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. Also, India is well know for female infanticide and women are less valued and the fetus is aborted.

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.

Describe how the residents of Belize have adapted to their particular environment.
PolarNik [594]

Belize's population has adapted to use the tropical rainforest and the waters in order to survive in the harsh environment.

Explanation:

Belize is a small country that is cover with dense, tropical rainforest. It comes out on the Caribbean Sea, and it is a country that is abundant with rivers and streams. The tropical rainforest is a very tough place for living, especially if the lifestyle of the population is not of primitive type, so the people are almost exclusively settled along the coastline.

The tropical rainforest is used as a natural, free, high producing garden of fruits, but also lot of plants used for medicine. The people also tend to hunt a lot, as there is an abundance of animals. The primary source of resources though are the rivers and the sea, where the majority of the population is involved in fishing and gathering sea plants.

Significant natural hazards in history in the Pacific Coastal Range:
Maksim231197 [3]

Answer:

Natural processes such as waves, tides, and weather, continually change coastal landscapes. The integrity of coastal homes, businesses, and infrastructure can be threatened by hazards associated with event-driven changes, such as extreme storms and their impacts on beach and dune erosion, or longer-term, cumulative changes associated with coastal and marine processes, such as sea-level rise. Scientists working on Coastal Change Hazards conduct basic and applied research and provide relevant science-based products to assist the Nation with these coastal change hazard challenges. By building a community with a broad range of expertise, CCH facilitates the integration of diverse coastal science and the exchange of new ideas and approaches across the Coastal-Marine Hazards and Resources Program (CMHRP). Innovative collaboration is encouraged in order to identify and address the Nation’s needs and coastal change hazards problems. Through observation and modeling, CCH develops robust and accessible coastal change assessments that help improve the lives, property, and economic prosperity of the Nation’s coastal communities, habitats, and natural resources.

What is geographic variation and how does the term cline relate?
prisoha [69]

Geographic variation was the study or examination that living things which are relatively similar are different because of their habitat and geography was dissimilar. Comparable organisms parted ways by physical features and global positioning.

It depends on the position of the species a cline can happen. This can relate to a specific one of two or more substitute forms of a genetic factor that arise by transformation and are found at the same place on a chromosome which will assist in surviving of a different but reachable geographic location.
