Ionic and covalent bonds help arrange atoms into unique structures for proteins like hemoglobin. Why is this necessary? (1 point) a. The ionic bonds alone in a protein help determine its function

b. The structure of a protein allows it to carry out its unique function.

c. The bonds help hold the protein together but are unrelated to the function

d. The structure of the protein allows it to carry out whatever function is needed the most

B. Is the correct answer

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
