Answer:
<h2>A. Temperature x Entropy (TS)- The total unusable energy of a system </h2><h2>B. Free energy (G) - The total usable energy of a system</h2><h2>C. Entropy (S) - The disorder of a system</h2><h2>D. Enthalpy (H) - The total energy of a system</h2>
Explanation:
<u>The free energy</u> of the thermodynamic system is such a type of energy that is present or available to do work. So it can be called as total usable energy of the system.
<u>Entropy </u>is a thermodynamic quantity that explains about the disorder or the randomness of the system. As the temperature increases, the entropy of the system also increases.
<u>Enthalpy</u> is a thermodynamic quantity that explains the change in the internal energy so consider the total energy of the system.
You know that during cellular respiration, energy is converted from glucose, in the presence of oxygen, into numerous ATP molecules. Glucose contains lots of energy, but that energy must be converted into a form usable by cells.
Carbon dioxide, sunlight, and water
Answer:
excretory system and circulatory system
Explanation:
Blood is part of circulatory system and as it move through various organs it exchanges the gases i.e give oxygen to the cell and take carbon dioxide from them. After taking CO2, the blood becomes impure and hence it passes through the kidney before going to the heart. Kidney is part of excretory system which removes carbon dioxide from blood and thus purifies it.
Answer:
Living organisms that are heterotrophic include all animals and fungi, some bacteria and protists, and many parasitic plants. The term heterotroph arose in microbiology in 1946 as part of a classification of microorganisms based on their type of nutrition.
