Answer:

directional selection

Explanation:

Directional selection is a type of natural selection where individuals exhibiting an extreme phenotype for a given trait are favored over the mean or other extreme phenotype. This type of selection can lead to drastic and fast changes in allele frequencies between generations in a population, being particularly important in speciation processes. Directional selection is common under environmental changing conditions (e.g., weather, climate, food availability, etc) or when individuals migrate to other regions in order to adapt to new environmental pressures.

Answer:

I DON'T SEE OPTIONS, BUT HERE IS MY GUESS

It is for support.

Explanation:

Plant cells lack necessary support without their cell walls. An animal cells usually have skeleton of some sort to support it, so they don't need cell walls. Plants, on the other hand, don't have skeletons.

Answer:

Warm surface currents

Explanation:

The path of a hurricane greatly depends upon the wind belt in which it is located. Hurricanes draw their energy from the warm surface water of the tropics, which explains why hurricanes dissipate rapidly once they move over cold water or large landmasses.

The karyotype of the bottlenosed dolphin and the pilot whale have been described and compared from a karyological evolutionary point of view. Both species have 44 chromosomes and the two chromosome complements are strikingly similar.

Explanation:

Complete question:

Corvids are a large family of birds that includes many species of ravens, jays, crows, and magpies. It was recently discovered that numerous birds in this family are an important vector for the West Nile virus because infected mosquitoes may pass the virus to these birds. Not to mention other species: there are over 35 species crows across the world alone and more than 3,500 species of mosquitoes across 41 different genera. Taken together, these facts demonstrate that it is critical that global societies and scientists

A) use more detailed common names to identify species,such as the "violet crow" or the "American crow."

B) use the genus and specific epithet scientific name to identify taxa.

C) use DNA sequences when referring to a particular species.

D) track diseases like West Nile virus using remote sensing technology on birds to help predict illness spread.

E) invoke higher levels of the classification system, such as kingdom and domain, when referring to a species.

Answer:

D) track diseases like West Nile virus using remote sensing technology on birds to help predict illness spread.  

Explanation:    

The West Nile virus affects many animals, among which there are many bird species. Birds turn to be one of the most important ones, not only because the virus keeps on nature through the cycle mosquito-bird-mosquito, but also because they act as dispersal organisms that carry the virus through long distances.

Due to its mortality and the many organisms it affects, it becomes a need to track the affected birds by the West Nile virus to make prevention through predictions about the distribution area and the periods in which it is more feasible for the virus to attack. It is particularly interesting to apply these tracking technologies to birds. They are severely affected by the West Nile virus and might carry and spread it faster in broad areas due to migration.

Answer:

B

Explanation:

A population of mosquitoes is exposed to the pesticide DDT for several generations. At the end of that time, most individuals in the population are resistant to DDT and the most likely reason is that  some individuals in the original population had the mutations that led to resistance. Option B is correct.

Mutation is the change in which there is slight change in the genome sequence of a DNA or RNA along with the gene. The mutation lead to various types to adaptations along with the diseases.        

Resistance is the condition when the species on the multiple exposures develop certain kind of adaptations to it and these traits are sometime inherited sometimes not inherited.

Mutations are friendly as well where sometimes a disease causing mutation can be altered with the further mutation in it.

Therefore on the multiple exposure it led to condition of resistance in  the species.

Answer:

I don't know

sorry I didn't understand anything

Answer:

A

Explanation:

Natural selection occurs when an environment makes organisms with certain traits more likely to survive and reproduce.

Asexual reproduction results in no genetic variation (meaning differences in traits, also called divserity). Genetic variation must be present for certain organisms to be better suited to their environment, because in its absence all organisms share the same traits. This rules out B, C, and D. I hope this helps :)

Selective pressures that favor certain individuals are necessary in order for natural selection to act on a population. Therefore, option (A) is correct.

The process by which organisms are able to pass on the favorable qualities they possess to their offspring is known as natural selection. Organisms that are better able to adapt to their surroundings have a greater chance of surviving and reproducing in that environment. As a consequence of this, advantageous characteristics become more prevalent over time, whereas undesirable traits become less prevalent, resulting in a change in the genetic make-up of a population.

Natural selection can be influenced by a variety of environmental factors, including predation, competition for resources, and shifts in climate. It is a fundamental mechanism of evolution and contributes to our understanding of the diversity of life on Earth as well as the various ways in which different species have adapted to their surroundings.

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Answer:

the population of rabbits might increase

Explanation:

With less predators to eat them, the rabbit population will likely go up if the fox population decreases; assuming there are favorable factors such as plenty of food and habitat for the rabbits. At some point, there is a maximum limit to the number of rabbits that a certain location can hold. Once this limit is reached, (some of) the rabbits will migrate elsewhere or unfortunately die off.

As the rabbit population increases, the fox population may rebound and start increasing again. This is due to more food being available to the smaller amount of foxes, and there is less competition for food. So the rebounding fox population will likely bring down the rabbit population to a point where food will get more scarce for the foxes. This cycle repeats itself where one population increases while the other decreases, and vice versa. They are very strongly linked together. It's also possible that both will increase together if environmental factors are favorable, but they could easily decrease together if a habitat is being destroyed for instance. It will depend on the circumstance.
