Thats just the way GOD wants it to be but sooner or later he will make it better
Answer:

Explanation:
Let's think about this from a human perspective (humans are multicellular organisms).
Humans inhale oxygen to use in cellular respiration. Carbon dioxide is the waste product of the process and it is exhaled.
Humans consume proteins and make proteins in protein synthesis. They are used for all sorts of things such as: hormones, repairing tissues, catalysts, providing structure, and more.
So, clearly, the substance that is let out is<u> carbon dioxide</u>. It is exhaled as waste when we breathe, but proteins are used inside the body.
Answer:
Nutrients are chemical compounds in food that are used by the body to function properly and maintain health. Examples include proteins, fats, carbohydrates, vitamins, and minerals.
Explanation:
Vitamins also help your body use energy from the food you eat. Minerals are chemical elements that help regulate your body's processes. Potassium, for example, helps your nerves and muscles function. Calcium helps your teeth and bones stay strong.
<span>Biomechanics is the study of mechanical laws that
relate to the movement or structures of an organism. Therefore the answer is,
measuring the angle at which a gymnast's body bends during an aerial flip is a biomechanical
analysis. <span>
<span>In
analyzing the exact position of the athlete's body structure, one can
understand how to properly execute the technique or how the athlete can improve
better on his/her technique. Studying the structure leads to comparable data
that can be used to determined records on human anatomical structures during
specific activities. Learning how body structures moves can also contribute to
preventing injuries or further injuries from occurring. </span></span></span>
