Genetic variation is brought about by mutation, genetic recombination, and gene flow in a population. Therefore, option (C) is correct.
The differences in DNA sequences that exist between individuals within the same group are referred to as genetic variation. Both germ cells, which include sperm and eggs, and somatic cells, which include all other types of cells, are subject to variation.
One source of genetic variation is mutations, which can be defined as any alteration in the sequence of genes found in DNA. Gene flow, which can be defined as the movement of genes across various groups of organisms, is still another source. The final cause of genetic diversity is sexual reproduction, which results in the formation of new gene combinations and can be a consequence of sexual reproduction.

The wolf population is naturally controlled through their ecological role as a keystone species. Their presence impacts other animal populations and vegetation, influencing the overall biodiversity of an ecosystem. Additionally, their social and territorial behaviors also play a role in their population control.
The wolf population is naturally controlled in the environment through a combination of factors, most notably their role as a keystone species. For instance, their reintroduction into Yellowstone National Park in 1995 drastically changed the local ecosystem. The wolves suppress the populations of elk and coyotes, allowing for increased vegetation and subsequently higher diversity in the park.
This change in grazing behavior of elk resulted in willow and cottonwood seedlings growing in areas previously grazed barren, reducing erosion, providing shading to creeks and improving fish habitats. Other animals, like beavers, also benefited from these changes in the habitat. Furthermore, the dynamics of wolves in a pack, their hierarchical social structure, impacts their proliferation and territorial behavior which also influences their population numbers in the wild.
Therefore, wolves, like other animal populations, are regulated naturally by a complex web of ecological interactions and processes.

Answer: The scientific method is cyclic.
Explanation: Scientific methods is the systematic way of using knowledge , hypothesis , observation , theories and experiments , to give us understanding for the questions.
Scientific method is always cyclic as it involves several steps. Cyclic way give us better understanding about facts and whole phenomena.
Answer:
Cyclic
Explanation:
Scientific method comprises of various complex procedures or cycle. Scientific method involves a lot of people and ideas usually generate more and new ideas. It doesn’t usually follow a set guideline or step.
It involves raising up of more questions as more ideas are discovered . It makes sure the analysis and procedure is a very thorough one with no issue.
