after a bottleneck event. the population of rabbits in an area has signifcantly decreased. A decade ater, the populatipn of the rabbits recovers to its orginal numbers. Which statment is correct about the rabbits?

They are lily to survive evionmental changes because they surivved the bottleneck event

They are less likely to survive environmental changes because of the bottleneck event

They are more likely to survive environmental changes because of the bottleneck event

They are as likely to survive evironemtnal changes because their population has recovered

I'm sorry, I don't understand what you mean by "kk". Could you please provide more context or clarify what you're trying to say?

False. Inbreeding increases the chances of genetic defects due to the inheritance of two copies of the same defective gene from both parents. This can result in health problems or reduced fertility, and may decrease the survival and reproductive success of the offspring.

The statement that accurately describes the relationship between variation and fitness is "variations can lead to either an increase or decrease in fitness." Variations in traits may result in an individual having either higher or lower fitness compared to others in its population depending on the environment. Some traits may enhance an organism's ability to survive and reproduce, which results in higher fitness, while other traits may be disadvantageous, resulting in lower fitness. Therefore, variations can either increase or decrease fitness depending on their effects on an organism's reproductive success.

The most likely scenario is that the proportion of white-furred rabbits in the population will decline. This is because the shorter winter will likely cause less snow and less white background in the environment, which would make the white-furred rabbits less well-camouflaged and more vulnerable to predators. Brown-furred rabbits, being better camouflaged in the new environment, would have a higher chance of survival and reproductive success. Therefore, over time, the proportion of brown-furred rabbits in the population is likely to increase while the proportion of white-furred rabbits declines.

The trait that is an advantage is called an adaptation.

The statement that is correct about the rabbits that have experienced a bottleneck event is "They are less likely to survive environmental changes because of the bottleneck event." During a bottleneck event, a significant portion of the population dies or is prevented from reproducing, causing a loss of genetic diversity in the population. This can reduce the genetic variation that is essential for populations to adapt to environmental changes. Therefore, population recovery following a bottleneck event does not necessarily restore genetic diversity, and the resulting population may be more vulnerable to environmental changes due to reduced genetic variation.

The statement that is correct about the population of peppered moths in modern Britain is "The dark-colored moths are most common due to anti-pollution regulations." Prior to industrialization, the light-colored peppered moths were more common in Britain because they were better camouflaged against the light-colored tree bark that covered most trees in the area. However, during the Industrial Revolution, air pollution killed the lichen on trees and darkened the bark. The dark-colored moths became better camouflaged against this darkened tree bark, giving them a survival advantage, which increased their proportion in the population. The implementation of anti-pollution regulations led to a decrease in air pollution and contributed to the return of lighter-colored tree bark. However, the dark-colored moths are still prevalent as they have not gone extinct.
