Answer 1

Answer:

d. Populations have the potential to grow to very large numbers

Explanation:

Natural selection and artificial selection both cause changes in animals and plants. However, the natural selection happens naturally, but selective breeding (artificial selection) only occurs by humans interventions. Natural selection has four components:

• Variation.
• Inheritance.
• High rate of population growth. In artificial selection, selection itself diminishes the probability of adaptation. But in natural selection populations have more offspring and have more chance to alive in struggling for local resources.
• Differential survival and reproduction.
