given in the problem:
2. Use the specific heat and temperature relationship formula to
calculate the heat energy needed
q= m * C. * At

a. a clone will be physically identical to the original, but won’t be genetically identical

have a good day!

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.

i think its 100.

hope this !
