C. speciation D. macroevolution E The primary cause for loss of biodiversity is A. predation B. parasitism C. genetic mutation D. habitat destruction E. global warming E Can instinctive behavior be modified by the environment? A. no, it is innate and cannot be changed B. yes, it changes with any experience C. yes, if the environmental influence occurs at an appropriate time E What is the environmental impact of strip mining? A. lack of trees exposes the surface of the earth, promoting runoff and loss of adjacent trees

Explanation / Answer

Step 1. B

The relatively short term changes in allele frequencies within a species or population is- Microevolution. In Macroevolution the long term changes in allele frequencies to next generation. Artificial selection- is to choose desired traits to express in population and their reproduction. Speciation- is the formation of new species in course of evolution.

Step 2 D

The primary cause of loss of biodiversity- is Habitat destruction. The Habitat destruction is caused by deforestation, overpopulation, pollution and global warming etc.
