What are the two main factors that cause individuals of the same species to appear different?
Genetic variation and environmental factors are the two main factors that cause individuals of the same species to appear different. Genetic variation results from differences in DNA sequences passed down through generations, while environmental factors such as diet, climate, and exposure to sunlight can also influence physical appearance.
What is an environmental variation that cigarettes cause?

What factors cause variation in the atmosheric elements?

What does 'environmental variation' mean?
'Environmental variation' refers to the differences in environmental conditions such as temperature, humidity, or nutrient availability within a specific ecosystem or location. This variation can have significant impacts on the growth, behavior, and reproduction of organisms in that environment. Factors contributing to environmental variation can include natural processes, human activities, and climate change.
How do genetic variation and environmental factors influence evolution?
Genetic variation drives evolution by providing the raw material for natural selection to act upon, allowing organisms to adapt to changing environments. Environmental factors can influence which traits are favored, shaping the direction of evolution. Together, genetic variation and environmental factors contribute to the diversity of life on Earth through the process of evolution.
What factors could be important for a species to evolve by natural selection?
Environmental change and variation :)
What are the three types of variation?
The three types of variation are genetic variation, environmental variation, and genotype-environment interaction. Genetic variation refers to differences in DNA sequences among individuals, while environmental variation is differences in traits caused by external factors. Genotype-environment interaction occurs when the effect of genes on traits depends on the environment.
What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
Is the length of a hair an example of inherited or enviromental variation?
The length of a hair is an example of inherited variation influenced by genetics. While environmental factors like diet and stress can affect hair health, the actual length of hair is primarily determined by genetic factors passed down from parents.
Is Scars Inherited Variation or Environmental?
Scars are a result of both inherited variation and environmental factors. Genetic predisposition can determine how easily a person scars, while factors such as the type and severity of injury, age, and skin color also play a role in how a scar forms.
What is the definition of limiting factor?
it is an environmental factor that causes a population to decrease.
