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

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

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

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

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

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

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

What would happen if a breeding pair of finches were 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 in the Galapagos Islands require food to eat and water to drink.

Which characteristic would a biologist consider most important in determining which among a population of guppies was the most suitable?

Fitness is a term often used by biologists to explain the evolutionary success of certain organisms. What characteristic would a biologist consider most important in determining which guppies were "most suitable" in a particular environment? The ones with the brightest colors as they can attract more mates.

What did Darwin say about finches?

Darwin noted that frugivorous finches had parrot-like beaks, and that insect-eating finches had narrow, curious beaks. He wrote: "One might indeed imagine that from an original want [scarcity] of birds a species had been taken and modified for various purposes."

Why do the largest and strongest individuals in a population not always produce the most offspring?

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

What would happen if a breeding pair of finches were placed on an island under ideal conditions with no predator group of response choices, would the finch population remain small because birds only have enough babies to replace themselves as the finch population would?

Why would a finch population living on an island have a higher species type than a finch?

The sea finches have higher gene flow. Why would a finch population living on an island have a higher species type than a finch population living in a large forest in North America? The finches have higher genetic drift.

Which of the following is not necessary for natural selection to work?

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 take place. Natural selection cannot act on variation that is due solely to environmental conditions.

Where does the strongest evidence of change over a longer period come from?

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

What four factors influence 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 within a species due to mutation and sexual reproduction, (3) competition for an environment's limited supply of the resources that the individual needs to…

When do finches need food and water to survive?

When food and water are scarce, some birds may be unable to get what they need to survive the population of finches that have lived on the island for years, the population remains stable, with fluctuations The population of finches, what is the primary changes that occur over time, the proportion of finches have different traits w/i population change

How are finches affected in the Galapagos Islands?

Finch Population Will Increase Dramatically Finches in the Galapagos Islands require food and water When food and water are scarce, some birds may not be able to get what they need to survive the population of finches that have lived on the island for years, the population remains stable, with fluctuations

How does the population of finches change over time?

population remains stable, w/ fluctuations The finch population, what are primary changes that occur over time, the proportion of finches with different traits w/in the population changes depending on beak size and shape, some finches get nectar from flowers/pits from bark/small seeds / large nuts. Relationship between finches & food supply

What kind of finches live on an island?

the population of finches has lived on the island for years the population remains stable, with fluctuations The finch population, what are the primary changes that occur over time, the proportion of finches with different characteristics w/in the population changes depending on beak size and shape, some finches get nectar from flowers / grubs from bark / small seeds / large nuts.
