Answer:
It may be that synthesis in population dynamics has been slow to emerge because population change is more complicated than it first appears. After all, population change is determined ultimately by only four factors: birth, death, immigration, and emigration.
Explanation:
Research has shown that population size and growth are important factors in the emission of greenhouse gases. ... While population-driven emissions from developed nations are estimated to contribute 42 percent of CO2 emissions between 1985 and 2020, they are expected to contribute only 3 percent between 2025 and 2100.
If sewage is only partially treated before it is disposed of, it can contaminate water and harm huge amounts of wildlife. Alternatively, leaking or flooding can cause completely untreated sewage to enter rivers and other water sources, causing them to become polluted. The consequences aren't great

Answer:
prevents blood from clotting normally due to the body's inability to form fibrin proteins.
Explanation:
Haemophilia is a genetic disorder which could be inherited and it is characterized by constant bleeding and loss of blood when injuries occur. This is as a result of the inability of the body to form fibril proteins. The fibril proteins are responsible for the production of platelets . The platelets are responsible for the clotting of blood.
This validates haemophilia being a disorder which prevent blood from clotting normally due to the body's inability to form fibrin proteins.
C . because a foreign species could compete with a native species and drive it to extinction

Drought and other extreme weather events
Lack of emergency plans
Answer:
The following can be deduced from the life history of bark beetles;
* All bark beetles life stages are spent in the phloem, internal bark, and bark, aside from when grown-ups leave the tree they created in to travel to new host trees. Bark beetles feed on the phloem of their host trees during grown-up and larval stages.
* Many bark beetles travel toward debilitated host trees, be that as it may, during environmental conditions ideal for population improvement, populaces may develop quickly and effectively assault healthy trees.
Explanation:
Bark beetles determine their name since they live and create in the bark and wood of trees and bushes. Grown-ups unearth egg displays in living bark (phloem).
Bark beetles are the most dangerous creepy insects in western coniferous woodlands. It has been assessed that 90% of insects caused tree mortality and over 60% of the complete insect caused loss of wood development in the US is because of bark beetles.
