Why might it be hard to restore a wildlife population using custodial management?
Answers
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.
What is the process of evolution?Evolution is the scientific theory that explains that "a change in the characteristics of biological populations over next generations. According to scientists RNA is the first existing molecule on earth that replicate by itself and the process of evolution lead to advanced forms of life.
The restoration of wildlife population under the custodial management is very hard because the wildlife animals are very dangerous to handle and they can harm the normal population.These characteristics are easily trasffered from one generation to other generation.

The three pillars of Darwin's theory of evolution are genetic variety, fitness, and adaptation. Overproduction and competition are other crucial components of this process.
What Darwin's theory of evolution by natural selection?Charles Darwin's theory of evolution is known as natural selection. Due to the limited supply of resources in nature, animals have inherited traits that aid in both survival and reproduction.
Typically, produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.
Natural populations exhibit variation, and every population has more offspring than the environment can support. The result of this Overproduction is that those people who have the highest level of environmental genetic fitness will have offspring who are better able to compete in that environment.
Therefore, Genetic variation, fitness, and adaption are all factors in Darwin's theory of evolution.Overproduction and competition are other crucial components of this process.

B. Have long wavelengths.
C. Travel at high speeds.
D. Have short wavelengths.
Answers
Answer:
Its A
Explanation:
Its A =Have high amplitudes
Low-frequency waves have long wavelengths. Therefore, option B is correct.
What are waves?
Waves are a type of disturbance that travels through a medium or space, transferring energy without transferring matter. Waves can take many forms, including sound waves, light waves, water waves, and electromagnetic waves.
Waves are characterized by a number of properties, including wavelength, frequency, amplitude, and velocity. Wavelength is the distance between two consecutive peaks or troughs in a wave, while frequency is the number of wave cycles that occur per unit of time. Amplitude is the height of the wave, and velocity is the speed at which the wave travels through the medium.
Low-frequency waves have longer wavelengths, which means that they have fewer cycles per second (measured in hertz) and take more time to complete one full cycle. Therefore, option B is correct.
