Question
John is studying Bees. In certain closely related species of bees, he notices the proboscis (sucking appendage, like a tubular tongue) of species 1 is very long and the proboscis of species 2 is very short. Species 1 lives in moist forests and feeds primarily on flowers with a long tubular-shaped flower. Species 2 lives in open areas and feeds on small flowers with a flat landing area. When John describes the differences in the feeding behavior of the two species, it would be appropriate for him to us the word/phrase __________________________ to describe the long proboscis of species 1.

Adaptation
Gene pool of a species
Sexual species

Fishes in a group called Cichlids have colonized many different habitats within Lake Victoria in Africa. Certain Cichlid species locate food near the surface of the lake. These mostly feed on insects. Other species feed exclusively on rocky areas in the bottom of the lake. These mostly feed on plant material. The best term for this scenario is _________________________.

It must cause a change from one species to another
Genetic variation must be present in the population

Which statement clearly explains why many bacterial populations have evolved resistance to antibiotics?
If a population of bacteria is exposed to a specific antibiotic, the population will mitate daster and become resistant to that specific antibiotic
If a population of bacteria has any individuals with an allele that helps them resist being destroyed by a specific antibiotic, and if the population is exposed to this antibiotic, then the resistant individuals will have better reproduction and over generations, and the resistance allele will become more common over time
If a population of bacterial is exposed to antibiotics, the antibiotics will cause the bacteria to become resistant.
Which statement about acceptance of evolution is correct?
There is a general debate among scientists about whether evolution occurs
All religious groups reject evolution regardless of the scientific evidence
There is accepted scientific evidence that the Earth is only a few thousand years old
None of these statements are correct
Which of the following statements related to individual evolution is flase?
Individuals cannot evolve- they can oly adapt to their environments to help them live longer
Individuals do change over their lifetime, but this is called development
Natural selection requires more than one generation to occur, so individuals can’t evolve and only populations can evolve
None of these
