The correct answer is - 1,180 km.

North America and Europe move away from one another, though the two plates, the North American and Eurasian are merging together on the other side. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.

To get to the result we only need to multiply the number of years with the annual movement

2 x 200,000 = 400,000

Than divide the result with 100,000, as that is how much cm are in one km

400,000 / 100,000 = 4

And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.

An action potential in one segment of axon causes adjacent sections of axon membrane to reach threshold through what mechanism?
Furkat [3]
<h3>Answer:</h3>

The generation of local currents.

<h3>Explanation:</h3>

An action potential at the axon hillock generates local currents that depolarize nearby sections of axon to threshold. This change in membrane potential causes voltage-gated Na+ channels to open in the adjacent axon segment. This generates/regenerates the action potential in the adjacent segment, causing the action potential to propagate away from the axon hillock.

Answer:

Water is transported from one area to another area that has little water.   Water is collected and salt allowed to settle at the bottom.

Explanation:

Desalination of water is a process of the removal of salts and minerals from the water. This process is used for the production of water suitable for human consumption or irrigation.

Natural desalination occurs trough the hydrologic cycle when seawater evaporates. On the other hand, manipulated desalinization is an energy expensive alternative to natural desalination.

After duplication, at what point does a cell become two cells with identical DNA? starting in prophase end of anaphase end of cy
shepuryov [24]

Answer:

end of cytokinesis

Explanation:

Telophase is the last stage of cell division. It ends with cytokinesis which is the splitting of the mother cells into two daughter cells. The cell pinches in the equator region with the help of a ring of contractile protein filaments. The formed cleavage furrow grows until the two cells pinch off completely.
