Question
the number of different types of organisms found on earth is a result of? d. the formation combinations of o alle new of alleles durine as ID: A Name 63. The soapberry bugs in the figure below adapted to a change in food source in as fast as 30 years. For shown evolution to occur this quickly These soapberry bugs rapidly evolved short beaks, enabling them to feed on the seeds of a new host plant. a. alleles for shorter beaks must have been present in the soapberry bug population before its food source changed. gs must have mutated their beak length genes when they ran out of food. c, the life cycle of the soapberry bug (time from egg hatching to reproductive age) must be very long. d soapberry bugs must have had several other food sources besides the fruit they normally 64. For the quality of an adaptation to improve over time, must already exist within the population. a. genetic limitations c. speciation b, genetic variation d. ecological trade-offs 65. If population lacks genetic variation, a. it may not be able to evolve as the environment changes. b. it is more likely to undergo gene flow. c, reproductive isolation is unlikely. d. the rate of speciation may increase. 66 Which of the following terms describes all organisms on Earth plus their environments? a. biosphere b. ecosystem c. habitat 67. Species species a. can that are accidentally introduced to new geographic regions become serious pests. b, usually quickly die out. c. can form hybrids with native species. d, all of the aboveExplanation / Answer
63. ANS: b. The soapberry bugs have must mutated their beaks length genes, when they ran out of food.
Beak size variation:
In South Florida soapberry bugs feed on balloon vine tree with large fruits, longer beak present in them.
In North Florida soapberry bugs feed on golden rain tree with small fruits, they have shorter beaks.
64. ANS: b. Genetic variance
Genetic variation: The genetic variation can leads to phenotype variation in a population. The pheno type variation is necessary for natural selection.
65. ANS: a. it may not be able to evolve as the environmental changes.
The process of evolution never occurs in genetic variation absent population.
66. ANS: b. Ecosystem
Ecosystem: It explains the interactions between the population which present in the community and the communities physical surroundings or abiotic factors.
67. ANS: a. can became serious pests.
Accidentally introduced (unintentional introduction) means a species that are transported as a byproduct of movement of other goods. Invasive species can alter the entire ecosystem.
Ex: European wild rabbit is invasive in Australia.
Brown tree snake native in Australia and Indonesia is invasive in Hawaii.
Q: The number of different types of organisms found on earth is a result of?
ANS: The number of different types of organisms found on earth is a result of evolution. In this due to the environmental adaptations the genetic variations was taken placed among the population. It leads to forming a new species on earth.
