sides that is south and northern parts of the ridges is due to the magnetic properties of the magma which get aligned to the earth's magnetic fields.
Magnetism on the seafloor leads to ridges having reversed and normal polarity. These ridges often alternate. The reverse polarities and old and new sea floors are found in association to the spreading of magma in the opposite direction of the ridges.
The first ridge to the right will have a normal polarity. The next ridge will be reversed and this trend will then repeat till the end.
Therefore, correct option is A.

Answer:
Life began on Earth at least 3.5 to 4 billion years ago, and it has been evolving ever since. At first, all living things on Earth were simple, single-celled organisms. Much later, the first multicellular organisms evolved, and after that, Earth's biodiversity greatly increased.
Explanation:
State Route 88 (SR 88), also known as the Carson Pass Highway, is a California State Highway that travels in an east–west direction, from Stockton, crossing the Sierra Nevada at Carson Pass, and ending at the border with Nevada, whereupon it becomes Nevada State Route 88, eventually terminating at U.S. Route 395.
The answer is B) 50. It's actually about 55 miles, but 50 is the closest answer. <span>Russia and Alaska are divided by the Bering Strait, which is about 55 miles at its narrowest point.
