What would happen if a mating pair of guppies was placed in a large pond?

high number of matings with many different females. happen if a mating pair of guppies were placed in a large pond? The guppy population will continue to rapidly grow in size.

What is most likely to happen to the lizards of a certain species when the food supply is limited?

Lizards eat a variety of insects and plants. What do you think happens among the lizards of a certain species when the food supply is limited? The lizards least successful in the competition for food are likely to die of starvation and malnutrition. Populations of lizards are made up of hundreds of individual lizards.

How did the different types of beaks first appear in the finches?

How did the different beak types first arise in the Galapagos finches? a) The changes in the finches’ beak size and shape occurred because of their need to be able to eat different kinds of food to survive.

What would happen if a breeding pair of finches was placed on an island under ideal conditions with no predators group of answer choices?

What would happen if a breeding pair of finches was placed on an island under ideal conditions with no predators and unlimited food so that all individuals survived? the finch population would increase dramatically. Finches on the Galapagos Islands require food to eat and water to drink.

Which feature would a biologist consider to be most important in determining which from a population of guppies which were the most fit?

Fitness is a term often used by biologists to explain the evolutionary success of certain organisms. Which feature would a biologist consider to be most important in determining which guppies were the “most fit” in a particular environment? Those with the brightest colors since they can attract more mates.

What did Darwin say about finches?

Darwin noticed that fruit-eating finches had parrot-like beaks, and that finches that ate insects had narrow, prying beaks. He wrote: “One might really fancy that from an original paucity [scarcity] of birds one species had been taken and modified for different ends.”

Why don t the biggest and strongest individuals in a population always produce the most offspring?

Individuals with mutations that are disadvantageous won’t produce many offspring, but individuals with beneficial mutations will produce many offspring. The beneficial mutations will thus increase in frequency through selection. The biggest and strongest individuals always have higher fitness.

What would happen if a breeding pair of finches was placed on an island under ideal conditions with no predators group of answer choices the finch population would stay small because birds only have enough babies to replace themselves the finch population would?

Why would a finch population that lives on an island have a higher rate of speciation than a finch?

The island finches have higher gene flow. Why would a finch population that lives on an island have a higher rate of speciation than a finch population that lived in a large forest in North America? The island finches have higher genetic drift.

Which of the following is not required for natural selection to operate?

Answer: Only when variation among organisms is inherited from the previous generation, i.e. it has a genetic basis, will natural selection be able to occur. Natural selection cannot act on variation that is due purely to environmental conditions.

Where does the strongest evidence for change over a long period of time come from?

Today, scientists can compare their DNA. Similar DNA sequences are the strongest evidence for evolution from a common ancestor.

What four factors affect Darwin’s evolution?

Evolution is a consequence of the interaction of four factors: (1) the potential for a species to increase in number, (2) the genetic variation of individuals in a species due to mutation and sexual reproduction, (3) competition for an environment’s limited supply of the resources that individuals need in order to …
