Answer:
4) The rate of species extinction is lower on the small island than on the large island.
Explanation:
The theory of island biogeography suggested that because of the size and links to the mainland. Fewer species that are not from the island will invade because the distance from the mainland is greater. The threat of extinction due to this is low. The small island also has a lower capacity for different species due to limited resources. This would mean that there are simply fewer species to go extinct.
Answer:
The practice of female infanticide.
Explanation:
Some countries, especially China, India, have practiced female infanticide due to the fact that they regard males as superior. As for China an addition factor might have been the one child rule applied for a long time although this law has been relaxed in the last few years and you can now have 2 children.

India has cause to fret. According to two demographers, John Bongaarts and Christophe Guilmoto, a staggering 45m girls and women are missing from the country. Some were never born, having been detected by ultrasound scans and aborted. Others died young as a result of being neglected more than boys. Some villages in the north have an alarming surplus of boys and young men. Yet attitudes and behaviour are changing. In India, and in the world as a whole, the war on baby girls seems to be winding down.
Answer:
A mid-ocean ridge
Explanation:
A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.
