Problem: Biodiversity:

Endemic species can be threatened with extinction through the process of genetic pollution, i.e. uncontrolled hybridization, introgression and genetic swamping. Genetic pollution leads to homogenization or replacement of local genomes as a result of either a numerical and/or fitness advantage of an introduced species. Hybridization and introgression are side-effects of introduction and invasion. These phenomena can be especially detrimental to rare species that come into contact with more abundant ones. The abundant species can interbreed with the rare species, swamping its gene pool. This problem is not always apparent from morphological (outward appearance) observations alone. Some degree of gene flow is normal adaptation, and not all gene and genotype constellations can be preserved. However, hybridization with or without introgression may, nevertheless, threaten a rare species' existence.

What is another name for interbreeding?

Question: Sub- and quotient groups are related in the following way: a subset H of G can be seen as an injective map H → G, i.e. any element of the target has at most one element that maps to it. The counterpart to injective maps are surjective maps (every element of the target is mapped onto), such as the canonical map G → G / N.y[›] Interpreting subgroup and quotients in light of these homomorphisms emphasizes the structural concept inherent to these definitions alluded to in the introduction. In general, homomorphisms are neither injective nor surjective. Kernel and image of group homomorphisms and the first isomorphism theorem address this phenomenon.
Is there an answer to this question: What is an example of a surjective map?

Answer: canonical map


Question: Agriculture is a relatively small component of the state's economy and varies greatly due to the varying climate across the state. The state ranked first in Mexico for the production of the following crops: oats, chile verde, cotton, apples, pecans, and membrillo. The state has an important dairy industry with large milk processors throughout the state. Delicias is home to Alpura, the second-largest dairy company in Mexico. The state has a large logging industry ranking second in oak and third in pine in Mexico. The mining industry is a small but continues to produce large amounts of minerals. The state ranked first place in the country for the production of lead with 53,169 metric tons. Chihuahua ranked second in Mexico for zinc at 150,211 metric tons, silver at 580,271 kg, and gold at 15,221.8 kg.
Is there an answer to this question: Agriculture varies across the state because of the variation in what?

Answer:
climate
