Eutrophication is often caused by excess limiting-nutrient runoff from agricultural fields into aquatic ecosystems. This process results in massive algal blooms that eventually die and decompose, ultimately depleting the dissolved oxygen, killing large numbers of fish and other aquatic organisms. Predict which of the following human actions would best address the problem of eutrophication near agricultural areas?

#Unit 9. Diversity of Life Forms
  1. After each eutrophication event, remove the dead fish and invertebrates to place on agricultural fields instead of fertilizer.

  2. Determine which limiting nutrient is responsible for the algal bloom, and use other fertilizers to apply to crops.

  3. Remove the algae before it dies and decomposes to prevent eutrophication from occurring.
  4. Determine critical nutrient loads required for certain crops, and do not exceed this amount during fertilizer application.

In an adaptive radiation, numerous related lineages arise in a relatively short time and evolve in many different directions as they adapt to different habitats or ways of life. Radiation, rather than directional trends, is perhaps the most common pattern of long-term evolution. Which statements is not true for adaptive radiation?

CCR5 that plays a role in inflammatory response. Unfortunately, this protein is also a key to human immunodeficiency virus (HIV) infection. The virus binds to a loop of the CCR5 protein and then enters the cell. Some people have an allele called Δ32 at the CCR5 locus in which 32 bp are deleted. The missing part of the gene codes for the loop in the protein to which the virus attaches. Which statements is true for CCR5?
