Answer:
Heredity is a term that refers to something we have gained from our parents, they can be some physical traits like appearance or behavioral traits like generosity, ethics etc.
When we talk about development of an individual, science has proved that both heredity and environment play a crucial role. There is no doubt that certain things are predetermined in our genetic make up like our height, weight and complexion etc but there are several ways in which environment influences and modifies those traits.
Let's take some examples:
- A kid is born in Africa whose parents inherited just appropriate and ideal height and intelligence to him, But he was surrounded by the conditions where he could not get sufficient food , minerals and nutrients that hindered not only his physical growth and development but his intelligence level did not reach that potential too that was predetermined in his genes. So, we can say that environment influenced the kid and modified the traits he inherited from parents.
- Similarly, there are many boys that inherit fair complexions from their parents but they have a lot of sun exposure due to out door sports and activities. So, parents observe that after teens their complexion is getting towards darker tone although in preadolescence they were just as fair as other siblings. This is proven by studies that sun exposure turns the skin tan and darker than original tone.
Therefore, we can say that both Heredity and environment play an important role in determining human development and behavior.

Answer:
<em>The correct option is "a discussion of any errors in the experimental data"</em>
Explanation:
The analysis section of a lab report describes the critical analysis of the experiments and observations that were carried out. It also describes the defaults in any observational method which they got to know during the experimental method. The analysis section also tells how the experimental and observational methods could be made better. Hence, we can say that the analysis section of a lab report shows discussion of any errors in the experimental data.
The answer is an overhunting.
<span>The bottleneck event means drastic reduction of the population size because of environment changes. The consequence of this is the reduction of genetic variation. The bison population is a good example of the population bottleneck. The bison population drastically reduced its size due to overhunting which culminated at the end of the 19th century, when bisons almost extinct. </span>
