Answers

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.

What paths do hurricanes follow?
a.) cold deep currents
b.) warm deep currents
c.) cold surface currents
d.) warm surface currents


NEED ASAP

Answers

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.

Which of the following is necessary in order for natural selection to act on a
population?

A. selective pressures that favor certain individuals
B. asexual reproduction through mitosis
C. equal chance of survival for all individuals
D. decrease in diversity through genetic drift

No dam links

Answers

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.

What is natural selection?

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.

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.

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.

Getting to know

the environmental conditions under which the virus is more active,the recognition of the local mosquito species that are dangerous in each particular area, the migration routes of involved birds, and letting people know about all the prevention measurements

are the tools that provide higher chances to avoid the fast spread of the illness.

What do you think would happen to the population of rabbits, if the population of foxes decreased?

Answers

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.
