Answer:
Controlling the predator population, wolves.
Explanation:
The method followed for the little smoky herd protection was to control their habitat and the population of the predators in the said habitat, which were wolves.
If I recommend the same method as the best way to protect the selkirk caribou, then i would be suggesting controlling the population of the predators in the area, which are mostly wolves, and in this way protecting the population of the selkirk caribou.
I hope this answer helps.
The answer is; D
Carbon dioxide and methane are potent greenhouse gases. They cause heating of the lower atmosphere, by trapping sunlight, that results to climate change. Due to the higher melting and boiling temperatures of phosphorus, it is rare that it occurs as gas in room temperatures. Phosphorus, therefore, does not pose a great threat of climate change.
Answer:
The natural selection on polygenic traits affects selection.
Explanation:
The natural selection process allows changes in frequencies of alleles in a character that is determined by single gene. The polygenic characteristics are disproportionately affected by natural selection as natural selection affect the phenotype distribution.
This occurs in three ways that are disruptive selection, stabilizing and directional selection.
Answer:
e) Invertebrates lack a nervous system
Explanation:
One of the main characteristics of invertebrates is that they don't have a backbone. Backbones belong to the skeletal system. A totally different story is the nervous system which runs inside the backbone. Although the more complex nervous systems appear in vertebrates the simply fact of having eyes like crabs or insects implies having a nervous system that can control them.
