Heredity is BEST described as B. natural abilities that cannot be changed. So, for example, if one of your parents or ancestors had blue eyes, there is a possibility that you are going to inherit blue eyes as well. These are some of the characteristics that are passed down to you by your predecessors, which you cannot change naturally, but rather by undergoing an operation.

Along with the credits thing it could also affect your health in a type of way. you need to get out the house or off the computer and interact with people. if you stay taking online classes and are not going outside and socializing that could affect your health or your mind. your mind will start to form into you being alone and you would want to be alone over anything. so public or private school would be good because there is people around you to and support you.
