Resistance traits will be most prevalent, however, in bacteria that are chronically exposed to antibiotic drugs. D. Resistance traits are produced because antibiotic drugs cause mutations in bacterial cells. The resistance traits only occur in the presence of antibiotics.
Humans share several features with salamanders. Certain genes and proteins are nearly identical between the two species; both species have four limbs with a similar skeletal structure; the species' early embryos are very similar; and where the salamander has a functional tail, humans have a vestigial tailbone.
The forelimbs (or possibly hind limbs) will be used for the new purpose of flight. This new function will arise through many gradual steps, and there will be aspects of the wing that reflect its history and are not perfectly suited for flight. C.
After a copper smelter begins operation, local downwind populations of plants begin to adapt to the resulting air pollution. Scientists document, for example, that the acid tolerance of several plant species has increased significantly in the polluted area. This is an example of. A. directional selection.
A. During the 1950s, a scientist named Lysenko tried to solve the food shortages in the Soviet Union by breeding wheat that could grow in Siberia. He theorized that if individual wheat plants were exposed to cold, they would develop additional cold tolerance and pass it to their offspring.
B. The forelimbs are similar because of adaptation through the process of natural selection. C. The forelimbs are similar because there is only one workable way to construct a useful arm, leg, or wing.
As the large lakes dried up, small groups of pupfish remained in springs and pools fed by groundwater seepage. Now, although many of these small springs still have pupfish, each population, through evolution, has become very different from populations of pupfish in other springs.
In 1859, Charles Darwin wrote, "The affinities of all the beings of the same class have sometimes been represented by a great tree...
There is a group of small fish living in a lake with a sandy bottom. Most of the fish are light brown, but about 10% are mottled. These fish are normally prey for large birds that live on the shore. A construction company dumps a load of gravel in the bottom of the lake, giving it a mottled appearance.
Natural selection starts with the creation of new alleles that are directed toward improving an organism's fitness. Natural selection can be observed working in organisms alive today. Natural selection starts with the creation of new alleles that are directed toward improving an organism's fitness.
The population is in Hardy-Weinberg equilibrium because the number of B alleles is equal to the number of b alleles.
Milkweed plants wanted the butterflies to ingest the chemical so they would no longer feed on the plant, but the butterflies fooled the milkweed by storing the toxic chemicals. Butterflies developed a mutation that led them to be able to store the chemical because they needed to avoid being eaten.
Some butterflies can ingest toxic chemicals from the milkweed plants they feed on and then can store those chemicals in their body. Because toxins stored in the butterflies are toxic to birds, the birds avoid eating the butterflies.
They evolve through genetic drift and other chance processes. They evolve to be more useful by taking on new functions. They evolve through genetic drift and other chance processes. In populations of the greater prairie chicken in Illinois, genetic diversity was. lost through genetic drift and restored by gene flow.
p will fluctuate rapidly and randomly because of genetic drift. p will neither increase nor decrease; it will remain more or less constant under the conditions described. p will increase; the dominant allele will eventually take over and become most common in the population. p will decrease because of genetic drift.
Adaptation results when cold temperatures cause mutations for longer fur. A population that has an increase in frequency of alleles for thicker fur has become adapted to the cold. An individual that has learned how to survive cold winters has become adapted to the cold.
