Question

Could someone help me out with these questions???

Answer 1

Answer:

1. If an organism has high biological fitness in one habitat, this does not mean it will have high fitness in another. This is because organisms adapt accordingly to their environment. Therefore, since there is variability among habitats, this does not guarantee that the organism will always have high biological fitness.

2. Natural selection produces changes in populations. Individual organisms are directly impacted by it, as it determines their survival rate, but the only genetic changes would occur in a population.

3. If there are no organisms with varying traits in a population, they will likely go extinct after a major environmental change. This is because natural selection will remove all organisms who are unable to survive in the new environment. If the population does not have the variability to survive this, then they will go extinct.

Answer 2

Answer:

1) The answer is no, because high biological fitness in one environment doesn't have to be high in another environment.

2) Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways

3) I would say that the population will not only evolve (change in its genetic makeup and inherited ... When a phenotype produced by certain alleles helps organisms survive and ... That is, it may have some positive and some negative effects on fitness.
