Which of the following best describes natural selection?

Only the largest and strongest organisms survive.

Random genes in a population always result in better characteristics in offspring.

Some organisms choose to live and some die in each generation.

The best adapted individuals survive and reproduce, contributing the most to the next

generation.

During the industrial revolution in England, factories produced black as that covered the trucks and branches of the white aspen trees. At the same time, the number of white moths that lived on the trees decreased.
Based on the moth example above, which statement is true?

The black moths were adapted and most fit so they survive and reproduce

The birds stopped eating moths altogether and found another food source

All moths were unable to reproduce and eventually became extinct

The white moths were able to survive and reproduce better than the black moths

Blue flying fish live in the upper layers of the ocean. Blue flying fish have enlarged pectoral fins that enable them to glide for 400 meters above the ocean surface and appear to fly.
Which statement best describes how natural selection led to enlarged pectoral fins in blue flying fish?

Fish were able to glide out of the ocean and into other bodies of water to mate with other species.

Fish were able to live both on land and in the water as a result of their larger pectoral fins.

Fish with enlarged pectoral fins were able to glide out of the ocean to escape predators, increasing their fitness.

Fish changed their DNA to express enlarged pectoral fins, changing the allele frequency of the population.

A population of Escherichia coli (E. coli) bacteria is exposed to a new antibiotic. Most of the bacteria are killed by the antibiotic, but a few survive. After examining the survivors, scientists discover that a random change in the DNA of one bacterium has enabled it to resist the effects of the antibiotic. This bacterium reproduces, and over several generations, more and more bacteria in the population show resistance to the antibiotic.

The ability for E. coli to resist antibiotics is due toin the population.

The graph below shows the average speed of rabbits. The data was collected between 1965 and 1967, after wolves were introduced back into the area.
What is the change in the phenotypic distribution?

An increase in food availability lead to the rabbit population increasing

The percentage of slower rabbits increased due to introduction of wolves

A decrease in fitness that increased reproductive success

The percentage of faster increased due to the introduction of wolves

The diagram below shows different beak shapes of finches. In the ancestral species of finches, beak size was much larger than in three living species of finches.
Which question would BEST help determine whether the change beak size and shape of these finches was influenced by natural selection?

Is the beak shape of male finches similar to that of female finches, and which bird has a longer body length?

What is the relationship between feather color and beak shape of finches?

How does the beak shape of finches change from generation to generation in response to food sources?

Did the ancestral finch have a larger wing span than living finches?

The rainbow trout is a freshwater fish that lives in the rivers of Minnesota. A 5 pound trout is capable of laying up to 6,000 eggs at once.
Many of these embryos will be eaten by predators or will freeze in the arctic water before they can reach adulthood. Only 3% of the eggs will actually hatch and reach adulthood.
Why does the rainbow trout use energy to lay up to 6,000 eggs if most of them will not survive?

Producing more offspring increases the probability that some will survive and reproduce

Producing more offspring increases competition between other organisms who eat the same food

Producing more offspring increases the probability of developing beneficial mutations in the population

Producing more offspring increases the probability that they will evolve into a new species.

Consider the breeding of two types of corn: one that has high yield but is non-resistant to a certain pest, and another that is resistant to that pest but has a lower yield.

null

During the process of pollination (reproduction), the pollen from one corn plant fertilizes the ovule of another. The resulting hybrid plants will have both high yield and pest resistance.

The evolution mechanism that BEST supports creating a new hybrid plant is .

Which scenario best describes gene flow?

Ɛhia

1

Why is gene flow important?

It eliminates harmful genes from these populations, making them better at surviving.

It creates identical copies of cells maintaining uniformity.

It forces the cells to rely on a single source of nutrients, which prevents other species from outcompeting them.

It increases genetic variation, which increases their ability to survive.

A population of insects is exposed to a pesticide. Some insects survive because they inherit a combination of genes from their parents that allows them to detoxify the pesticide. Over several generations, more insects survive and reproduce, passing on this beneficial genetic mix. How might this change the makeup of the population over time?

The combination of genes is due to over time.

Cross-pollination occurs when pollinators (such as the common honey bee) transfers pollen from one flower to another.
The cross-pollination of flowers from different populations of the same species will most likely result in...

gene flow as new alleles are introduced

evolution of a different species as alleles mix

hybrid sterility as gametes from different individuals are incompatible

a decrease of genetic variation among individuals

In the Bottleneck Effect, an event will suddenly drastically reduce the size of a population, changing the allele frequency at random. Examples include volcanic eruptions, earthquakes, floods, and hunting.

In the original population, the alleles had the highest phenotypic distribution.

As a result of the bottleneck effect, variation

The population would increase because the disease does not affect the white and blue iguanas.

The population would stay the same because the disease cannot kill iguanas.

The population would decrease because there are no more iguanas with the gene to protect against disease.

In the Bottleneck Effect, an event will suddenly drastically reduce the size of a population, changing the allele frequency at random. Examples include volcanic eruptions, earthquakes, floods, and hunting.

Remember that mutations are changes in the nitrogen base sequence of DNA, which then change amino acid sequences that build proteins. When mutations occur, new phenotypes are added to the gene pool. These mutations can either be good or bad, depending on the environment.
