Animal Diversity
Nematodes are commonly known as roundworms. They are free-living, very tiny organisms. They have an elongated and tubular body. These organisms have a nervous system and are mostly act as parasites to both animals and plants.
Platyhelminthes
Platyhelminthes are also known as "flatworms" because as they are dorsoventrally flattened from head to tail. They are invertebrate, soft-bodied, acoelomate, unsegmented and have bilateral symmetry.
Step by step
Solved in 2 steps
- Which reproductive isolating mechanism(s) might be operating in each situation? There may be more than one possible answer for each. a.Different species of songbirds inhabit the same forest yet do not interbreed. b.Salmon and trout populations breed in the same streams in British Columbia, during the same period. c.A gardener has two closely related plant species. One blooms in the summer; while the other blooms in the spring.How do hatcheries (i.e. farmed salmon) impact wild salmon population genetics? A: Increase species variability between different populations B: Decrease the resilience of wild populations C: Decrease mixing between different populations D: Overcrowd streams when they return to where they were spawnedA group of 50 men and 50 women establish a colony ona remote island. After 50 generations of random mating,how frequent would a recessive trait be if it were at afrequency of 1/500 back on the mainland? The population remains the same size over the 50 generations, andthe trait has no effect on fitness.
- If gene flow between two populations stops, which of the following could occur given enough time? a. speciation b. the population each gain unique alleles c. the timing of reproduction changes ending their ability to interbreed d. frequencies of alleles shift in different ways e. these are all things that could occur if gene flow between two populations of one species ended, given enough timeA farmer is raising rabbits. The average body weight in his population ofrabbits is 3 kg. The farmer selects the 10 largest rabbits in his population,whose average body weight is 4 kg, and interbreeds them. If the narrowsenseheritability of body weight in the rabbit population is 0.7, what is theexpected body weight among the offspring of the selected rabbits?Which variable increases the likelihood of allopatric speciation taking place more quickly? a. lower rate of mutation b. longer distance between divided groups c. increased instances of hybrid formation d. equivalent numbers of individuals in each population
- Which of the following decreases genetic variation in a population? a)natural selection b)mutation c)gene flow d)meiosis e) A and C only (Option E is said to be incorrect)Which of the following traits is more associated with an Opportunistic (Equilibrial) species? Which of the following traits is more associated with an Opportunistic (Equilibrial) species? A. Short maturation time B. Producing offspring at many different times over the course of life C. Producing a lot of eggs at one time D. High juvenile mortality E. High level of parental careIf these conditions held constant – what would the expected heterozygosity be in thepopulation today (2018 to deal with a clean integer value for generations)?1b. In 1884 the population had grown to 106 when disaster struck the island. Of the 19 adult menon the island, 15 were in the same fishing boat that capsized, leaving only 4 adult men alive onthe island. These desperate times may have changed the sex ratio of the breeding population onthe island. Let’s say that now, each man fathered children with an average of 1.5 differentwomen (male:female ratio of 1:1.5). If we start back with a heterozygosity of 0.5 from this point,given the effective population size on Tristan da Cunha, what is the expected heterozygosity inthe current population 7 generations later?1c. The scenarios described in 1a and 1b are examples of which two evolutionary phenomena,respectively?
- In which situation will populations experience gene flow? A)hybridization between two populations of ground beetles B)natural-selection pressures between two populations of dragonflies C)mate competition between two populations of red-legged grasshoppers D)intersecting migration routes between two populations of monarch butterflies9) This chart shows the beak length of a population of finches in the Galapagos. The island was faced with a five year drought that made it difficult for birds to get water. If natural selection occurs, how would you predict the bird beak lengths to change? A) Only those with shorter beaks would survive. B) The population would not really change much. C) Only those with the longest beaks would survive. D) Those with medium-long beaks would increase most. Not GradedWhich of the following statement(s) is/are true? Select the best overall answer. a. Kenward et al. reported that for each paired bird with eggs, there were three floaters in a European population of Common Buzzards b. in Complete Migration, there is predictable, seasonal movement of individuals between a breeding range and a non-breeding range (and back again) with no geographic overlap of these two ranges. The Broad-winged Hawk is an example of a species that exhibits Complete Migration. c. A paper by Bednarz et al. published in 1990, demonstrated with observational tallies of migrating raptor species that populations declined in migratory counts during the DDT era. d. all of the above e. only b and c
