The process of natural selection is based on the assumption that
(1) environmental changes will cause changes in body structures in individuals
(2) most changes from generation to generation are the result of mutations
(3)part of the population of organisms always remain stable
(4) different traits inherited by offspring have different survival value
IS THE ANSWER 3
No.

oh its 4
Right. It's 4.
No, the correct answer is (4) - different traits inherited by offspring have different survival value.
To arrive at this answer, we need to understand the concept of natural selection. Natural selection is a key mechanism in the theory of evolution, proposed by Charles Darwin. It is the process through which certain traits or characteristics become more or less common in a population over time, based on their relative advantages or disadvantages for survival and reproduction.
Natural selection operates under the following principles:
1. Variation: Within a population, individuals exhibit variation in their traits or characteristics. This variation can be inherited from their parents through the process of reproduction.
2. Heredity: Traits that are advantageous for survival and reproduction have a higher chance of being passed on to future generations. This occurs through the process of heredity, where offspring inherit traits from their parents.
3. Differential survival and reproduction: Some traits provide individuals with advantages in their struggle for survival and reproductive success, while other traits may be detrimental. Individuals with advantageous traits are more likely to survive, reproduce, and pass on their traits to future generations.
4. Accumulation of favorable traits: Over time, through repeated cycles of variation, heredity, and differential survival and reproduction, favorable traits become more common in a population, whereas unfavorable traits become rarer or may eventually disappear.
Therefore, the correct answer is (4) - different traits inherited by offspring have different survival value.
