House sparrows in the northern part of North America are larger than those found in the southern regions. The possible mechanism of microevolution is more likely to be responsible for this is natural selection. The answer would be letter B.
Answer:
This means that the means height (which is all the sum of the height of all the students divided by their number ) is 205 cm. Standard deviation means how the height of the students deviates from this mean since students do vary in height and are not all the same height of 205 cm. Therefore, in this case, the amount of standard dispersion of the students' height is by 17 cm on either lower or higher side of the mean.
Answer:
The continental plate is the location where volcanoes form when the convection in the asthenosphere creates a column of material that rises until it reaches the crust.
Explanation:
Volcanoes form at the edges of Earth’s tectonic plates. When the continental plate moves over the oceanic plate, it causes the oceanic plate to descend into the mantle where some of it melts, and the molten material moves into the mantle above the plate and causes the mantle to melt.
This liquid rock, called magma, rises to the surface because it is less dense then the surrounding rock, a volcano forms when the magma reaches the surface of the Earth at the continental plate.
