Diversifying selection
Diversifying or disruptive selection favours extreme phenotypes to survive that is both small and larger fish but not medium sized .
Directional selection will result in evolution of larger fish .
Since no bird predation, it will not favour smaller fish but only largerfish

Lab 11: The Witte il An Introduction to Paleontology 1. Paleontology at the Witte: Paleontology is the study of fossils. Traditionally, multiple subdisciplines can be defined. For example, Paleobotany is the study of fossil plants, Paleodimatology is the study of ancient climates, and Palynology is the study of fossil pollen and spores. Paleontology differs from Archaeologyas the former includes the study of modern humans....
QUESTION 2 Climate change is a threat to the existence of many species. Which of the following limits to natural selection hinders the adaptation of species to the new climate conditions? The developmental plans of plants and animals are too complex. They cannot cope with the warmer temperatures. Mutations happen so frequently that beneficial alleles change before natural selection can substantially increase their frequency Many species not have gene variants in their gene pool that are beneficial in higher temperatures. Climate change happens so...

From the pages 571-587 attached below.
1a) Suppose a population of guppies was infected with a
parasite. In that population a mutation results in a parasite
resistant genotype that spreads through the population through
natural selection. A subsequent mutation in the parasite results in
a genotype that is unaffected by the newly evolved resistant guppy
genotype. What is the name of the hypothesis that explains this
host parasite “arms race”.?
1b) What is this name...
Please read the article and answer about questions. You and the Law Business and law are inseparable. For B-Money, the two predictably merged when he was negotiat- ing a deal for his tracks. At other times, the merger is unpredictable, like when your business faces an unexpected auto accident, product recall, or government regulation change. In either type of situation, when business owners know the law, they can better protect themselves and sometimes even avoid the problems completely. This chapter...
