Goal: Show what is happening in an athlete’s body during exercise. Do: • Change this model of the starch, glucose, and oxygen molecules in a healthy body during exercise to model what happens in an athlete’s body during exercise. Tips: • Refer to your data table to identify the differences between the healthy body and the athlete’s body. • Note: You’ll be revising and handing in this model later in this lesson. In the space below, describe how your model is different from the Healthy Body Model.

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.  

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
